Tokyo and Kyoto Jujutsu High hold a Goodwill Event annually as a competition between the two schools. It is held in the middle of the school year after the busy season for jujutsu sorcerers in the summer.
The Goodwill Event lasts two days with each Principal from their respective school choosing an event for the day. However, in the past years, both Principals have agreed on the same pattern; a team battle on the first day and individual battles on the second. This tradition was broken by Satoru Gojo in 2018, who made it so the competition ended with two team competitions.
Normally, second and third-years participate but first-years can be permitted with their senpai's permission. Although Jujutsu High's curriculum is four years long, students can only participate up to their third year.
