Synopsis

In a world of magic, the powers and future of a mage are predetermined at birth through so-called "Crests", four symbols that categorize a human's aptitude for magic. Lamenting the fact that his crest was considered ill-suited for combat and only useful for magic augmentation, an incredibly skilled sage decided to reincarnate thousands of years in the future. Reborn as Mathias Hildesheimr, a six-year-old boy and the third son of a duke's family, he attains the crest of close combat he always desired. Unfortunately, it is also discovered that mankind's knowledge of magic and swordsmanship has drastically deteriorated in this era; only shoddy magic equipment can be sporadically found, while even the most basic spells have been forgotten. To add insult to injury, his current crest, once hailed as the most powerful, is now viewed as the worst. When Mathias becomes 12 years old, his unrivaled swordsmanship lands him in the Second Royal Academy. Shattering prejudices, he promptly makes ripples in the academy and beyond. However, the former sage uncovers signs of dark forces working in the shadows, and with humanity weaker than ever, it is up to Mathias to thwart their evil plans.

Voiced by: Nina Tamaki (Japanese); Kayleigh McKee (English)

Known as "Gaius" in his previous life around 5000+ years ago, he reincarnated himself as Matthias in order to obtain a new Crest by his Reincarnation magic, which would be better than his "First Crest". He was able to successfully achieve his goal upon reincarnation in the form of "Fourth Crest". His main goal in life is to gain power so that he can challenge and fight against the powerful Monsters in the Outer Space.

Lurie Abendroth (ルリイ＝アーベントロート, Rurii Ābentorōto)

Voiced by: Haruka Shiraishi (Japanese); Lizzie Freeman (English)

The third daughter of the Lepucius House. She is a best friend of Lurie and bears the "Second Crest". Although her magic power is lower than Matthias and Lurie, she has been good with her archery skills.

Iris (イリス, Irisu)

Voiced by: Shiori Izawa (Japanese); Brianna Knickerbocker (English)

Also known as the "Black Dragon Iris", she is one of the oldest and strongest Dragons still alive.

Genius sorcerer Gaius laments that with the three magical crests he was born with, Creation, Power, and Rapid Firing, he cannot grow any stronger, so he decides to reincarnate in the future. Reborn 5000 years later as Matthias Hildesheimer he gains the fourth crest Close Combat, regarded in this time as the Weakest Crest. Deciding to join Second Royal Academy Matthias travels to the city where he discovers magical knowledge has drastically decreased. He meets fellow academy hopefuls Lurie and Alma and enchants a magical sword for Lurie, who develops a crush on him. After defeating Knight Captain Guile with the sword and showing his advanced combat magic Matthias is accepted into the academy with Lurie and Alma. Headmaster Eduard asks him to teach the other students his Wordless casting, the ability to cast spells without speaking, a skill normally rejected in academic circles, in time for the next inter-academy competition. At the competition against the prestigious First Academy Matthias realizes one of their students, Devilis, is a Demon and defeats it after exposing it to the audience. He realises the decline of magical knowledge and wordless casting must have been caused by demons to make humanity weaker after he himself almost drove demons extinct 5000 years ago.

The King personally thanks Matthias for defeating a demon, even though to Matthias it was barely a challenge. For his reward Matthias requests access to the kingdoms dungeons. The king reveals the most powerful sorcerers of the kingdom vanished after the demons defeat, causing Matthias to realize they must have been demons who infiltrated human society to destabilize it. Now unable to keep hiding Matthias reasons they will assemble armies to attack the kingdom. He thus gains the kings permission to continue teaching wordless casting while gathering materials necessary to cast a magical barrier of protection over the city. To gather resources Matthias decides to raid a dungeon with Lurie and Alma to increase their combat power, teaching Alma to use a bow and Lurie how to craft and enchant weapons and armor. After reaching floor 10 and increasing their levels Matthias descends to a much deeper floor alone to gather adamantite for the barrier. While there he also defeats a Boss Monster, his magical power coming to the attention of several demons. Matthias learns from Lurie and Alma that his former identity as Gaius is worshipped as a God of Magic.

After selling the boss monsters magi-stone, which Matthias considers too small for the barrier but everyone else considers big enough to be a national treasure, he splits the money equally with Lurie and Alma. Two demons appear in the city to avenge the death of Devilis. Lurie and Alma distract the weaker demon, allowing Matthias to defeat the stronger demon by himself. The king once again rewards them, Matthias with the location of every known dungeon and Lurie and Alma with a cash reward. Matthias realizes a demon is watching the throne room with a surveillance spell and manages to injure the demon on the other side. The king recognizes the demons voice as Erhard, his former Mage Captain. With Erhard’s location discovered Matthias decides to find him, but as it would take a year to travel the distance Matthias takes Lurie and Alma into the mountains and introduces them to Iris the Darkness Dragon who, despite being unimaginably scary to the girls, is one of Gaius defeated enemies. She revealed years previously an accidental magic explosion returned human society to the dark ages, explaining the current lack of magical knowledge, and also damaged her wings which Matthias now repairs. With Iris carrying them they travel the distance to Erhard in only one day.

After breaking into Erhard’s home Matthias exposes him from behind his spell of invisibility. Refusing to believe Matthias is the one who injured him due to how long it should have taken the real Matthias to travel from the academy to his home, Erhard attacks but is quickly weakened by the magi-toxin on Alma’s arrows, severely affecting his magic and making defeating him easy. Matthias also exposes a stronger mist demon hiding in the forest and after a short fight curses the demon with a spell to overload his magic, causing him to explode from the force of his own magic. The explosion uncovers a Dragon Vein Pillar buried in the earth, a giant crystal that can tap into the magic power trapped in the earth. The demons had planned to summon an army of monsters just outside the city. Returning to the academy Matthias offer to vouch for Iris to attend the academy in human form. Due to her unfamiliarity with human behavior Iris laughably fails the written exam but is accepted after using unusual methods to defeat Guile in a sword duel and her magic almost destroying the academy arena which Matthias promises to repair.
5	"The Strongest Sage Makes Allies." Transliteration: "Saikyō Kenja, Nakama o Eru." (Japanese: 最強賢者、仲間を得る。)	Shin'ichi Fukumoto	Yūji Kobayashi	Toshinori Fukushima	February 5, 2022 (2022-02-05)
Preparation of the barrier goes slowly with only Second academy students. The King requests First academy offer assistance, but headmaster Facus refuses to associate with their inferior academy. Matthias suggests holding a second inter-academy competition and Facus agrees provided Matthias does not compete. Facus brings 50 students to compete against 5 from Second academy, but they easily win using wordless casting. The king, who had been observing, sees that Facus had been forcing his students to ignore his order to switch to wordless casting and has Facus arrested. Facus' students, who did not like him much, happily cooperate with Second academy and learn wordless casting. Still requiring a much larger magi-stone for the barrier Matthias takes the girls back into the dungeon, much deeper this time, and harnessing Iris' magic summon a dragon. After a long fight and using all their new skills the dragon is defeated and yields a magi-stone of sufficient size for the barrier. Matthias also decides Iris has improved enough to become an official team member. Iris trains to be a better fighter with her human body while Matthias and Lurie use the resources harvested from the dragon to make swords for themselves, a new bow for Alma and a spear for Iris capable of withstanding her power.
6	"The Strongest Sage Leaves the School." Transliteration: "Saikyō Kenja, Gakuen o Deru." (Japanese: 最強賢者、学園を出る。)	Toshinori Fukushima Makoto Sokuza	Hiroki Uchida	Masayuki Takahashi	February 12, 2022 (2022-02-12)
As Matthias begins constructing the barrier the demons attack, forcing Matthias to put Lurie and Alma in charge of defending the city while he and Iris begin distributing adamantine to complete the barrier. The students hold back the demons while Lurie crafts an arrow for Alma capable of defeating the first demon to attack. Following his death more demons arrive but Matthias, having finished the barrier in time, defeats them then activates the barrier, preventing demons from being able to enter the city ever again. Unfortunately, while the demons are defeated their army of monsters, summoned using another Dragon Vein Pillar, is still outside the city. The students defeat the first wave of monsters using wordless casting, then retreat so Matthias and his team can take the more powerful monsters. The most powerful, a Void Eater that consumes other monsters to grow, is manipulated by Matthias feeding it certain spells so that it will provide more useful resources once defeated. With the Void Eater defeated Matthias decides he has to leave the academy to find the Dragon Vein Pillars. Eduard lets him leave but keeps him listed as a Scholarship student in case Matthias adventures get him in political trouble the academy can then protect him from. Alma, Lurie and Iris also become scholarship students so they can go with him on his quest.

Matthias decides to explore Melkia dungeon but learns since he reincarnated an adventurer city has been built over it. Alma and Lurie try to avoid passing through a forest on the journey but accidentally make Matthias curious when they mention an intelligent monster that lives there. As usual, Matthias easily defeats the monster. Reaching Melkia the group learn the Melkian lord has been making the city unsafe and controls the adventurer guild, meaning adventurers have to do whatever job he gives them. Most of the adventurers come back from a monster hunt severely injured requiring Matthias to heal them. Matthias learns the previous lord passed away suspiciously, causing him to suspect the new lord is a demon making adventuring as dangerous as possible to kill off strong adventurers. He sends a secret letter to Eduard to pass to the king then plans to spend the next day hunting the monster that injured the adventurers; however, due to the awkwardness of all sharing a room together Matthias and Lurie do not sleep at all. Regardless they defeat the monster easily, drawing the attention of the lord who appears to have spies in the guild and even adventurers working directly for him who begin following them.
8	"The Strongest Sage Saves the City." Transliteration: "Saikyō Kenja, Machi o Sukuu." (Japanese: 最強賢者、街を救う。)	Naoki Murata	Yūji Kobayashi	Iku Suzuki	February 26, 2022 (2022-02-26)
Matthias easily leads the adventurers into a trap where Iris knocks them out. In response to his letter the King sends his royal proxy, Eik, to order Matthias to take Lord Dokiel into custody. Defeating Dokiel's guards Matthias arrests him and Eik takes him to face the King. Too late, Matthias realizes the demon controlling of Melkia have found the dungeon’s dragon vein and summoned a monster horde outside the city. Entering the dungeon Matthias leaves Lurie to cancel the spell placed on the vein by the demons, with Iris and Alma guarding her, while he locates the demon in charge. Eavesdropping on the demons' telepathic conversation Matthias determines there is an even higher ranked demon somewhere else advising the demon on how to beat Matthias. It is also revealed the master knows about the sorcerer Gaius, meaning he is very old, smart and powerful but is unsure if Matthias is Gaius' reincarnation or not. Even with his masters help the demon is overwhelmed by Matthias and beheaded. Lurie restores the vein, causing the summoned monsters to vanish. Via the remaining telepathy Matthias and the master demon casually threaten each other and decide to meet in the future. Matthias becomes excited at the thought of an actual challenge.
9	"The Strongest Sage Duels." Transliteration: "Saikyō Kenja, Kettō Suru." (Japanese: 最強賢者、決闘する。)	Kai Hasako	Yūji Kobayashi	Kai Hasako	March 5, 2022 (2022-03-05)
Matthias had captured the demons magical signature in a magistone but requires a device he created thousands of years ago as Gaius to track him. The device is currently across the border in the Radinia Alliance, a group of allied kingdoms, and to cross the border he needs permission from the King. Returning home they find the academy demolished to make way for a new upgraded academy. With permission to cross the border Matthias learns his device is in Folkia Region, an area of such strong magic it is forbidden except for A rank adventurers so Matthias agrees to take the A rank promotion exam. The adventurer, Giluas, is ranked S, higher than A, and is obsessed with fighting. He nonchalantly promotes Iris, Lurie and Alma but insists on fighting Matthias who has become famous as a demon slayer. Giluas proves to be the strongest opponent Matthias has faced, even able to copy Matthias combat moves, yet Matthias is still victorious. After advising Giluas how to get even stronger with spells Giluas is grateful yet irritated at having to read books to learn. He advises them Folkia is dangerous and adventurers frequently vanish. Straight away in Folkia border guards try to secretly place demon tracking spells on them. Bandits attack but are swiftly put to sleep. Unfortunately Lurie and Alma also accidentally fall asleep.

The group continues to Folkia and they immediately sense 32 disguised Devils, a type of demon that is weak at magic and prefer to fight in large groups. Rather than sneak past the town guards Matthias uncovers a concealed tunnel. Emerging into Folkia they see that citizens have all been hypnotized to keep them mindless while they work in a large factory. Protecting themselves from the spell they infiltrate the factory and find they are refining Lankin Demon Ore. One ton of refined ore can make a bomb powerful enough to destroy an entire country, though it is so rare collecting one ton takes decades. Facing Devils is dangerous as they can use Sense Share, so once one Devil is aware of them, all 32 of them will know as well. Using superior strategy, the group begin killing the devils one by one until only 10 remain. The remaining 10 decide to use small pieces of ore to blow up the city, only for Giluas to suddenly appear. With only the Devils leader remaining Giluas duels him alone and Matthias is pleased to see Giluas has already improved his spell casting. After a difficult fight the Devil is defeated but not yet dead.
11	"The Strongest Sage Faces a Powerful Enemy." Transliteration: "Saikyō Kenja, Kyōteki to Aitai Suru." (Japanese: 最強賢者、強敵と相対する。)	Makoto Sokuza	Hiroki Uchida	Masayuki Takahashi Toshinori Fukushima	March 19, 2022 (2022-03-19)
The Devil passes on a message he will soon be resurrected, then disintegrates. Matthias realizes the master demon responsible for Melkia was controlling the devil via necromancy to pass on the message. Giluas names the factory’s foreman the new Lord of Folkia. Continuing on their journey they reach the ruins hiding the device and Matthias is forced to conceal the fact it was he who built the ruins. Using his device Matthias confirms the master demon’s name is Zardias and he was sealed long ago because he was too powerful to be killed. Matthias is certain he is too weak to defeat Zardias, and even if he was strong enough their battle would likely destroy the world and push humanity to extinction. Desperate, Matthias uses the device to search for a sword he forged long ago and finds it is somewhere back home in the king’s treasury.

Zardias reveals that all the demons Matthias has defeated have been resurrected inside the barrier to kill Lurie and Alma. Lurie and Alma are saved by Eduard and the academy students and throw the sword to Matthias but Zardias stabs him. Matthias comes back to life, revealing the sword was the most powerful he ever created; if the wielder dies their life force is used to resurrect them. Zardias is defeated but before dying warns Matthias another demon will just replace him. The king once again gives them access to the treasury as a reward. Matthias discovers an adamantine arrow he crafted in his previous life but the matching bow is missing. He tracks the bow to the Isis Company who, not knowing the value of adamantine melted it down so Matthias buys all their scrap metal as well as some magic stones for the girls. Guile informs Matthias of an incident where their neighboring Syhill Empire was attacked by an army of artificial doll soldiers. Due to the complex magic Matthias deduces a demon is responsible and may be in control of Syhill. Later, Lurie suspects Matthias might kiss her but really he just made her a necklace from one of the jewels. Having fully recovered everyone decides to set off to Syhill for their next adventure.

Mobile game

Reception

Rebecca Silverman from Anime News Network gave the first volume of the manga adaptation a C+. She praised the artwork, the hints the story gives about events that happened prior to the start of the story, and that the characters age properly, while criticizing it for being too generic and the pacing feeling rushed and uneven. The following volume earned a B−, with Rebecca Silverman praising the improvements made to the story and pacing, as well as the consistently good art, while criticizing it for still feeling a bit generic, one character getting less development, and some odd translation decisions.
