Jujutsu Kaisen, Vol. 1, by Gege Akutami
Gege Akutami’s Jujutsu Kaisen is an on-going Japanese horror manga; it’s been serialized in Shueisha’s Weekly Shōnen Jump since March 2018. Volume one collects the first seven issues.
Exemplary athlete Yuji Itadori declines to join any of his high school’s sports teams. After all, this would mean leaving the Occult Research Club. Itadori isn’t especially interested in the occult, but the club (at least one club is a mandatory activity) doesn’t insist on actual attendance, which gives him time to spend with his dying grandfather. As well, the club has but three members — Iguchi, Sasaki, and Itadori — and without him, it would dip below the minimum membership threshold for a school club and be subject to summary disbanding.
Which, as it turns out, would have been a good thing for Iguchi and Sasaki.
