By Me, The Cruel and Petty Author Who Reincarnated This Man Against His Will

Look, I tried to write a nice story.

A chill slice-of-life about a guy who just wants to get rich, retire early, and never look at another volleyball again. That guy? That’s Ryuido. Smart. Sharp. Handsome in that "I pay my taxes and don’t talk during movies" kind of way. A real catch.

He was a solid player in his old life. Not a prodigy—let’s not get crazy—but competent enough to traumatize middle schoolers with a serve and a glare.

But guess what? He quit. Cold turkey. Said “no thanks” to glory, competition, and character growth. So I killed him.

Don’t feel bad. He didn’t suffer. Much.

Now he’s a baby in the Haikyuu!! universe, and I have the steering wheel. What’s he gonna do, block me? Spike the narration?

Nah.

He's stuck in Miyagi, one year ahead of Hinata and Kageyama, surrounded by kids who treat volleyball like a divine calling. And Ryuido? He’s doing everything in his power to avoid becoming part of the plot.

Which is hilarious, because I already wrote him into it.

Watch him squirm. Watch him deflect. Watch him try to logic his way out of destiny while the volleyball gods line up the slowest, most agonizing character arc imaginable.

No, he doesn't get a tragic backstory.

No, he doesn't want to win Nationals.

Yes, he will still end up on a team.

Because this isn't his story.

It’s mine.

And I’m going to make him love volleyball again if it kills us both.

Don't read, Thanks for read.
