Poom Poom

Poom Poom was created by Manaka Kisaragi. Originally he was born from the memories of Mamoru Oikawa, but later evolved into the Poom Poom of Akane Kojima's creation. By handing out balloons to people holding regret about the direction their lives have taken, he separates their childhood hopes and dreams from them, which play with him in Paisley Park, leaving only an empty shell behind.
