My Wife is a War Criminal! (and a VTuber or Something)

Takamura Kei was just a normal guy with an unlucky streak. Shortly after his parents died in a horrific car crash, he was laid off from his job as an engineer. His parents left a note saying that they had one thing left to give him. Little did he know, that last gift was an arranged marriage with one of the most powerful and dangerous people in the world: Usada Pekora.
