i had fun getting to know of Darian briefly through this spin-off prelude, including that headbutting moment haha mc certainly got the spirit against him. best end would be the third end/neither love nor hate, it gave a sorta mysterious-intriguing vibe or hook in this distance with him since mc is still not that close to him. im also a bit interested in the golden knight painted in this heavenly light or aura to him, would be funny if he turned out to be angelic being arch-nemesis of Darian then it would be a love-triangle. thats just my theory imagining thoughh.
So heres angy Darian and his first look, i loved long, baggy sleeves that drape over the hands.

And the final look after he got his precious horns and wings back, with his happy approval, a correct choice for him to trust my judgement <( ̄︶ ̄)>

all in all, you got a glimpse of the cute, charming and naughty Darian, looking forward to the full release of his story!
