Umm they already introduced him in a previous chapter
He's like an archmage/master of the magic tower. From prev chaps, his personality is someone who loves researching, mostly abt Eugendiph's blood. Now, that Cecille had done smth extraordinary (to an egg/stone), he's also interested in experimenting things with her(like cutting her limb,etc) To be more precise, he's a mad scientist.(⌒▽⌒)
Oohh.. I can smell a love triangle brewing then.. I hope he falls for FL too so that the ML has a worthy opponent. Thanks for refreshing my memory!
Totally dunno who this guy is but he good looking and I like.. Any spoilers at this rate would be welcome (●'◡'●)
