Is this a serious question, at all?

Yes and no, I wasn't sure if there was any special way.

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. also after the mission can my character join your team if there's room since their both from the Rain Village?

Yes your character can be apart of my team along with Seranai and Nagi. His life will be a bit harder though, hope he's ready for it.
