Start of an Inseparable Relationship

I'm sorry that she's bothered you.

This is my sister, Miho.

I hope you can be good friends with her.

That girl...

is Maho-senpai's sister...?

Miho, you're also in middle school now. You have to stop acting like a boy like that.

Ehh? I'm sorry, sis.

There were just a lot of froggies behind the river.

She doesn't have the slightest bit of a maiden's modesty!

But if I get close to her, I'll also be able to get closer to Maho-senpai!

There's no loss in this!!

Okay. That'd be a big help, Itsumi.

And so our story begins.
