The cutscenes were anime-styled, there were two protagonists: a swordsman helped by the power of darkness (a black cat called Nero) and a gunslinger helped by the power of light (a sunflower). There was a bank clerk that told you that if you had Boktai or Boktai 2 in the GBA slot, you recieved a special bonus. There was 6 or 7 element spirits like the cat and the sunflower: darkness (Nero), light (sunflower), ice, fire, wind, and a green one which I think was earth. Each "dungeon" had a certain climate that affected the spirits power and the usability of items in your inventory. And one of the bad guys was a vampire. That's all I can recall. Ring any bells with anyone?
