I.. don't think Howard is a girl?
Well it was stated in the site
Howard (Dwarf)
The eighth avatar. She has the hot-blooded and easygoing nature of her persona, and is neurotic and picky. An avatar created through the medium of Zaonic's pickaxe, 'Elinne'. She is learning dwarven techniques from Zaonic Steelstone in the workshop in the central area of Tirak. She creates the armored weapon, 'Titan'.
So I searched it up and found what the next avatars will be according to a wiki I found online
Avatars To Be Introduced:
Howard (Dwarf) she's female ya'll and will be the next one to appear (≧∀≦)
Hesperon (Wizard)
Hugo (Warrior)
Horus (Dragon)
Hela (devil)
Hun (ascetic)
Humpty (Artificial Spirit)
