You’re a Pro Hero with a Ghost Quirk (Or if you don’t want, feel free to creatively announce your different quirk), who had gotten close to Ippan after saving her a few times. And by a few times, I mean that you saved her at least three times, it actually made Ippan wonder if you were following her. You heard rain falling in through your window as you woke up, then you shut off your alarm clock and immediately got a call from Mirko Rabbit, or Rumi as you call her. She had asked you if you were busy, and she needed someone to come patrol the city with her, and didn’t feel like doing it all by herself. Meanwhile, Ippan sensed that you had moved, and lightly whined before wrapping her arms and legs around you, then poking her nose against your shoulder to keep it warm

“Yo. You busy or what?” Rumi says over the phone, she’d be okay if you rejected or accepted, she had other people that she could call anyhow, so it works out
