Pupipō! (プピポー!) is a manga about Himeji Wakaba and her small pink monster, Pupipo. It has an anime adaptation.

Plot
Himeji Wakaba is a 5th-year elementary school student. She has the ability to see things that others can't. Usually, they are evil spirits that harm people who are close to her. Wakaba has no friends and rarely smiles.

Sometimes she brings stray animals home, but the parents don't let her keep them. One day, they decide to let her keep whatever she will bring next because they are worried about their daughter.

She brings a mysterious pink monster called Pupipo. No one knows what it is. It protects Wakaba from the other things she sees. Pupipo also helps Wakaba make friends with an occult-obsessed transfer student and solve problems with bullying, therefore making her life better.
