Ninjas vs Nue
Yaya handled the guards outside and is now sleeping.
The Ninja's got fucked up by that girl but were able to apply a teleport talisman to her bare skin via deception.
Yuuna probably has her own problems.
Well, Yuuna's been semi captured by Karura. Yaya took out some guards that discovered them, but exhausted herself and is now taking a cat nap. Sagiri and Hibari teleported Mitora away to the northern most point in Japan, but Sagiri seems to have exhausted herself in the process and is now being helped around by Hibari who probably burned a fair bit of energy herself.
So unless Nonko and Oboro wake up and get there quickly, it's pretty much up to Yuuna to single handedly beat Karura or free Kogarashi. That's not exactly smooth sailing.
Teleporting Mitora to the northern end of Japan basically exhausted Sagiri. Mitora can probably be back in a few hours at basically fully strength, and Sagiri will likely need a good night's rest to fully recover. That's not really a long term solution.
Sure it probably takes less energy to teleport a shorter distance, but then the target has less distance to cover to return. It's probably a technique more intended for escape. Teleporting yourself a few miles, or even a few hundred yards away from a fight you're losing would be a great way to avoid capture or live to fight another day.
The bare skin likely isn't a requirement. It was just needed for Mitora so that she didn't just remove whatever article of clothing it was placed on before the jutsu could activate.
