How would the Sakamaki’s feel about Ritcher attempting to steal their s/o seeing how she’s very kind and sweet to him despite not knowing who he truly is and he misinterpreted it as her being in love with him

Admin Mawile: (o゜◇゜)ノ Uh oh…

Shuu:

-He’s not usually one to bother too much with little problems, but something about his uncle infringing on what’s his is a good way to get him to get territorial. Richter has no place making a move on what’s not his.

Reiji:

-He’ll try to handle the situation respectfully, at first, but if that fails, well, it may be as good a chance as any to get someone troublesome out of the picture. While Reiji has respect for his father, Richter is a different matter. 

Ayato:

-After everything Richter has done, this is absolutely the last straw. He’ll at least try to off his uncle, and if that fails, he’ll take things out on you for “tempting him” in the first place, even while you’re owned. 

Kanato:

-Aside from whatever violent things he tries with Richter, he spends a lot of time blaming you for attracting the attention of another man. You’re likely to be hurt as well, all as part of Kanato’s typical jealous rage. 

Laito:

-Considering his history with Richter, this might end in one dead vampire uncle. Laito has had more than enough of Richter getting in the way when it comes to people he “loves” and is likely to react very violently to the situation. 

Subaru:

-He’ll get straight to the point… of making a good attempt to murder his uncle. Subaru is quick tempered and quick to violence, and among vampires, it’s not at all uncommon for territorial disputes to end in blood.
