So there's this hentai comic going around called mega w's 女が全て下品なビッチになった日常 中編 yeah I know, quite the mouthful.
Funny thing about it is that it's actually bimbofication related, not just ganguro corruption. The magical smartphone app reduces the victims intelligence and reasoning while increasing athleticism and eroticism.
Apparently, there's a new part out where the main girl gets the transformation treatment, but I can't find it.
The stats on the phone are (according to some guy on hypnochan) listed as:
知能 chinou intelligence
運動 undou (in this context) athleticism / physical strength
理性 risei sense (as in common sense or reasoning)
エロ ero eroticism
Here's what i assume is the first part only on e-hentai:

EDIT:Actually, that IS the second part the first part apparently showcases a ton of different girls (her friend, girls on the subway, her teacher, a classmate, and some random kid)
TIME TO SEARCH
