Lagoon Engine Einsatz(ラグーンエンジン アインザッツRagūn Enjin Ainzattsu, romanized as Lagūnenjin Einsatz in Japan) is a Japanese manga series written and illustrated by Yukiru Sugisaki that has appeared in Newtype USA since October 2004. In July 2005 an announcement was made that ADV Manga would be distributing the series as graphic novels starting November that year, one volume has been released so far. It has been suggested that this series is related in some way to the manga series Lagoon Engine by the same author, but no official statement has been made by the author or publishers to support this idea.
