The battle for the rings had just begun when Tsuna, from ten years in the future, suddenly arrived from the future. It turned out that the future world had undergone a massive upheaval, and all of Tsuna's guardians had betrayed him.

To free his companions from their shackles and confront the enemies of the future world, Tsuna decides to recruit Xanxus and Byakuran from this era to his side. Unexpectedly, Tsuna awakens a treasure chest system. By following the system's instructions and arriving at designated locations on time, he can open treasure chests and receive rewards.

Arrive at Namimori Middle School, open the S-rank treasure chest, and be rewarded with seven types of Dying Will Flame!

Arrive at Namimori Shrine, open the SS-rank treasure chest, and be rewarded with the strongest box weapon—the Auspicious Cloud Kirin!

Arrive at Chrome's boudoir, open the SSS-rank treasure chest, and be rewarded with a reverse breakthrough to the pinnacle of Dying Will!

Arrive at Fran's hometown, open the SSS-level treasure chest, and be rewarded with the tenth type of Dying Will Flame - Void Flame!

Who would understand! Transmigrated into the world of Prince of Tennis, the orphan Rinji Kanzaki not only has money and an apartment, but also carries the lingering soul of a DNF Elementalist! He knows that Seigaku has Tezuka, Hyotei has Atobe, and Rikkai has that "Child of God" Yukimura—but that doesn't stop him from secretly rolling around since elementary school: old YONEX rackets wrapped in black straps, bandages hidden in his cuffs for extra practice, and obsidian earrings that represent his obsession with "adulthood".

Once he entered Rikkai, he transformed from a "Gray Feather Falcon" into a "Silver Tyrant": 175cm tall with shoulders as broad as Sanada's, his team uniform open, revealing an old scar on his collarbone, he tossed a coin from another world before matches to determine his serve, and his wristbands embroidered with "King's Gambit" were a blatant provocation. While others played with spin, he played with elements: lightning-enhanced defenses, ice walls locking down half the court, and with a single placement of a void ball, all the opponent's balls were sucked away to the landing point he desired!

A former key server for a university volleyball team accidentally travels to the world of Haikyuu Shonen and restarts his life. This time, he is no longer willing to be that unknown key server. He becomes the team's ace, the absolute main force in the hearts of his teammates, and leads his teammates from Karasuno to dominate the country!!!

[Hot-Blooded High School + God-Level Choice + Hot-Blooded District + Landlady + Gangster Daughter + Chaebol Princess +…]

In his previous life, Ryuzaki was a powerful gang leader, but he was treated like a dog by the consortium, discarded after being used, and his body was sunk in the bay.

After being reborn, he became the weakest punching bag in Suzuran High School, and the beginning was a suicide scene?

It doesn’t matter, the god-level selection system is activated!

[Option 1: Knock down the thug who came to provoke you with one punch. Completion Reward: Physical recovery, Strength +10!]

[Option 2: Endure silently and leave. Completion Reward: Earn the title "Ninja Turtle"...]

Do I even need to choose?

From dominating the lily of the valley and stepping on the hibiscus, to integrating Kabukicho and annexing the Yamaguchi-gumi...

Standing on the top of Tokyo, Ryuzaki Shin said calmly, cigarette in mouth:

"My rules are the only rules in Tokyo!!"

Tennis genius Ye Feng traveled to the world of Prince of Tennis. From then on, the world had a legend of a great devil.

He possesses an unrivaled body, strength beyond the limit, and an all-conquering spirit!

The five senses, the realm, the state of selflessness, the limit of repeated tempering, the limit of brilliant talent, the limit of perfection! Ashura Shinto!

Countless special moves will become even more powerful in his hands!

He knows what you know, and he has what you don’t have!

There is no strongest Ye Feng, only a stronger devil!

Starting from Rikkai University, Ye Feng's name will be imprinted in the Ganges of history!

Originally just a regular sports anime fan on Earth, he suddenly finds himself transmigrated into an anime world. Awakening the template of Akashi Seijuro, he initially believes he has entered the world of Kuroko no Basuke.

But it isn’t until he hears the name of the man standing at the very peak of the world that he realizes—this is the realm of killer tennis!

He acquires Fudomine Middle School, establishes a brand-new tennis club, and gathers all the top-tier players from the junior high world. Using the power of the template system, he accelerates each player’s growth.

Through that, he leads them to a three-time national championship victory and onto the U-17 world stage
