> That's fine, we can let them out to resolve future incidents as needed. The important thing is that we've hoarded them. They're ours now. All ours...
> If Mima is inside the shrine, make her a part of our tail.
> With what little moving we're still able to do, uproot more trees and add them into our body. Make sure that, once we get to a point where we can't move around anymore, we're located and positioned in such a way that the shrine is where it's supposed to be.
> Then, using the extra mass from whatever trees we were able to get to before we settled down in place, change our shape so as to extend some body mass outward, forming it into a body that looks exactly like ours from when we became a main character. Control this body (which is presumably still physically connected to us) and have it move around the grounds, uprooting and absorbing more trees. Keep continuously spreading out all around the shrine grounds and beyond, uprooting and absorbing trees as we go, in the background of all other actions.
> When we get enough extra mass to spare, reshape ourselves by shooting some of our mass up through the gaps in the floorboards of the shrine and form two more bodies inside, ones that looks exactly like ours from when we became a main character. Have these bodies get in bed with Reimu and snuggle up next to her, hugging her from each side. All ours...
