U.F.O. - U Feel Overjoyed! -

"U.F.O. - U Feel Overjoyed! -" is a one-track digital single from 1 April 2023, and it stands apart from everything else in this catalogue. The song already existed. It had been written as a tie-in under sponsorship by Nissin's Yakisoba U.F.O. and released under the name of the singer Tokoyami Towa — composed by Shiren, with words by Fuki, which is to say by two members of Unlucky Morpheus. The band then recorded it themselves, and the description of their official music video calls the result a "Self Cover Ver." The "(Cover)" in the title on Spotify and Apple Music refers to that. The lyric opens on a promise to feed the listener honey sweeter than an angel's and turns on a repeated command to devour the moment. For a tie-in built around a product name, Fuki writes it in exactly the vocabulary she uses on the band's own records. The song stayed in the set for the fifteenth-anniversary tour in 2024 and is on the live album 15th Anniversary Tour 2024 REINCARNATION. It has never been put on a studio album; it remains a single of its own.
