It all started with a rock. A normal rock. Kicked by a random time traveler and that same rock rolled into Hinata's foot. And suddenly the universe defied logic. Hinata freezes time for one second. Then two. Then three. Then ten. Now every spike is a reality-breaking event, every jump is a glitch in the universe, and every anime universe is panicking like they got a notification from God. Aizen is confused. Gojo is entertained. Akashi is malfunctioning. Isagi is on the floor. Ukai is stressed. Hinata is smiling. And the mysterious traveler who caused all this? He's hoping no one ever finds out. This is a multiversal crackfic where volleyball breaks physics, timelines collapse, and one boy becomes the most dangerous being alive. #1 in Coachukai as of August 9th 2026 at 12:42 p.m DISCLAIMER/COPYRIGHT NOTICE: I do not own any character or world from Haikyuu, Jujutsu Kaisen, Bleach, Blue Lock, Kuroko No Basket, or any other series mentioned.

Erity Sawamura played volleyball in America for a short amount of time, labeled one of the best Libero's in the country. Every play she made, every touch of the ball was satisfactory for her. Her second year of middle school, she lead her team to victory in nationals. By the end of the year, she received a call from her family in Japan about her fathers death, so she decided to move back to Japan along with resigning from her spot on her team. Now, a couple years later, she would start attending Karasuno High as a first year along with her older brother who was a third year. (Various haikyu x oc)

Everyone on the Kurasuno Volleyball team knows about the spark between their setter, and middle blocker. So, they give them a push. In the wrong direction of course They had decided to make a betting pool, to see who'd confess first. But things don't go according to plan when Hinata and Kageyama figure out about what's going on. And they're not the happiest pair around when they do.

When a letter from Kyoto arrives at Karasuno, Coach Ukai doesn't expect much. Just a harmless practice match, right? Except... the team has zero match history. Their coach knows Grandpa Ukai. And their Olympic record is terrifying. Karasuno accepts the challenge - but who exactly is Aokure High?

Honestly I haven't decided where this story is gonna yet lol but it'll be good I promise :)

Y/N returns to her hometown in Miyagi, Japan after spending a good decade after high school traveling the world. Once she is all settled in she sets out looking for a job. Walking around town she stumbles upon a flyer looking for a coach assistant for the Karasuno's boys volleyball team, after some brainstorming she decides to take to the job. However, by picking this job she could have never imagined the crazy experience she is about to go through, and the amounts of buried memories from the past resurfacing.

Your friend is assistant coach at the karasuno high school, home of the flying crows. He's got to tend to his mother and doesn't want to leave the coach alone. I mean of course he needs an assistant coach. Well lucky for you you've got the skills. Playing volleyball in school wasn't for nothing. You need to find something to pass the time anyway so why not do it? Well turns out this coach is actually your crush from high school and he's just as annoying as he was before

Keishin and Y/n have known each other for what feels like a lifetime. Since both their parents were close friends they got to grow up with each other. Y/n and Keishin remained close friends even after highschool and knew a lot about each other, but not everything... something from their past was going to encourage one of them to make their move.
