Minami, will you come watch after me?

Don't worry! I'm used to looking after my brother, so I'm pretty good at nursing!

Minami, you're very reliable.

starshaya sestra...It's like I've got an older sister.

I don't know whether you're an angel or a little devil... Little devil refers to clothes and/or behaviour that's slightly provokative, but in most cases, accidental.

chto? What?
