SEKAI NO OWARI will release their new single "Stella" on July 8.

"Stella" will be released through the band's newly established company S.U.N.S, along with Universal Music's new label Capitol Records. Composed by Nakajin and written by Fukase, it will mark the first release of their 15th anniversary year.

The CD will be available in three editions: a regular edition, a fan club-exclusive limited "Phoenix" edition, and a limited anime jacket edition. The "Phoenix" edition will include Blu-ray and DVD footage from the group's 'SEKAI NO OWARI ASIA TOUR 2025 “Phoenix” in TOKYO' at NHK Hall.

Artwork for the regular edition was illustrated by Bokyaku Zukan, while the "Phoenix" edition features artwork by Shohei Takasaki, who also performed live painting during the band's Tokyo show. Details on the anime jacket edition will be revealed later.
