On one particular day, Utsu Shinji was hit and sent flying by a passing truck as he was heading out.
When he woke up, he had been reborn in a new world. Utsu Shinji always thought he would live out this life in peace.
That was until one day he realized that, after transferring to Miyagi, he was holding an acceptance letter from Aoba Johsai.
Utsu Shinji tried to reassure himself that maybe someone else just had the same name, but then he saw Tōru Oikawa and Hajime Iwaizumi walk past him.
He tried reassuring himself again that maybe they only looked alike and shared the same names. Then one day, during his morning run, he saw Wakatoshi Ushijima.
He searched online and found Miyagi's Karasuno, Shiratorizawa, Johzenji, and Tokyo's Nekoma, Fukurodani, Inarizaki, and more.
Only then was Utsu Shinji finally willing to face reality: I'd really transmigrated into the world of Haikyuu!!? Aaaaaah??
