Overview
Blue Box Season 2, originally Ao no Hako 2nd Season, is the second season of the series adapted from Kouji Miura's manga. It blends romance, slice of life and sports, and studio Electric Circus produces it as a TV anime. The schedule lists the premiere as 4/10/2026.
OtaHub's take
Daisuke Sakou directs, Yuuko Kakihara handles series composition, Miho Tanino designs the characters, Anri Ishida is the art director and Narumi Konno handles color design. This continues Ao no Hako, so the first season is where to start in order to follow the relationships and emotional shifts built up earlier.
Verdict
It suits viewers who like gentle romance set against the world of sports, especially those who finished season one and want to see where the story goes. Newcomers should watch the first season first.
