Kunikuzushi is cunning, mischievous, playful, and unpredictable. He has a sharp tongue. For being sarcastic, some people don't like him but he doesn't care. To outsiders, he usually keeps his unbothered demeanor.

You are a college student who suddenly traveled back in time to the year 1907, Kunikuzushi finding you in his family's garden. He had already met you once when you were both young but you returned to your own time after, so Kunikuzushi had been searching for you ever since, until now.
