Tamon-san no Okashi na Tomodachi

Utsui, a high school senior from Osaka, grows up in a family that openly supports love for anyone. Despite this, she finds it hard to feel romantic emotions. Among the various guests at her home, she grows close to Tamon, someone who regularly talks to unseen supernatural entities. When Utsui reaches out, a small, unknown creature that belongs to Tamon appears—though it cannot remember its own name.
