What Should I Do Now That My Friend Has Turned into a Beautiful Girl?

This book has shifted to a youthful slice-of-life story.

I woke up one day to find that my best bro had turned into a girl, and apparently awakened some kind of superpower?

Why can she suddenly control liquids?!

Wait, why do I get someone else's abilities whenever I put on one of their cosplay outfits? Of course, it only works with women's clothes...

And even ordinary women's clothes have special abilities...

Anyway, this is a story about a surreal modern city... probably a tale about my bro turning into a girl.
