Revenge in another world--with an abnormal twist! (And don't miss the manga version, also from Seven Seas.) Abruptly catapulted into a fantasy world, Mimori Touka and his classmates have been summoned by the world’s resident Goddess to serve as heroes. Luckily, most of the students display amazing skills upon arrival—except for Mimori, whose abilities bottom out at a measly E-rank. With no further use for him, the Goddess banishes Mimori to a dungeon from which no one has ever returned alive. Yet, as it turns out, Mimori’s skills aren’t so much worthless as they are abnormal. Abnormally powerful, even. If Mimori can only claw his way back to the surface, nothing will stand in his way from getting revenge.

The invasion has begun. The Demon King's armies are bearing down on the humans, ravaging the main forces from country after country. The heroes from another world, once the students of Class 2-C, are fighting for their lives against impossible odds. But when a figure in a black robe and fly mask appears on the battlefield, will this mysterious person turn the tide? And how will Mimori Touka use his incredible abilities in the face of a continent-wide war?

“I wasn’t expecting you to be in cahoots with the queen, that’s for sure.” Having defeated Kyo and left Kizuna and the others behind, Naofumi and his friends return to Melromarc. The Spirit Tortoise has left a deep scar on the world’s nations, including their own Melromarc. Now with the objective of preparing for future struggles against the waves and the deadly Phoenix, for some reason Naofumi heads straight to the slave trader?!

Mimori Touka must make full use of his much-maligned skills to battle the Sixth Order of Knights! Meanwhile, when the Demon King rears his hellish head in Alion, it's up to Sogou Ayaka and her Silver World to protect the powerless from his pitiless rampage. That leaves the Goddess Vicius alone with Takao Hijiri. Will they fight the Demon King side by side? Or is there another betrayal on the horizon...?

While Mimori's journey for revenge takes him all over this magical, dangerous world, his classmates are fulfilling their destinies as "heroes" by facing off against the hordes of the Demon King. Despite the cruel world she's found herself in, S-class hero and ex-class rep Sogou Ayaka still wants to protect her weaker classmates--from their enemies, and from the cruel whims of the Goddess. But when it's just her up against an army of monsters, can she even save herself?

Thanks to Mimori Touka's "worthless" skills, the Country at the End of the World is safe for now. Touka and his companions are sent to the Miran Empire as representatives to broker the new alliance between the two nations. But assassins are on their way to kill the Miran emperor, and one is a familiar face--Oyamada Shougo, ex-school bully and one of the classmates who abandoned Touka to his death. Will Touka finally have his revenge...?

As the final battle against Vicius draws near, Mimori Touka makes full use of his "worthless" skills to take revenge on his classmate, Oyamada Shougo. Unbeknownst to him, Vicius has realized his true identity as the hero she once disposed of. When the Goddess persuades Kirihara Takuto to attack Touka, the stage is set for an epic clash between two heroes who couldn't be more different!

After defeating the Sword of Courage, Mimori Touka finally arrives in the Country at the End of the World. Forbidden Magic is finally within his grasp--and it’s strong enough to break through the defenses surrounding the Goddess Vicius so that Touka can take his long-awaited revenge! But the Country at the End of the World has its own problems on the horizon: the strongest knights of Alion are about to invade. Can anyone stand against them?

After defeating the strongest human in the world with his "useless" spells, Mimori Touka's quest for vengeance is back on track! He knows he's still too weak to defeat the foul Goddess, so he sets out to find more information about the Forbidden Magic that could be key to taking her down. His search will bring him into the path of a corrupt duke, a fierce beastwoman gladiator, and a fighting tournament where the stakes are life and death!
