I hope there is a difference later on if MC is cold-blooded or Pacifist/non-lethal. cold-blooded high rank MC looks unto the eyes of his enemies with such intensity that the enemies are suddenly preoccupied with the flashing of their lives as death creeps up on them. Non-lethal high rank MC beats up enemies even with guns (like Batman) or expertly and accurately targets non-vital parts of enemies that can still disable them during a fight (shooting the arms to disable them or probably permanently paralyze them), having the patience to deal with his enemies earns him the respect of other family member and the silent respect and fear from other families.
I hope we get to choose the weird quirks or not of MC later on once he is high ranking, some examples:
1. Trips everywhere in normal situations but gracefully moves likes a shadow once serious or bloodthirsty.
2. Wears ridiculous outfits (I hope we can dress up MC later on) like this:
3. His grumpyness reaches a reaches a high level.
4. Licks Luna's melted ice cream on the floor. Which in turn weirds out and turns on Luna......and Wilfred.
