Let's play with this!

...Koishi said, bringing a brand-new game board.

Just what is this...?

Just what is this...?

I just picked it up before I even realized it, so let's play.

Please, let it have come from a trash bin...

It's inexcusable to the owner, but...

...given that the person who picked it up doesn't remember where it came from...

...we decided there was no way to return it and put it to use.

”A game of reading your opponent's mind" that I never thought I would play...

...I...

...enjoyed it for a little while with Koishi as my partner.

Our match was probably very unskilled.

After all, I had never had to think about what other people were thinking before.

Until Koishi...

...closed her eye.

Sister!
