The Japanese‑American family band Bless4 announced on their official X/Twitter page that lead singer AKINO will be graduating from the group after a 24‑year run. In tandem with her departure, the quartet – now reduced to three members – will continue under the new moniker bless∞(Forever), signaling a fresh chapter for the siblings.
AKINO’s Impact on Anime and Game Music
AKINO first entered the music scene alongside her brothers Akashi and AIKI and sister Kanasa with the debut single “Good Morning! Mr.Sunshine.” Her breakout solo moment arrived when she provided the opening theme “Genesis of Aquarion” for the Genesis of Aquarion series, a track composed by the acclaimed Yōko Kanno (Yōko Kanno). The collaboration proved a springboard, leading to a string of anime‑related songs such as the energetic “Go Tight” (also for Aquarion), the vibrant theme for Oban Star‑Racers, and the upbeat opening for Kantai Collection (news). Her voice has also graced titles like Active Raid, Amagi Brilliant Park, and even the popular MMO Final Fantasy XIV.
Band History and Recent Line‑up Shift
Formed in 2003, Bless4 is comprised of four siblings from the Kawamitsu family, who grew up in Phoenix, Arizona before settling in Kawasaki, Japan. Over the past two decades the group has contributed music to a variety of anime projects, including Disney’s Stitch!, the historical fantasy Izetta: The Last Witch, and the supernatural series The Ancient Magus’ Bride. Their eclectic discography has helped them build a loyal fanbase both in Japan and abroad, with tours in Korea and releases across Europe.
In 2022, brother AIKI (AIKI) announced his exit to focus on family matters and a solo career, reducing the group to a trio. The latest announcement marks the second major personnel change, with AKINO’s graduation leaving only Akashi, Kanasa, and a supporting lineup.

The remaining members explained that the new name reflects both continuity and evolution. “Bless” remains at the core, while the infinity symbol and the word “Forever” convey an ongoing commitment to create music together, even as the lineup evolves.
Fans can follow the transition and future releases via the band’s official page (Bless4’s X/Twitter account). While AKINO’s solo pursuits will likely continue—given her longstanding collaborations with industry veterans like Yōko Kanno—bless∞(Forever) is expected to keep providing theme songs for upcoming anime seasons, leveraging the siblings’ proven track record.
What This Means for Anime Music Lovers
AKINO’s departure marks the end of an era for a vocalist whose voice has become synonymous with several beloved series. However, the rebrand suggests that the group will still be a relevant source of anime and game music. Existing contracts for series such as Stitch! and The Ancient Magus’ Bride will be fulfilled under the new name, ensuring continuity for fans awaiting upcoming openings or insert songs.
For those tracking anime music trends, the move underscores how family‑run bands can adapt to changing line‑ups while maintaining a strong presence in the industry. As bless∞(Forever) embarks on its next chapter, the anime community will be watching closely to see which new series will benefit from the siblings’ signature blend of pop‑rock energy and heartfelt lyricism.
