The upcoming romantic comedy anime Tenbin has released its third teaser promotional video and a new teaser visual. Both materials showcase the start of the school year amidst blooming cherry blossoms, setting a distinctly spring atmosphere. The tagline accompanying the visual reads, "Another season without you has come around."

The story follows Hayato, who transfers to a city high school and reunites with Haruki. Hayato remembers Haruki as a childhood friend he believed was a boy, only to discover Haruki is now a girl. The anime stars Ikumi Hasegawa as Haruki Nikaidō and Shunichi Toki as Hayato Kirishima. Other cast members include Miharu Hanai as Himeko Kirishima, Natsumi Haruse as Minamo Mitake, and Fūka Izumi as Saki Murao.

Chuan Feng Xu is directing the series, with Deko Akao handling series scripts. N-Nei Kurahashi is responsible for character designs based on Siso's original illustrations. The music is composed by Ryosuke Nakanishi, Naoki Tani, and Yuri Morita, with Pony Canyon producing. The opening theme, "Natsu ni Kasanete," is performed by the group Dialogue+.

Tenbin is set to premiere this July on Tokyo MX, BS Fuji, and other networks. The anime adaptation of Yu Hibari and Siso's light novel series was initially announced in September 2023.
