Arc the Lad (1999) : 1x1

A mysterious air ship hijacking triggers a distress call to which bounty hunters Elk and Cougar respond with explicit instructions to rescue the passengers and capture all hijackers. Aboard, they realize that there's only one highjacker, and his motives are baffling at best. Soon, Elk and his team find themselves unwittingly at the center of an elaborate conspiracy that involves a young girl, Lieza (who has the ability to control monsters), her lion-like pet, Pandit, and a government agency engaged in human experimentation.
