Kuudere Nee-chan Kansatsu Nikki ~Himitsu no Onani, Tousatsu Shichaimashita~

I have an older sister.
My older sister, Rikka, is usually quiet and aloof, just like the cool, downcast heroines you see in anime.

(If this was the 2D world, this could be considered a cute trait... sigh...)

One day, something like that happened...

(What happened to my room??)

I can't quite describe it, but something just felt off.
Then, after a series of events, I started observing the room regularly.

(Is something on the screen?)

When I played it back, I saw a surprising sight...!
