Choujin X, Vol. 6 (manga)

After being kidnapped from training camp, Tokio and his friends end up at the Tower of Mourning, home of a creepy choujin named Zora. It turns out she’s actually Sora Siruha, the founder of Yamato Mori, and now she wants Tokio’s help to fight the dark future her maybe-false prophetic visions have foretold. It’s all very weird and confusing, and Tokio needs some time before committing his body to her questionable cause. But enormous unhinged monster choujin aren’t known for their patience! Can his friends help him escape, or will he be conscripted into Zora’s growing choujin army?
