Blue Box Season 2 trailer brings back Chinatsu’s resentful former teammate

The new Blue Box Season 2 trailer introduces a resentful former teammate of Chinatsu while confirming the season’s 2 theme songs and its October 4 premiere. Crunchyroll News published the trailer on August 26, 2026, in the official announcement.

2 songs set the tone for Season 2

• Opening theme: “Anata no Hana no Iro” by aiko.
• Ending theme: “blue in” by elsewhere kikou.

The Crunchyroll News announcement confirms both tracks alongside the new visual and trailer footage. That gives the season a defined musical identity before release, although the announcement does not provide further details about how the songs will be used beyond their opening and ending roles.

Chinatsu’s sporting past becomes a new source of conflict

The footage brings back one of Chinatsu’s former basketball teammates. He holds a grudge against her, making his return the central conflict highlighted by the trailer.

The reason for that resentment and its consequences are still undisclosed. What the footage does establish is that Season 2 will expand beyond the relationships already in place: Chinatsu must also face someone connected to an earlier part of her sporting life.

Daisuke Sato takes over direction

Daisuke Sato directs the season at Electric Circus, replacing Yuichiro Yano, who was previously associated with directing at Telecom Animation Film.

Yuko Kakihara remains responsible for series composition, while Miho Tanino returns as character designer. full official publication brings together these staff credits, the new visual and the 2 confirmed songs.

The director change is the main documented staff renewal attached to this announcement. It signals an evolution in production, but it does not by itself establish that the series’ visual style or pacing has changed; that will require more material from the season.
