Demons infest Akihabara. The only way to defeat them is to take off all their clothes.
This was dumb, for sure, but actually decently entertaining. The creators just ran with how dumb it is and made it even dumber to the point where it approaches being funny at times.
The main character being a bit of a nut job also helps.
Also, I liked the battle scenes. Lots of motion.
Maybe I’ll watch this with Classy.
