Japanese deities are really fun to design. Perhaps because they are so overrepresented in popular culture, the artist actually has the liberty to explore more adventurous designs. For Amaterasu, I tried a more traditional Kanon-esque approach and a child, shrine maiden variation.
I ended up with the design that was inspired by the game Okami. The main character of the game is a wolf who receives power from Amaterasu to restore balance and peace upon the world. When running around, the wolf leaves a trail of flowers, symbolizing the life-giving power of the sun. I thought the idea of a life-giver was pretty neat and decided to try it out for the 3rd design. The end result looked great (and unique) so I went with it for the final.
More information about the character:
Role – Support
Skill 1 – Firestorm
Amaterasu casts a wall of fire in a selected area. Enemies standing on the fire will get damaged and burned. Allies standing on the fire will get healed.
Skill 2 – Passing the Torch
Amaterasu can channel this spell to a friendly ally. When this spell is channelled, the ally will receive an increase in HP regeneration rate. Amaterasu is immobile during the channeling.
Skill 3 – The Chosen One
If Amaterasu has more than half of her Mana pool remaining when she dies, she is instantly revived.
Ultimate Skill – Praise the Sun
Amaterasu directs the sun beams to a selected area. She teleports to that selected area, healing everyone (both ally and enemy) to full HP.
