ウルトラマンZ オリジナルサウンドトラック

Yaoi, often called Boys’ Love (BL), is a Japanese-originated label for music connected to male–male romance properties in manga, anime, drama CDs, stage musicals, and games. In music contexts it most commonly refers to character songs, opening/ending themes, image albums, and drama-CD soundtracks performed by seiyuu (voice actors) and J‑pop/J‑rock artists tied to BL series. Stylistically, yaoi/BL music draws on mainstream J‑pop and J‑rock aesthetics: bright pop hooks, emotive ballads, sleek electronic production, and band-oriented pop rock. Vocals emphasize expressive delivery—often by the same voice actors who portray the characters—so lyrics highlight longing, devotion, bittersweet nostalgia, and romantic catharsis. Releases frequently include duets and call‑and‑response parts that mirror narrative relationships, and many tracks appear in both “TV size” (OP/ED) and full-length versions.
