Ten Shadows Technique, but I Summon Tailed Beasts

Uchiha Chinagi had been born with a frail constitution in his previous life. He died just after turning ten, then woke up in a place called the Zenin family, reborn as an eight-year-old child.

The new world still followed the rule that the strong preyed on the weak, and the Zenin family was so rotten it made him sick.

Chinagi, now blessed with a healthy body and still carrying Uchiha blood, burst into wild laughter: "I'm awake. It's hunting time!"

--

A monster was born into the Zenin family.

At eight, after someone insulted him at a banquet, he jumped onto the table and used a fireball to burn off everyone's hair.

At nine, he awakened a visual jutsu called the Sharingan, instantly making a name for himself and shaking the jujutsu world. He even declared that he would rename the Zenin family the Uchiha family.

At eleven, he summoned a tailed beast made of sand, and a towering wave of sand swallowed the Zenin family.

At thirteen...

At sixteen...

The power Chinagi awakened in his Sharingan was unlike anything his clan had seen. He could copy the remnants of tailed beasts and project them into this world.

Well, what was there left to say?

He stormed into the Jujutsu Headquarters. "You old geezer, it's about time you let me have a turn in that seat." Today, he, Uchiha Chinagi, was going to rule the jujutsu world. Who agrees? Who objects?

What? Someone objects? Then they can take it up with his one, two, three... nine tailed beasts!

One day

Chinagi: "I'm going to create a world with nothing but little flowers."

The higher-ups and the mafia panicked. "Who's Little Flower? Who killed Little Flower? Get out here!"

Gojo: "Little Flower is his cursed spirit 'best friend.'"

The higher-ups: ...

The mafia: ...

Who provoked this mad dog now?!

*

Just when the curse spirits, having planned for every contingency, thought their scheme had finally succeeded, they saw a black-haired boy standing atop the Ten-Tails, covering his scarlet eyes as he laughed wildly. "Our roles have switched. Now I'm the final boss you have to fight!"

What? You thought I was the protagonist who challenges the villain? Wrong! I'm the final boss you have to challenge!

Gojo Satoru had a problem lately. A genius had appeared among his peers. All he'd done was accidentally kill the other boy's cursed spirit friend, and now the genius kept showing up every day, calling him things like "archenemy" and "revenge," all so they could hang out (fight). Sigh, what a headache.

Chinagi's archenemy +1

Best friend +1

Archenemy +1

Best friend +1

Gojo: "Wait... aren't I your one and only archenemy, best friend, destined companion, and lover?!"

Chinagi: "Did something weird sneak in there?"

Coming soon: Cosplaying Sakamoto and Transmigrating into Haikyuu!!

Blurb: One day, Oikawa Tooru saw transfer student Sakamoto escape a gang of delinquents chasing him by leaping straight from the first floor to the second, without using any external support.

He was so shocked that he dropped his drink. "That incredible jumping power! He's clearly a promising player for our volleyball club!"

He swiftly recruited him, and everyone discovered that this total beginner picked things up incredibly fast. He could play libero, outside hitter, opposite, or setter, and excelled in every position.

Damn genius!

All the top volleyball schools knew that Aoba Johsai had gained a genius with all-around skills, an absolute beast and a volleyball star. No one doubted his ability, but whenever his name came up, everyone wore a very complicated expression.

"Sakamoto, huh..."

"Every time he receives or hits the ball, he strikes a sparkling, perfect pose. The shrieks from the audience are about to burst our eardrums."

"During technical timeouts, everyone else is resting and recovering, but he crosses his legs and reads a book while sitting in midair, without a chair!"

"Every time practice ends, before I can even react, he's already put a drink in my hand and wiped the sweat from my face!"

"He can even massage four people at once!"

"He even helped me dry my shoes!"

"Playing volleyball, eating, running, diving... Whatever he does, every gesture and movement is the height of elegance!"

Teammates and opponents, through gritted teeth: "I've never seen anyone show off so much."

Still the teammates and opponents: "But... he's so cool!"

After cosplaying Sakamoto and transmigrating, every day he was either completing the System's assigned show-off missions or practicing how to show off with elegance.

At night, he secretly washed piles of identical clothes, just so he could change into a fresh outfit whenever he practiced, staying dry and sweat-free.

He bought a pile of mannequin heads to practice wiping the sweat off several people at once. He practiced running along walls and leaping across rooftops so he could catch every balloon blown away by the wind. He studied how to look handsome from every angle when receiving or hitting the ball...

Oikawa: "Why not put all that effort into volleyball?!"
