Failure Frame: I Became the Strongest and Annihilated Everything with Low-Level Spells

While on the road to their field trip, Class 2-C's bus is enveloped in light, and the Goddess, Vicius, summons the students and their teacher to another world. The Goddess welcomes the students after appraising their abilities with her crystal. However, Mimori Touka is appraised as an E-Class, the lowest rank... and he's branded a trash hero.

Touka starts to regain the cruelty hidden within him as he defeats monsters in the Ruins of Disposal. He's planning to escape the ruins so he can exact his revenge on Goddess Vicius, but what stands in his way is the reason the Ruins of Disposal have a zero survival rate - the grotesque monster known as a Soul Eater.

After defeating the Soul Eater, Touka escapes the Ruins of Disposal. With the vast EXP he obtained in the ruins, the Forbidden Arts: Complete Works that Anglin left behind, and the Scroll of Forbidden Magic, Touka sets out to get revenge on the Goddess, Vicius. The first step on his path is searching for a nearby village so he can gather information about this world. Along the way, Touka enco...

Touka arrives at the city of Mils, and decides to participate in the conquest of Mils' ruins hosted by the city's lord in order to try enhancing his slime as outlined in Forbidden Arts: Complete Works. There he's reunited with Mist, a woman who joins the expedition for the reward money, and has her help him prepare for their adventure. After he's done shopping in the unfamiliar world, Touka f...

After leaving the Mils Ruins, Touka asks Mist—or rather, the half-elf, Seras Ashrain who was hiding her identity, to guard him on his way to the Land of Golden-Eyed Monsters. Seras happily accepts, and they promise to meet up once the lord's celebration party is over. However, Seras doesn't show up to meet Touka even well past their agreed upon time—

Civit Gartland, the man known as Humanity's Strongest, along with the five dragoons come for Seras' life. Then they learn that the one who hired them to end Seras was Neah's Holy Emperor, Ortola - the man she had served faithfully. After the news breaks her heart, Touka steps up to save her from Civit, speaking carefully as one wrong move could cost them their lives.

Seras has sworn to become Touka's sword in his quest for vengence against the Goddess Vicius, so Touka follows Seras to Ulza's royal capital, Monroy, the gateway into the Land of Golden-Eyed Monsters.

Eve's final bloodsport match is tomorrow, but the duke running the colosseum is plotting to make a show of killing her off. Touka tries to warn Eve of the scheme, but she can't bring herself to believe him...

Touka sets a trap for their Ashint pursuers and lies in wait for them in the forest. Their leader, however, is keen enough to see through the ploy. Can Touka stay one step ahead of him to achieve his goals?

At last, Touka's group reaches the Land of Golden-Eyed Monsters. As they fight their way toward the Witch of Taboos, something curious begins hatching. Meanwhile, the students of Class 2-C have also made it to the Land of Monsters to grind levels.

Touka comes up with a reckless plan to save his party from the onslaught of monsters—one that puts him in grave danger. Class 2-C also gets caught up in the attacking swarm with fatal results, and Kobato goes missing.

As Touka braves the horde and the human-faced monsters, he'll have to dig deep and muster every last ounce of his strength in order to come out on top so that he can exact his vengeance upon Vicius and keep his promise to Seras.
