When Akira's class is magically summoned to another world, his classmates receive heroic powers while he is assigned the role of Assassin. Harboring doubts about the king who summoned them, Akira uses his skills as a master of shadows to investigate — and uncovers a conspiracy that will set him on the run, framed for murder and hunted by the very crown that called him here. Master of shadows and wielder of a jet-black katana, Akira builds his strength in secret, gathering allies across continents of elves and beastfolk while waiting for the day he can claim revenge.

When Akira's class is summoned to another world, his classmates earn heroic powers while he becomes a mere Assassin. Doubting the king's intentions, Akira uses his skills as a master of shadows to dig for the truth — and finds a conspiracy at the heart of the crown.

Betrayed by the king who summoned him and framed for the murder of his friend Saran, Akira flees into the depths of a perilous labyrinth following Saran's last order: reach the bottom at any cost. Finding unexpected allies and enemies in those magical corridors, Akira sharpens his skills and waits for the day he can take revenge.

At the bottom of the ancient labyrinth, Akira encounters a huge talking black cat — a servant of the Demon King who becomes an unexpected ally. After forming a pact, a magic circle transports them both to the elven homeland of Akira's new companion Amelia, where dangerous secrets about her history come into focus.

Having put an old elven grudge to rest, Akira continues his journey to build the strength needed for revenge. His path now leads to the land of the beast-men, where he searches for a smith worthy of forging the ultimate blade.

Akira and Amelia arrive on Brute, the continent of the beastfolk and home to the world's greatest blacksmith. Repairing his jet-black katana will require securing that smith's aid — no easy task with hidden dangers and the toughest adversaries Akira has yet faced standing in the way.

Demons run amok in the beastfolk port town of Ur, and the demon Aurum abducts Amelia. Nearly drained of shadow magic from defending the city, Akira must rely on his restored sword Yato-no-Kami and his companion Night to descend into the deepest level of the labyrinth. An unexpected alliance with the first princess of Uruk may be the edge he needs to face such a fearsome foe.
