Door

Door is the second ending theme for Denpa-teki na Kanojo (Electromagnetic Girlfriend), the 2009 OVA adaptation of the light novel series. Performed by Rumika, the song accompanies the closing sequence and serves as a brief musical coda to the mystery surrounding Juu Juuzawa and Ame Ochibana.

As a J-pop ending theme, Door emphasizes a clear melody and a restrained emotional tone rather than dramatic excess. Its reflective pacing suits the OVA’s themes of distrust, fragile alliance, and unresolved violence, allowing each episode to end on a quieter, more introspective note. The song’s understated mood helps soften the series’ tension while preserving the sense that the story’s central questions remain open.
