One of those 'Elder Sisterly' things.

Oh god no, that kind of stuff's not gonna be able to deceive...

Sorry 'bout all that, Kagerou Onee-chan♡

Use nice words when facing your elder sisters, okay.

If you say something as cutely as humanly possible, then it'll generally reach a conclusion.

At times like this, see, Arashi?

Geez, there's just no helping you, is there!

After waking her with a splash of water, she became that state there.

She asked me to ensure that I woke her up in the morning, see.

Really, she's just such a troublesome girl.

Ah, Shiranui-nee.

Kagerou-nee looks seriously pissed!
