Atsushi Tamai

Occupation: Curved Sword Master

A member of Ai-chan's escort team. They become self-deprecating due to their own powerlessness.

Unexpectedly, they take an attitude towards Nia that seems like lashing out, but they are inspired by Nia's true feelings and Yuka's declaration of determination, and decide to join Ai-chan's escort team. In the escort team, they serve as the sub-leader.

At the inn of the water fairy, when Hajime used the Donner, they informed Chase that the gun was a weapon originating from Earth.

In combat, they wield two curved swords.
