They swarmed, a flock, no, a legion of bats. Entering in among them, he emerged, a man so clouded in near mystic glory that they called him the shadow of the earth itself. Running outside had gotten to be far too slow of an ordeal and Endo had been forced to call out to those who protected him in all those battles long ago. He landed amid the battle in progress, managing to avoid most of the shots back and forth as the bats fell like a wave a darkness about him. Thanking them for their company and safe transport underneath his breath, he stood as they dispersed though he knew that they weren't ever far off from him at any moment. His eyes already having scanned and assessed the situation, he did the dumbest thing that he could have done in a situation like this, he sought peace instead of acting on pure shinobi trained instinct.
"Everybody stop!" he declared at the top of his lungs. If memory served him correctly, he had something akin to ten precious seconds before he'd have to pick a side and either way things went, he'd be betraying someone that he swore to protect. Pointing a finger with each hand, he motioned for all to stand back right as his voice began to fill the room again. "Sarunishi, you and your . . . friends get back. Ryujin Koyoko . . . you call off your clan right now! I shall have none of this fighting here of all places. I'm sure that this was all a big misunderstanding as Sarunishi is a highly honored guest and you of the Ryujin clan are an honorable family like few others." Time was no longer with him. Those precious ten seconds had passed and now was the time for action. He hadn't seen a person move yet but he could feel the calm before the storm. Chakra flooded his system, the sensation of every nerve being on high alert. One more time for the road? "Please, let's not do anything that we'll regret" Somehow, he really didn't think that much would change with his words, but if they didn't then he'd probably have a special cot reserved for him at the hospital.
OOC: Can't we all just get along?
