Summary
Takumi Sumino just wanted to keep his friends alive and make it to day 100 without any mishaps or casualties. When all the girls at the SDU suddenly come down with a strange incurable incontinence disease, however, he gets roped into finding a solution for their problem...by putting them in diapers. If having to keep their embarrassing secret from the other guys wasn't a big enough problem, Sumino found himself starting to strangely enjoy this new status quo, a little too much.
