So I have been thinking about this for a while. Isn't Heaven's Door literally invincible? We see in Rohans battle against the janken kid that he can cause people to commit actions with total success, seen when we reveals he wrote in the invisible baby "will save rohan if he is in danger" (or something along those lines), and it did exactly that. Also, he managed to write in Koichi or Okuyasu "cannot attack Rohan Kishibe", and it worked. So, couldn't he theoretically write in someone the few phrases "Is loyal to Rohan Kishibe", "is immortal" and "will always successfully protect Rohan Kishibe if he is in danger" and get an immortal loyal bodyguard that will never fail? He could literally beat everyone with this as long as he can stay alive, which can be done using another person with "is immortal" and "will always protect Rohan Kishibe from death". After all, it cannot fail, so even things like GER wouldn't be able to erase it, right?

I really want to know what others think about this.
