Uhm i think the one who destroyed the mansion was not the human but this blonde girl

She was there before joining the fight.
I think you read my comment wrong, as i only mentioned the mansion being destroyed. I never said it was a human who did it, i am quite aware of the fact that it was destroyed by the traitor clan leader with the two swords.
The 3 facts mentioned are reasons for Frankenstein to be mad...
haha sorry for getting it wrong, 'cause when u said PEOPLE i thought u mean the human who were also trying to attack Lukedonia. (⌒▽⌒)
Haha
Ill explain the comment before you get confused again.
The first part "PEOPLE" literary means Humans, Nobles, Werewolves :3 Anyone/Everyone who goes against his master. It has nothing to do with the 3 facts i mentioned, those are just events that happen that made Frankenstein pissed off.
Actually this was quite clear to everyone else who read your comment
People should learn not to mess with the master. Frankenstein is an extremely pissed off mood.
First: They destroyed his masters plane while he was inside
Second: They decided to shoot him with guns
Third: They destroyed his masters mansion.
If they do something else to mess with his masters, such as attacking him out of nowhere or badmouthing him. He is probably going all berserk on them. Ah his love for his master is just too adorable :3
