Seraphim Call is a Japanese anime series by Sunrise from 1999. Seraphim Call may be considered avant-garde in several respects. For example: it is an anthology of individual stories while most other anime is serialized. Other examples include a surprise ending that comes at the beginning of one of the stories, an episode seen entirely through the eyes of a plush toy, one is largely a Thunderbirds parody, and two nearly identical episodes from individual twin perspectives. The experimentation in plot structure can be very subtle often requiring the viewer to watch each episode twice before noticing it.

Bandai Namco Filmworks Inc. , previously and still famously known as Sunrise Inc., is a Japanese company owned by Bandai Namco Holdings with its business focused on production, planning and management for anime.
