There niti: a bubble Mage: he's more of a support class
Yuuka: also a support class but we have yet to see her go on the offensive.
Hana: the strongest Mage in lamia scale. She is purely offensive from what I see.
Kei and mei: nukodukes that are at lamia scale.
Sage: Mage that doesn't use his magic nor his voice: because he has no vocal chords.

Then there is you:)
