## Description
"Make a quick detour today and come back later."
With that, I finished my university classes, killed some time, and then returned home.
When I entered the living room, I was greeted by a sumptuous feast and Sakura and Satsuki.
I sat down, scratching my head in confusion.
Then Sakura said, "Satsuki will be staying with us for a while starting today."
We talked about this and that, but it seemed like all the luggage had already been brought in, so I finally gave in and we agreed.

"Well, she's in that mysterious adolescent phase where she loves sleepovers, she'll get bored of them soon,"
Or so I thought...

However, Satsuki had transformed into a veteran soldier.

I was already struggling against Sakura alone, but now I was completely defeated by the overwhelmingly powerful reinforcements.

The battle continued for a while, and just as our forces were clearly at a disadvantage, a visitor appeared.

"Um, I came to check on you, Onee-san."

However, Satsuki had transformed into a veteran soldier.

It turns out she's Satsuki's younger sister.

She hadn't seen her for a while and was feeling lonely, so she came to check on her.

As we chatted, it seemed like she wanted her to come home soon.

A ray of hope has dawned on our army!

And so my counterattack begins...! I hope so.
