Karasuno High School was formally two different schools, one reknown for the heroes that graduated from there, the other for the old powerhouse volleyball team. Both schools had converged several years ago. But, this year comes with a surprise, a group of 30 students facing unmanageable odds. On one hand, the class faces off with villans, protecting innocent lives along with themselves. The other, rebuilding the volleyball team, of which 10 participate in. That's what happens when you have 7 members of a particular family in one school, a fun-filled chaotic year.
