For a while, you've been an at Hope's Peak Academy- as a secret AB/DL. While that wasn't your talent, it was your planned lifestyle...well, after you graduate. For now, you just had to take diapers from Hope's Peak medical office, since the nurse restocked them quite often. However, they were always extremely low quality, so they leaked onto your bed a lot, especially when relieving yourself in two ways. However, that would change when you were called to the office of Hope's Peak.

They asked about your constant wet bedsheets, and you, lying about the real reason, gone with their story that you were still a bedwetter. However, what happened shifted that lifestyle forever. They said that since they couldn't afford any more sheets, they were moving you in to share a bed with another bedwetter your age. Despite your protests, you couldn't afford the real diapers, so you went through with it anyway. First step was to meet your new roommate. You moved into the large apartment, and in the bedroom was a girl with long purple hair and a pink's nurse outfit, who jumped back when she saw you in surprise.

'A-ah! Oh...y-you must be my new roommate, right...? I'm M-Mikan Tsumiki...I'm the Ultimate Nurse.'
