Hirayasumi Anime Adds Gen Hoshino as Opening Theme Performer

Hirayasumi’s official website announced Monday that Gen Hoshino will sing the television anime’s opening theme. The announcement did not name the song.

The adaptation of Keigo Shinzō’s manga will debut in Japan on NHK General in January 2027. Viz Media has also announced an English release in 2027.

TOMOO will perform the ending theme, “Fūmizekka” (Delicious Flavor).

Viz Media and Japan Society held the first episode’s world premiere screening on October 7 at Japan Society’s New York City location.

The anime’s cast includes:

• Yūma Uchida as Hiroto Ikuta
• Mayu Takahashi as Natsumi Kobayashi

• Yōko Hikasa as Yomogi Tachibana
• Yume Miyamoto as Akari Yokoyama

Viz Media describes the human drama as following Hiroto Ikuta, a carefree 29-year-old without a girlfriend, full-time job, or future plans. He is happy with his life, believing that slowing down can help people move forward.

Others struggle to understand his outlook. Around him, people navigate anxiety, confusion, and grief as they try to figure out life.

Hiroto unexpectedly inherits a house and complicated emotions after befriending a grouchy elderly neighbor. His 18-year-old cousin, Natsumi, moves in. A struggling art student with troubles of her own, she may test his easygoing lifestyle.

Shinzō launched the manga in Shogakukan’s Weekly Big Comic Spirits in April 2021. Shogakukan published volume 10 on April 30. The series has over 1.1 million copies in circulation worldwide and will end on November 16.
