[Aotu World] You're My Big Brother!

Fifteen-year-old Gray was training on a planet when he rescued an injured girl, and then...

Girl: (blinking her big eyes) ...Um, are you my big brother?

Gray: (completely baffled) ???????

Girl: (happily) So you are!

Gray: Stop following me. I don't know you.

Girl: B-but you're the only person I know! You're my big brother!

Gray: ...Who told you that?

Girl: (beaming) I did!

Gray: ...Don't say things like that.

Girl: I'm not making it up! Look at your eyes! Aren't they purple? Only you, Big Brother, have such beautiful eyes! I love you the most, Big Brother!

1. This is my first time writing a fanfic for 3D Arena. Please excuse the writing.

2. The characters belong to 3D Arena; any out-of-character behavior is on me.

3. Updates will be whenever I feel like it, so please be patient.

4. Still thinking about the pairing.
