Clean Witches

The Clean Witches are a two-child volunteer duo from My Hero Academia: Team-Up Missions, devoted to keeping their town's streets free of graffiti and grime.

Both are heteromorphs. One resembles a cat with light fur and a large spot across the face, the other an owl. They dress the part in long robes and pointed hats, each marked across the back with a paint roller emblem. Cats and owls both carry old folkloric ties to witchcraft and sorcery, matching the costume theme.

An illegal support item dealer had taken to using childish scrawls as a code for arranging sales with buyers. The duo assumed it was ordinary graffiti drawn by kids and set about erasing it, photographing every site before and after and filing the results as a record of their work.

Cementoss, Nejire Chan, and Great Explosion Murder God Dynamight came across them mid-job while on patrol. Once the heroes understood the situation they pitched in on the cleaning, and Dynamight spotted the code hidden in the symbols. The duo's records gave him what he needed to crack it and lure the vendors into the open. After the arrests, the pair turned on the heroes with an angry lecture about vandalism.

The group consists of two unnamed children, one cat-like and one owl-like, and is listed as active. They are classified as civilians rather than heroes, working purely as volunteers.
