"A bit of a kindred spirit, I see."

"Tobirama doesn't bring me out to talk to new people nearly enough."

He chuckles a little, at that. "Is it costly to let you stay here? Maybe I can bring you with me in my travels, sometime."

"It is not, though I do enjoy helping Tobirama."

Nod. "Well, if I find something I think you'd like. It doesn't have to be a long trip; I can teleport to places I've seen, and bring a few passengers."

"That makes sense, especially if it's somewhere my or Tobirama's presence wouldn't be considered hostile - I'm effectively a retainer of his."

"I should stick to places like that anyway, I think, until I've figured out how to explain myself in a way that makes more sense to people here. Do you have an idea of what you'd like to see?"

"The northern continent - we used to have a summoner from there but not since before I was old enough to be summoned - and big towns with odd people."

"I can do that, I bet."

"Thank you."

"Would you like to come with us? We're going to be checking to see how my healing magic does with chakra-related problems."

"Sure; that'll be interesting." They stretch, and go to briefly lean against Tobirama's legs.

Cute!

Onward?

Onward.

The hospital is close, at least, and Tobirama handles introducing Raafi to the staff and the monitoring procedures and the relevant tests they'd like to perform now. (The medics would prefer to be actively monitoring someone with chakra during a healing attempt, but are unsure if that would interact strangely.)

"I don't expect it to interact dangerously, if it interacts at all; there's not much that can go wrong with positive energy. We can start with something simple, though, to check - the basic healing, I think."

The medics think that seems sensible, yes - and they have a minimally complicated case lined up for that initial test. Simple injury, no chakra exhaustion.

He chants; his hand glows blue, and he touches it to the patient.

The patient: is healed!

"Fascinating," says the attending medic. "That's nothing like our own medical ninjutsu."

"I'd suspected that. Does it seem likely that it'll be useful, or do you have its effect covered already?"

"We have its effect covered, though you might have an easier time with some complicated wounds than we do."

"And I can heal more than one person at a time, if there's ever call for that," he nods. Then, to Tobirama: "Did you have something in mind to try next?"

"If the same spell works on chakra exhaustion, since you said that chakra exhaustion sounds like non-lethal damage under your system."

He nods. "Do you have someone available to try it on?"

The medic pipes up with: "Yes. Chakra exhaustion's fairly common, though usually only in the minor stages, and hard to treat with anything except rest."

"All right. I can do two more like that tonight without cutting into the other tests we'd like to do."
