[Machine Translation] The new single will be their first in 5 years and 3 months since the release of "Snow White Girl" in December 2019. 2025 will see the group re-launch as a 5-piece with 3 original members, Kowta2, who has supported the group for many years as a support DJ, and a new member, KAI, on vocals. The title track "Happy Ender" is the first song of the new five-piece group. The title track "Happy Ender" was written and composed by member U, and is a song about the determination of the five members to move forward on the path they have chosen for themselves, and is a song of support for those who are starting anew in a new environment. The coupling song, "She," is a song about a lost love written and composed by a new member, KAI. It is a song that gives a great impression of KAI's potential for the future.
