so you're an amnesiac ex-yakuza who makes friends with this kid and his pet cat type thing and somehow you take over this kinda age of discovery-looking pirate ship but like it has afterburners and then you get involved in a nuclear waste cleanup off the coast of Hawaii where you sail around summoning mythical beasts to beat up buccaneer bad guys but you can also chill out and do a bit of fishing with a grappling hook or play arcade games but also make sure you don't forget to occasionally feed the cow.
