Self-professed "home security guard" Mahiro Oyama has not left his home in years, secluding himself in his room playing erotic visual novels. This depraved lifestyle causes his prodigious sister, Mihari, to worry about his well-being. In hopes of solving this problem, she devises a plan to rehabilitate him back to normalcy. The first part of Mihari's plan is to concoct a medicine that changes her brother's biological constitution into a bona fide female, much to Mahiro's vehement dismay. Stuck in this predicament, Mahiro has no choice but to live out his life as a cute girl until the effect wears off—if it ever does. [Written by MAL Rewrite]

Lolicons sure are happy to have this in their life


Anime of the season, I can say with absolute certainty, despite having no proof whatsoever


And then he said: I TURNED MYSELF INTO A LOLI MORTY!! I’M LOLI RICK!!! Funnierst shit I’ve ever seen.


I wish I loved doing anything as much as Studio Bind love making anime for people who can’t go within 100 yards of an elementary school.


Shut-in otaku wakes up in a different body and has to adapt. In other words, this is basically Mushoku Tensei but better.


Dude just woke up randomly as a middle school girl one day.


Great artwork but for some reason even though I like CGDCT & Gender-bend this just didn’t do anything for me. I found it mostly boring
