Tokyo and Kyoto Jujutsu High hold a Goodwill Event annually as a competition between the two schools. It is held early in the school year during the spring before the busy season in the summer.
The Goodwill Event lasts two days with each Principal choosing an event for the day. However, in the past years, both Principals have agreed on the same pattern; team battle on the first day and individual battles on the second.
The event is considered to be a jujutsu battle where the only rule is no killing one another. All jujutsu is permitted in battle as well as the usage of cursed tools.
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.
