ATRScans Chapter 54.5

It has this "appeal to fetishists" vibes with all that "random peeing constantly", is this what counts as humor now? Or maybe it's winks winks fanservice of some type?
I went into this expecting something funny but it's just a SOL fetishist mango a la CGDCT, kinda boring.
It isn't explicitly bad per se, it's just boring. It isn't willing to delve further into science hijinks, nor is it willing to delve into the actuality of a change in sex or the morals around Mahiro's unwanted change. It's basically just a cute girls doing cute things manga.
Also the mangaka puts their piss fetish in the work repeatedly, so uh, reader beware.
