What is New With Blue Box Season 2?
The latest Blue Box season 2 update includes a new main trailer, main visual, and the reveal of both theme songs. Together, the new previews offer a closer look at Yumeka Kido’s role, her history with Chinatsu Kano, and what lies ahead for Taiki and Chinatsu.
What Does the Blue Box Season 2 Trailer Reveal?
The Blue Box season 2 trailer focuses heavily on Yumeka, Chinatsu’s estranged former basketball teammate. It opens around Yumeka quitting basketball and her bitter feelings toward Chinatsu, who continued pursuing the sport and her dreams after they stopped playing together.
The trailer gives their history more context through Taiki Inomata, who recalls Chinatsu practicing early in the morning during middle school because she wanted to catch up with Yumeka. Chinatsu is also shown wondering how things might have been different if Yumeka had stayed on the team, while Taiki hopes the two can reconcile.
The focus eventually shifts back to Taiki and Chinatsu and the romance at the center of the series. VIZ Media, which publishes the official English version of Koji Miura’s manga, describes its premise: “Taiki admires Chinatsu from afar, but he doubts that she sees him in the same way.”
Near the end of the new trailer, Taiki signals another important conversation when he says, “There’s something I want to talk about.”
