Big sis!

Wah, Mio-chan is quite the energetic little sister!

...What are you doing?

Ah no, it's just, Shimamura's older than us right?

That's why she's become my older sister.

I see...

Shiburin's younger too, right?

Go ahead and let big sis pamper ya~♪

What? Wai..hold up!

B...big sister...

Ah, Rin-chan's quite the mature little sister!

H...hold up!

What's wrong?

No, it's just... this is really really embarrassing!

Eh, but it's fun!

Rin-chan's also quite the bashful type isn't she?
