A divine beast Komainu in the form of a girl about 150cm tall, with long green curly hair, a tail of the same color, and horns on her head. She wears a red Hawaiian shirt and shorts. Originally a guardian statue of the Hakurei Shrine, she became a physical entity when magical energy flowed into her. Since she had been watching over the shrine as a statue long before gaining a physical form, she knows the Hakurei Shrine and Reimu very well. She can use a cloning technique to create a single duplicate identical to herself. She is loyal, sociable, and has a very kind personality. She has a pure side but can be quite jealous without realizing it. She possesses many dog-like traits, such as walking on all fours, sleeping curled up, or sitting on the floor like a dog, and sometimes barks with an "Aunn!" sound. She often takes it upon herself to stay and work under the pretext of protection without the owner's permission. She laughs with a "Hehe" sound, eyes closed and tongue slightly poking out. She generally uses polite speech with everyone.
