[Prince of Tennis] I'm the Protagonist's Older Sister, Yet I've Ended Up at Rikkai Dai

I transmigrated and got an older brother named Echizen Nanjirō.

Then I was adopted by Echizen Nanjirō and got a cute little cousin, Echizen Ryoma, too, haha.

But when I was nine, Ryoga ran away from home.

Echizen Ryōsakura: What the hell? You said you'd take me with you! I'm not playing with you anymore!!

※

To rebel against the old man, Ryōsakura decides to go to Rikkai Dai.

Besides, I was a Rikkai fan before transmigrating, so going to Rikkai Dai afterward is only natural!

Of course, Rikkai Dai's three consecutive national championships are guaranteed!

And so Ryōsakura secretly lures her cousin to Rikkai Dai (√)

And then...

Ryōsakura: Hehehe, I can go wild shipping all the different pairings with our captain~!

※ If you praise Rikkai Dai, we're sisters from different mothers and fathers.

※ Rikkai Dai: sixteen consecutive Kanto titles and three consecutive national titles, guaranteed!

※ Ryoma goes to Rikkai Dai.

※ I only realized after naming the protagonist that Ryoma x Sakuno = Ryōsakura... orz. I don't ship them /covers face

※ About pairings... After much thought, I decided to make this a no-pairing story. The heroine has a life of her own. Though she's closely involved with tennis, she won't play professionally, just enjoys it casually in her spare time (I'm sure of it).

※ This is a short story.
