Tennis in an Unscientific World

Completed: Muichiro Plays Tennis

Muichiro's past life as the Mist Hashira of the Demon Slayer Corps belonged to a previous incarnation.

In this life, Muichiro got into Rikkai University with excellent grades. At his deskmate's recommendation, he joined the tennis club, where he saw tennis that could burst into flames and rob people of their five senses.

After returning home, Muichiro started blowing into a gourd, much to his older brother's confusion.

Tennis is dangerous. He has to get stronger so he can protect himself and the people around him.

#Shockingly, one glance was enough to make Muichiro pick up his breathing techniques again

Had he encountered a demon?

No, he had only watched a match.

Story blurb:

Uehara Haruki had known since childhood that this was an unscientific world. After all, it was overrun with monsters. But that was fine, as long as the people around him were normal.

Until one perfectly ordinary day, Uehara Haruki went to watch a tennis match at the national tournament and witnessed tennis skills that seemed even less scientific than monsters.

Things like Blazing Inferno, Waltz of Destruction, and taking away all five senses. Was this really the tennis he knew? Could a human really hit a ball like that? Everyone around him seemed to take it for granted and didn't notice anything strange. Uehara Haruki even began to wonder if he was making too big a deal of it.

Later, he came to understand. In this unscientific world, tennis like this was perfectly reasonable.

After all, this world was unscientific to begin with, and anything could happen. When Uehara Haruki found an egg in his bed the next day, he was once again certain this world was unscientific.

Notes:

1. I'm a huge Rikkai fan. Rikkai will win three consecutive championships without a single weakness.

2. The Captain is the strongest.

3. Haruki will gradually grow stronger. His golden finger is that egg.

4. I've only watched the anime. The characters belong to the original work; any OOC is my responsibility.

5. Probably no romance in the main story.

6. Haruki's CP is, of course, Little Seaweed.

Currently serializing: The System Won't Let Me Slack Off

Tsukiyama Kazuya died, then came back to life.

The System bound to him told him that he could survive if he collected enough popularity points.

And so, a billionaire suddenly appeared in Yokohama. People heard that he had bought ten publishing houses to publish his own novel. Curious onlookers stared at the familiar names in the newly published book, deep in thought.

What do you do when your favorite teacher is incredibly rich?

Tsukiyama Kazuya looked at his maxed-out charm stat, then down at the middle-aged man hugging his leg and weeping, insisting that he debut as a performer. He made up his mind.

A month later, the people at Jujutsu High stared at a group of fanatical cursed spirits, training in perfect formation while waving Tsukiyama-SAMA support flags, and questioned their lives.

And so, the filthy Tsukiyama Kazuya shouted, "Die!" and sliced the Hand Demon in half with a look of disdain.

In recent years, the Demon Slayer Corps' conditions have visibly improved, and it's all thanks to the Tsukiyama family.

The Tsukiyama family: As long as it's something Kazuya wants, we can give it to him.

Damn, I'm so jealous!

Young master Tsukiyama, whose dream was to save the world and who had just chopped down a demon, looked at the sudden huge increase in his popularity points: ???
