I must say i loved this manga, with only 5 chapters (atm) it already convinced me!
Characters 10/10:
"A super-smart-gentle-demon Prince & an innocent-sweet-pure-hearted-human Girl"
---and later some peoples join the story~:
"An easygoing-very-long wolf-clan-head Guy and uhm a super-justice-kinda-angel Girl"
Man, i hafto say that these characters are original,... well especially the super justice angel,
But about the main: Hana's looks are cute in its way, her hair is short, i, at first disliked that it was THAT short, but i gradually came to like it.. also i think the mangaka made her hair a bit more puffy, so yay~ Ahum, so the guy, Jirou, kinda a tsunedere, no? lol idk, but he's got such a big image in the demon world, he almost forgot to act normally in the human world, well in the end he did, automatically, cuz of the Hana~
