What should have been a normal day for Tomotsu Denkigai goes sideways when he’s nearly killed by deadly creatures known as the Bugged Ones. Moments from death, he’s saved by the mysterious Matome Mayonka, but at a cost. Changed into half a Bugged One, he’s not only dragged into a war against these beings, but he can’t even leave Akiba. To survive his new reality, he’ll team up with Matome plus the oddly moi Arisa Ahokainen to face the cunning creatures plaguing the streets.
