I will preface this with the fact that there has apparently been some bad blood here, and I definitely wasn't the most friendly person on Discord, but I am seriously appaled by the behavior that you've been showing.
You do not have any right to ooRPly deny other people's characters' existence, family ties or anything. Not based on factions, not based on your own, not based on anything. The name Hideyoshi does not belong to you. You can claim that you're the true one, and that's fine. Other people claiming that however have just as much right to do that as you do. You trying to ooRPly force your way into influencing a Roleplay of which you have absolutely no way of knowing about inRP is absolutely disgusting and not worthy of somebody trying to become an official faction leader.
