I thought I was reading Yuri manga for a sec. The guy looks too cute in some panels. (Not that I mind.) Although if he ever lifts his bangs Vergil-style, he’d definitely look cool.
If I ever want to self insert, I'd self insert as the main girl. She's a fuckin G. Also, looks like Truck-kun failed to do his job properly. Now there's possibly a world out there dying because there's no hero coming to save them.
