April 23, 2026, Tokyo, JAPAN – COVER Corporation (Minato-ku, Tokyo; CEO: Tanigo Motoaki) is pleased to announce the release of “Inatsu -伊夏-” Season 2, a special collaboration project between hololive English -Myth- member Ninomae Ina’nis and SAKEBOYS. This project continues the journey of exploring the world of Japanese sake together with fans, sharing new discoveries, experiences, and appreciation for traditional craftsmanship.

The key focus of Season 2 is yeast — an essential element that shapes the aroma and character of sake. Inspired by the idea that yeast can create fruit-like fragrances in sake, Ninomae Ina’nis participated in tasting multiple trial brews and selected a yeast profile that highlights a gentle and elegant pear-like aroma.

The sake is carefully brewed by Seto Shuzo in Saga Prefecture, using traditional methods and locally-developed yeast.
