Also to note is that Hibiki is so willing to do anything to win that she killed the Spirit Wolf that Goddess has given her and turned it into the bikini armor we saw in anime
I wish they had been more specific about that. It's so damned vague and isn't really explained well. When she said the armor was made from the pelt of a sacred beast I just assumed it was another beast on some sacred mountain and not the wolf. Hell I thought maybe the wolf left or died off screen to something else.
If you want tragic watch "YU-NO: A girl who chants love at the bound of this world" I've seen much worst anime but the tragic meter is around in the middle
In my opinion Navals dead was the only reason for all her hatred especially against demons, but later adapted to nearly any of the Demi-Human Races. She was (and probably will) never be able to properly process the loss of her idol, mentor and friend Naval. And what's even more tragic at this story - the real cause wasn't her, Naval herself, nor the demons who killed Naval, it was the fleeing "hero" weakling Tomoki. I hope she gets a clear mind again at some point in the story and faces off Tomoki, who treats women like trash and Lily even told him to do a body Transformation into a modified hyuman (with demon parts)... That's the perfect chance for her to make up for her friends death!
I would say Navarre was half human. Although not mentioned anywhere, she had a darker skin color, a red crystal on her forehead and reminded me of a Forest Ogre in character. So it's a shame we didn't learn more to show the heroine that she's doing wrong.
So far in the anime and have yet to see her chang to this extent. Wanting revenge on the 4 armed blue giant makes sense for her friend. And her killing and skinning the spirit wolf for armor was so damned vague. Would it be next season that we see a big change?
Spoiler Alert : She attempts to recruit Makoto into her "hero" party but Makoto refuses her because of her views on Demons and Demihumans. She then attempts to saduce Makoto but that also fails. Hibiki eventually gives up on trying to bring Makoto to her side and plots to get rid of him by sealing him away in another dimension sense he's so powerfull she can't fight him. That to also fails and Makoto ends up transcending human limitations and becoming something akin to a God if I recall correctly.
