When Ruki and Renamon are in great distress and are heavily losing a battle, something happens, like a symbolic holy thing
and Ruki unlocks Renamon's power to bio-merge. This is when, Ruki and Renamon both fuse together to form a being that exhibits
the bond between the tamer and digimon. Ruki's and Renamon's specific combination unleashes Sakuyamon.
I don't know why i did something like this, but I devoted a page to Ruki's awesome biomerge with Renamon to create Sakuyamon,
the Mega form of Renamon.
