[Main character is a bad boy + overpowered + pure black-hearted heir to the brewery + follower of the Yukimura cult + ensemble cast + chat group] This is written by a Yukimura fanatic.

This is a crossover of anime, primarily Prince of Tennis and Detective Conan, with Prince of Tennis as the main focus and Detective Conan as a secondary focus. It also includes some other crossover anime.

Privately set up mountains of competition novices

When Karasuma Gaki first saw Yukimura Seiichi at the club when he was 4 years old, he decided to join the family.

Unexpectedly, he learns that he is actually the grandson of the villain Karasuma Renya, and is tasked with stealing the protagonist's spotlight.

At the age of 6, he was forcibly taken away from Yukimura by Karasuma Renya and raised by Gin, where he grew up under Gin's severe beatings.

No way, he's the tennis prince, he wants to go back to playing tennis!

He returned to Japan and enrolled at Rikkai University with Yukimura Seiichi, beginning his fantasy and magical tennis journey.

One ball shattered the wall, giving his father a glimpse of the wonders of tennis.

Tennis prodigy Karasuma Gaki juggles tennis training with his duties at the sake brewery.

Vermouth and Kaito Kid are drooling over Niou; they both want to learn Phantom!

Angels and silver bullets? Spell interruption! No traitors allowed in the brewery!

Bourbon is a loyal fan of Rikkai University!

Out of consideration for Bourbon being his fan, Karasuma decided to spare his life, brainwashing him daily to make him understand that his lover was the organization! Not Japan!

Shuichi Akai defected? We'll catch him, drug him, and turn him into a little brat. Let's see how he runs wild then!

After being ambushed and shrunk by a drug, Shinichi Kudo finds himself in another world. There's already a 17-year-old Shinichi Kudo here... *sobs* He's just a drifter in this other world; his current name is Shinji Kudo. ಠ╭╮ಠ

Keigo Atobe's twin brother, who adores his older brother (pure brotherly love!). The story follows the growth of a sporty young boy, initially focusing on slice-of-life, then transitioning to the Prince of Tennis main storyline, a crossover anime plot, and possibly a Haikyuu!! main storyline later on. It might even go off on its own, though I'll try my best, but it's still undecided. The main pairing is Yukimura, and it's unlikely to change unless something unexpected happens... well, we'll see. Also: the romance will develop in the later part of the main story, and it will be slow-paced and gentle, not dramatic. If you're expecting a sweet, lovey-dovey romance from the start, please ignore this. The protagonist isn't that kind of character; the kind who dominates the world with tennis is out of the question. This protagonist won't just be involved in one sport club, as I want to incorporate elements from several anime. It will be more slice-of-life. Note: slice-of-life, please don't ask me why he doesn't dominate the world, he won't. Due to work, I'll try my best to maintain consistent updates, occasionally taking days off to update around 6,000 words a day, and I'll try to keep it stable to avoid abandoning the project. Please support me! As usual, I'll patch up any regrets I can, but there's nothing I can do about those. This story doesn't follow logic, so please just enjoy it.
