A new main trailer and key visual for Blue Box Season 2 put Chinatsu’s dilemma at the center of the campaign. The materials show her past with a former teammate, her life under the same roof as Taiki, and the winter pressure of national-level competition colliding at once. The sports romance returns to Japanese television on October 4, framing a colder, more unsettled stretch after the measured pace of the first season.
The main trailer spends much of its runtime on Chinatsu’s uneasy reconnection with former teammate Yumeka Kido before turning back to her relationship with Taiki. Practice drills, winter streets, and clipped conversations hint that club pressure and private emotion will collide as the pair try to keep living under the same roof. The preview also unveils the season’s theme songs, with aiko performing the opening Anata no Hana no Iro and elsewhere kikou performing the ending blue in.

The Blue Box Season 2 main visual was also shared alongside that preview, and the art is almost entirely Chinatsu’s. She lies in falling snow in a pale coat and scarf, staring toward the viewer with bright, unwavering eyes against a washed-out winter backdrop. The still matches the trailer’s seasonal shift and presents her as the figure the new season intends to follow most closely.
The sequel also arrives with a reshuffled production team. Daisuke Sato, whose credits include Lupin ZERO, now directs at Electric Circus after Yuichiro Yano handled the first season at Telecom Animation Film. Series composer Yuko Kakihara and character designer Miho Tanino are both staying on, which should keep the scripts and character look aligned with the earlier cour.
What is Blue Box Season 2 about?
Koji Miura writes and illustrates Blue Box, a sports romance that started as a one-shot before beginning serialization in Shueisha’s Weekly Shonen Jump in April 2021. The manga blends coming-of-age romance with badminton and basketball at Eimei, a junior and senior high school built around competitive clubs. Viz Media publishes the official English edition and describes the setup this way:
Taiki admires Chinatsu from afar, but he doubts that she sees him in the same way. Yet somehow, he musters up the courage to tell her to never give up on her dreams! After such a bold declaration, will Taiki’s fleeting high school romance finally begin
Season 2 continues after Chinatsu has moved in with Taiki’s family because her parents transferred overseas, a living arrangement that still shapes every awkward morning and late-night talk. The new arc leans on her unfinished history with Yumeka, an estranged former teammate whose return needles Chinatsu about basketball, dating, and whether she has let her focus slip. Winter training, a date that does not stay private, and the approach of the Winter Cup force her to sort out what Taiki means to her while both of them keep chasing nationals.
Blue Box Season 2 lands on TBS and its affiliate stations in Japan on October 4, with Netflix rolling out the new episodes internationally in the same month. Japanese distribution lists also place the series on Disney+ in select regions, giving viewers multiple platforms to follow Chinatsu and Taiki through the colder stretch of their high-school years.
