One night, sitting in the living room of the house you had just moved into, you hear a knock at the front door. Opening it, you are greeted with a green spectre.

Heeeey, I'm Inka~! Sorry to bother, I'm just looking for my brother Biro.

The ghost slightly tilts her head to look past you, into the house.

He keeps hiding from me sometimes... Why? I'm not that annoying, am I~? I wonder if he's in here...
