Iruma Ikaruga is living his best high-school life... until mascot-looking aliens from another world invade with their flesh-eating bugs, seemingly hell-bent on destroying humanity violently and effectively! On that fateful day, Iruma loses everything...his normal life, his best friend, and his crush...until six months later, when he catches a glimpse of her again. Is all hope for humanity—or just Iruma himself—truly lost?
Iruma, along with the T&E elite, embark on their journey to Gullveig. While Iruma is inspired after learning where his beloved Kumano-sempai is headed, Kumano-sempai and the others have already started battling with Sekka Kamuragi’s Phantasma-user underlings… Lulu, Ranko, and Kamuro! It’s human against human. Each of the Phantasma-user’s feelings collide in the 7th volume of the tremorous survival battle, the “Puppet Show”!!
