I know, I honestly see this rp lasting. I have many things planned for the future for both my characters and everyone.
IE. the 'plan' to get the bells can be a plan when Ryuu and Mikasa fight briefly.
I also had a second battle in mind when they're older after Mikasa kills off her siblings it leads her, Ryuu and rukio to summon their contracted summoning animals or whatever.
I wanted Mikasa to be able to somehow retrieve a forbidden scroll that was written by Madara to summon the nine tails (similar to how Orichimaru summons manda and snakes, Mikasa summons foxes and possibly nine tails since i thought nine tails has no jinchuriki anymore)
Then in their second fight that in te end involves summoning we have nine tails the fox, Ryuu's wooden dragon, and Rikuos electric dragon. They use part of ther technique from the bell training on Mikasa, which is summoning the wooden dragon to push her back and use Amaterasu to burn some of the wood. Then Rikuo jumps in the air pretending to attach her and she uses fire balls in te sky to create cumulus clouds to have electric current. The heat of Amaterasu and close allows him to take lightning and summon the electric dragon from the sky. (he takes advantage of mikasa's fire/blaze release which is the heat.) Then Mikasa summons nine tails to their surprise and uses susanoo and of course in the end loses. Chakra all drained.
That's my idea so far, but I'm not sure if this will be approved moreover last!
