Nioh Reborn to Save the World (All Nioh)

Not long after winning the Best Actor award, Niou was reborn at the moment he first entered Rikkai Junior High. At the time, he had not yet retired because of his injuries.

In this life, he gained a System. By completing missions, he could train in different worlds, allowing his own world to break free from its predetermined fate and change its original ending.

He was already twenty-five before being reborn, so he showed his former teammates an incredible amount of patience. If only the System's missions weren't so strange.

For example: maintain skin contact with Sanada for five minutes; say five sincere compliments to each of Rikkai's regulars; go on cross-dressing dates separately with Byodoin Phoenix and Tanegashima Shuji.

Niou: ?

P.S.:

1. The whole story is already written, but updates will probably take a long time because I'm lazy. You can bookmark it for now, babies.

2. Includes: Kuroko's Basketball, Katekyo Hitman Reborn!, Touken Ranbu, Detective Conan, Hunter x Hunter, and Brothers Conflict.

3. Rikkai will win three consecutive championships without a single weak spot. I won't bash any characters, but fans of Seigaku may want to skip this. Our stances and ways of looking at things are different, and neither of us would be happy.

4. My writing is limited, so the matches may not be as exciting as you expect. I'm genuinely bad at writing sports matches, and they aren't the focus of this story. Many will be glossed over, though I'll give a few important ones more attention.

5. No CP, but everyone is into Niou. It may feel like he's too much of a Mary Sue, but with everyone into Niou, some characters will inevitably be out of character.

Pairings include Yukimura/Niou, Sanada/Niou, Yanagi/Niou, Yagyuu/Niou, Kirihara/Niou, Tanegashima/Niou, Byodoin/Niou, and Atobe/Niou. I might also write about a few other handsome guys, but not anyone from Seigaku (I might consider Echizen Ryoga).

There will also be some crack pairings with characters from other worlds.

Some will have the slightest hint of something beyond friendship, while others will simply be one-sided crushes. It depends.

6. The extras may include short stories for some pairings, as well as watch-along chapters (I really want to see characters from other worlds fighting for attention).

7. Not recommended for readers who like to scrutinize canon details. It's been a long time since I last read Prince of Tennis, though I will look things up.

8. Other possible deal breakers may be mentioned in the author's note for the first chapter.

Theme: Perseverance is a fine virtue.
