Yeah, yeah! He was the Super High School Level Mechanic! He was kind of funny, though he liked to creep on Sonia-chan a bit.

... Though, Kazuichi-chan didn't get much chance to really show off his mechanic stuff for as long as I knew him, now that I think about it. Ibuki didn't even know him for a month.

Then again, with memory wiping shenanigans going on, maybe Ibuki knew him for longer than that? Who knows... maybe someday Ibuki will get her lost memories back.
