Arcana Heart is famous for its exclusively female cast of combatants and its innovative ‘Elemental Alignment’ fighting system - that allows fighters to be paired with different elements for over 500 different character combinations.
Arcana Heart has developed a devout following of fans for its unique cast of characters, hyper-colourful artwork and fluid fights which take place as much in the air as they do on the ground.
So basically this seems like an anime styled fighter. I've not played the other games so can't comment on them, but £17.99 for a pre-order is pretty awesome.
If you're a fan of BlazBlu then this may be worth a look.
