Eien （永遠）

"Eien （永遠）" is performed by Yuusaku Kiyama and appeared in 2008 as the first ending theme of Skip Beat! (スキップ・ビート！). Used as ED 1 for the television anime, the song belongs to the 2008 adaptation produced by HAL Film Maker. Its placement at the end of each episode gives it a clear closing role within the series.

Musically, "Eien （永遠）" is framed as J-Pop, with a polished mid-tempo approach that favors a clean melodic line over a dense arrangement. The vocal delivery stays direct and steady, while the refrain opens wider than the verses and gives the ending sequence a softer emotional release. The result feels controlled rather than dramatic.

Within Skip Beat!, that calmer tone works as a counterweight to a story driven by humiliation, ambition, and performance. Where the series often pushes Kyouko Mogami into competitive and emotionally exposed situations, the ending theme steps back and closes episodes on a more reflective note. As an ED 1 from 2008, it is tied directly to the anime's original television run.
