Bee as a pet however the item required to tame her is a reward for gaining a certain amount of points in the Arcade Mode. Be warn that it is extremely dangerous though. You can get a Gift (The non-bomb one from the toy factory) as a pet you should have a ribbon in your inventory that is used to tame it. and choose the one that suits your fighting style best.
The suggestion I have is to specify your pets: one for Health, one for Damage, etc. Be warned however that leveling up one aspect of your pet will cause the requirements of all aspects to increase, making it harder to level them up overall. They don't attack for you instead they provide a % boost to certain aspects of your character. They raise your pets level in certain areas such as Health or MP. Like you were doing before Kim, fish for more. You can check what cards you do have at the Menu > Trophy > Album. Very useful, and as you'll be grinding for materials anyway, you should get a few just as an aside. Each monster/creature that's not unique has a chance to drop a card that adds a passive boost to your character.
As that's too general an advise, here are a few more specific ones.
