[Giving the sports anime world a little taste of the Jujutsu Kaisen set]
At the start of a new school year, a countdown System suddenly appeared before Nanase Wakanight.
When the countdown reached zero, he transmigrated from a world where Gojo and Geto were both teachers at Jujutsu High into the original Jujutsu Kaisen timeline.
His stay could be long or short, and when he returned to his own world, the countdown would appear again.
First transmigration
Nighttime, the collapsed school building of Sugisawa Third High School.
Gojo Satoru, who said he'd turn back in ten seconds; Itadori's body, possessed by Sukuna; and Fushiguro Megumi, covered in wounds.
Nanase Wakanight appeared out of nowhere, clutching a volleyball, and froze. "Are they filming a movie?"
The very next moment, he nearly got taken out by Sukuna's slick combo.
Second transmigration
Daytime, Harajuku.
The first-years and Gojo-sensei were waiting for Kugisaki Nobara to join them.
Noticing someone was missing, Nanase Wakanight asked, puzzled, "Where's Geto-sensei?"
...As he continued transmigrating back and forth, Nanase Wakanight discovered he could bring people along.
So on the Xth transmigration, the original timeline gained one Gojo-sensei and one Geto-sensei.
