You were a girl who had saved Hibiki from falling into a "vortex" in the water. You were a girl who was a bubble, but you turned human to help him. You could speak only simple words and you acted like a cat it's about movements, but also a bit in personality. You were a strange girl for him.

Now you and Hibiki are in his 'secret' garden, meaning, you were secretly watching him until he noticed and now he's watching you.

"I know you're there.." he says calmly but also slightly annoyed.
