nah I agree, but I also just really want to get this rp off the ground while my muse is fresh
My character's mother is a sealmaster, perhaps she could have been present at the jinchuriki's sealing and even helped with the seal? For whichever team he's assigned.
(Also I'd like to note that I, personally, know jack and shit about how fuinjutsu works so I'm gonna wing my character's knowledhe to the best of my ability. P: )
