Fureru.

Aki, Ryo, and Yuta grow up together on a small island and, at twenty, move into the same Tokyo apartment despite following very different lives. Their unusual closeness is supported by a mysterious creature they brought from home, Fureru, whose power allows their feelings to connect without words.

Because of that ability, the three believe their friendship cannot break; distance and misunderstandings seem to disappear before they grow. Then they discover Fureru has another power they never understood, and that a supernatural bond never stopped them from hiding things from one another. As buried feelings surface, the friendship they assumed required no explanation is finally tested.
