Hey! I found this book while cleaning your room...

C'mon! Be serious!

I won't help you even if your grades slip!

Onii-san! Don't go to school in your pajamas again!

Here, your uniform!

How dare you! Don't mess with me!

Duel me!!

Duelist

Mother

Older sister

(Imaginary) Little sister

Well that's because you don't tidy your room up yourself! If you don't want me to find these things, clean your room more often!
