@Lunathe_Wolf135 first of all, thank you for reading my book, it means a lot to me <3
Second of all, I wouldn't say I'm the best with words so apologies if my description comes off as a bit hard to understand or perhaps even a little inaccurate to the canon character
Malleus, like you said, is a complex and beautiful character. He's a calm but lonely person that just wants a friend that he can speak to without being feared for his magic or reputation (hence why he appreciates the mc's friendship). I'd even say he has a hidden mischievous side that shows he has a sense of humour cuz it's been shown that he likes messing with people sometimes (though house jokes are often misunderstood). Unlike other nrc students, he can show kindness without wanting anything in return and he's really attached to his family (Lilia, silver, sebek). He appreciates gargoyles and abandoned places because of their long age and gargoyles for protecting the area (? I forgot (╥﹏╥)) despite this all he still has to keep up a regal composure, because he is the next in line for the throne in briar valley
This is what I make of him! It might be wrong so I recommend doing more research just in case </3 but I hope it helped somehow! :D
