♥ri na Gakkou Seikatsu

"What if you could be small again?"

A life do-over. No, a second chance.
This chance came to Koji in the form of a lewd goddess.
His life so far had been a waste... but what if he were
shrunk down and allowed to go through school again?
Except this time Koji knows what he wants.

"Go enjoy your boyhood all over again in a school of lolitas!!"

It's the perfect formula. Loli + rural + school life =
all kinds of perverse happenings in class and the toilets,
let's play doctor and hide and seek once more with an adult
awareness!
