You are Kusajishi Riku, Captain of the Seireitei's Ninth Division and the aunt of a certain pain-in-the-ass shinigami substitute. It's not exactly a clean-cut sort of relationship you have with the Shiba family, as you see Kūkaku, Kaoru, and Isshin as your siblings despite the fact that you're pretty sure Isshin and Kūkaku's sides of the family are cousins, but the Shibas have always played things a little fast and loose in that regard. To them you're family full stop, and with that complete acceptance comes certain responsibilities.
Chief among them, dealing with the fact that Ichigo and his friends seem to have this weird notion that you can solve any spirit-related problem they bring you. At the moment this means figuring out how to deal with “Senna”, a mod soul that's currently sought by the regai-Captains and their controller for reasons unknown.
“So what you're saying is she has a zanpakuto?” Ichigo concludes, excitedly. “Well, how do we get it out?”
“There's only one way I can figure,” you admit, recalling your own centuries of training and finding one constant. “She has to need it in a stressful situation.”
Senna glances at you nervously. “Why don't I like where this is going...”
“Because you have a good read on the situation,” Yoruichi replies cheerfully as your left hand's grip around the mouth of Tenkotsuki's scabbard tightens. “It's a rare skill these days.”
“Hey now, wait a minute!” Ichigo insists as it dawns on him what you meant. “That's not okay! Are you seriously gonna attack her when she can't defend herself?”
Senna's eyes dart away from you to rest on your nephew, then find their way back to you once more. “Not necessarily. I don't have to be the one to do it, though between you and me it won't be the first time I've trained a kid this way.”
“Hey, what do you mean 'kid', anyway!?” Senna retorts, nervousness temporarily forgotten.
