A booklet packaged with Harta volume 124 at select stores. It's an anthology of one-shots from Harta collaborators focusing on the theme chibi characters.

The chibi characters are waitresses, gods, gangsters, etc., and are full of individuality. They're so darling and cute as try their best with their tiny bodies. We hope you will watch over them and see what they can do!
