Could someone describe the Jinchūriki process to me? How the extra chakra is accessed and all that jazz?

you simply ether have to beg your tailed beast to give you his chakra or you excess it in times of deep emotional rages kind of like the super saiyan transformation. i think there also is a way of unlocking the ability to draw from your tailed beast's chakra without their consent but that would require a lot advanced control and messing around with the seal that keeps the beast inside the Jinchūriki. there also is breaking the seal which releases the tailed beast and they will transform in to it, but it will kill the Jinchūriki, and then there's developing a close relationship with them, but for the sake of not power playing, if your character hasn't developed one yet then try to have disagreements with it and take time to bond with it because that's kind of how it is in the show, it also makes it more interesting. also after the mission can my character join your team if there's room since their both from the Rain Village?
