Water Angel

Combat
An Aquatic front-line support unit with good Health, solid stats, and a good range of skills.

Water Angels are quite robust for support units, allowing them to enter the fray to help their allies. That they can equip both weapons and armor as well, when many other support units can't, means they need not shy away from combat.

You could even make an Endurance Level Type for tanking purposes. While their Health stats fall short of the more easily obtained Fish Taur, they are that much more resistant to Lust Damage with higher Lust Resistance and Max Lust, as well as lacking Bad Anatomy.
