The Demon King's Five-Part Sports Boyfriend

[There is a terrifying Demon King in this world, powerful enough to destroy it. No one knows how he came to be, but if he discovers that he is destined to become the Demon King, he will definitely destroy the world!]

Somehow, this premise suddenly appeared in Saiki Kusuo's worldview.

To protect this world (and its coffee jelly), the godlike psychic Saiki Kusuo decides to go undercover beside the Demon King, so he can stop him from turning evil at a moment's notice.

The road to saving the world is long and arduous. Today, too, is a peaceful d

Kaido Shun: Amamiya, become my ally! The same blood flows through you and me. My Dark Force is surging! The Jet-Black Wings!! Awaken!!! (BGM playing)

Amamiya Mao: Aaaaaah, no chuunibyou, no chuunibyou!!

Kaido Shun: Huh?! QAQ!!

Saiki Kusuo falls silent as he looks at Amamiya Mao, who has yet to become the Great Demon King.

[I absolutely can't be human in this world!]

Mao has felt this way since childhood. In a world where everyone has colorful hair and certain characters even come with their own BGM, he's just too painfully ordinary! Damn it!

To keep his ordinariness from being too obvious, Mao decides:

1. Make himself less noticeable and stay away from anyone conspicuous.

2. Befriend Saiki, the unremarkable ordinary guy in his class.

3. Fall in love with a boy who has black hair just like him!

After unexpectedly getting his hands on a local gay dating app, Mao finally meets his one true love.

This ordinary black hair! This ordinary M-shaped fringe! These ordinary blue eyes! He's a perfect match for an ordinary guy like me!

However, he has no idea that he has unwittingly transmigrated across worlds over and over, and that he's a super eccentric, hopelessly face-blind person.

Flash! Go watch my boyfriend's volleyball match!

Flash! Go watch my boyfriend's soccer match!

Flash! Go watch my boyfriend's swimming match!

Flash! Go watch my boyfriend's baseball match!

Flash! Go watch my boyfriend's... match!

After rushing around to watch her boyfriend compete in five events in two days, Mao is deeply shaken: Saiki, did you know? I think my boyfriend might be an all-around sports genius...

Saiki Kusuo, who followed him to all five events to stop him from awakening: ... I can't say whether your boyfriend's an all-around genius, but thank goodness you're an idiot.

A little romantic comedy.

Expected victims: Kageyama Tobio, Isagi Yoichi, Nanase Haruka, Furuya Satoru

The last one is still undecided, because the author is waiting for OVERTAKE.

Saiki is my bro, and my boyfriend is a black-haired guy with an M-shaped fringe (???)
