About the song
"Follow Me" is a song by Kagami Seira used in 2009 as the first opening theme of Isekai no Seikishi Monogatari, the anime also known as Tenchi Muyo! War on Geminar and 異世界の聖機師物語. It accompanies the AIC Spirits and BeSTACK production at the very front of the series.
As a J-Pop opening, it projects a bright, forward-moving feel. The melody stays clear and accessible, while the vocal line carries the song with a light but steady push from verse into a more open chorus. That shape gives the theme momentum without turning overly aggressive.
In the context of the series, that upbeat drive suits a story that moves from Kenshi Masaki’s abrupt arrival in Geminar into school life, rivalries, and mecha conflict. The song introduces the world with energy rather than tension, setting an adventurous tone for a fantasy narrative built on motion and dislocation.
