Instead of rejecting him, his classmates fight alongside him, showing that the school's real concern is protecting the town of Makochi from harm—hence why the students call themselves Bofurin.

While attending university, he submitted a dark fantasy work titled Uramare-ya for a newcomer award and then achieved a Kodansha-published serialization with the gender bender/sports manga Danshi Bado-Bu ni Joshi ga Magireteru Secret Badminton Club.

When a second badminton series stalled in development and after he received some advice from an editor, Nii shifted his focus to creating stories about male characters he called "cool boys" (カッコいい男の子, kakkoī otokonoko).

[15] Wind Breaker was born out of Nii's desire to create a series centered around this archetype, which he wished to accomplish by studying similar works while consulting with an editor.

However, he was unable to make progress with the team leader of Bofurin as the protagonist, so he brought in Sakura to fill the role to lend an outsider's perspective on the story's circumstances.

[15][16] The author has called Sakura his favorite character for embodying the "cool" factor he sought to accomplish and for the time he devoted to designing his appearance and personality.

[16] Also feeling that he lacked the personality of a main character in an early draft, Nii gave Sakura the tsundere-like trait of being embarrassed when someone praised or thanked him.

[58][59] It is directed by Toshifumi Akai, with scripts written by Hiroshi Seko, character designs by Taishi Kawakami, and music composed by Ryo Takahashi.

[60] The series aired from April 5 to June 28, 2024, on the brand new Super Animeism Turbo programming block on all JNN affiliates, including MBS and TBS.

The cast features Ryoga Ishikawa as Haruka Sakura, Hiroki Sana as Hajime Umemiya, Shunichi Takahashi as Tōma Hiragi, Yūto Andō as Hayato Suō, Taiga Nakamoto as Kyōtarō Sugishita, and Kazan Yokoyama as Akihiko Nirei.
