Is that an ogre? An ogre would fit with your lore but maybe it is a demon. Wait. An ogre is technically a demon, right?
I guess he is that one gate keeper who blocks your progress if you attack the stronghold to early. Girls definitely can use some leveling up in general anyway :/
I think ogre would be a good classification for him. Although Keisuma's name sounds Japanese, she is definitely not Asian. I am not revealing her actual name and ancestry until probably the end of the series. ;)
I see. I honestly mostly guessed because you use manga style and it reads like one, haha. I know that does not mean the setting has to be immediately Japanese but I guess that is the usual notion. It is true you used names like Odysseus as well.
Edit:
Also...I tried so hard for this prospective. And I realize that damn palace is too small!
