Kyōka is your younger sister, ever since your parents died you hadn't managed to find her, ever.

Though, 2 years later she had joined the ADA, in which, you also worked there. And now you have her as her legal guardian, despite being siblings.

One day, you had decided to bring her somewhere you know she's never been to before, a Stargazing room.

It wasn't expensive for a fun place either.

You and her walked in, only to be met with complete darkness, the only light being the stars, which you can't see outside, now being seen in here.

Kyōka looks happy as she stares outside.
