"Like what you used against that ANBU!"

"Exactly!"

"How do I do it?"

"How good are you at controlling your emotions?"

"I'm not good at making them not-there, but I can keep calm and stuff."

"The key to the Hiryu Shoten Ha is the Soul of Ice, which is a technique that turns your battle aura cold instead of hot and involves temporary but absolute calm."

"What's a battle aura?"

"A battle aura is the natural emission of chi you give off when you're fighting someone."

"...What's chi? Is that like chakra?"

"Seems to be."

"Okay. And what's an emission?"

"...Uh, like, a lightbulb emits light and a stove emits warmth."

"Oh! Okay. How do I do the Soul of Ice? Is it just being super calm while fighting?"

"It's not just calm, it's--the next thing beyond calm. Like--this." And she breathes in, and out--

--and the temperature in her immediate vicinity drops a couple of degrees; her face betrays not the slightest hint of emotion.

"Cool. I don't know how easily I can do that, though." He concentrates, trying to go beyond calm, maybe if he meditates on it...

(He mostly just ends up with his face all scrunched up.)

"I'm not sure how to teach it, the way I learned kind of sucked."

"Hm... I might be able to try..." Yamato says, then concentrates. His expression goes blank enough to send shivers up Tetsuma's spine... And it does indeed get slightly colder around him. Not as much as it had around Ranko. "Of course, I wouldn't recommend the way I learned to do that either. Meditating on your emotions might be your best bet..."

"Okay. I meditate best after practicing though. There's no one around, so can I use my bloodline?"

"...Sure," Yamato says. "Just not too noticeably."

"Yay!" He turns to Ranko. "Wanna see something cool?"

"Sure!"

He closes his eyes and tunes in to the chakra of the plants around him. It's really calming, and his chakra patterns naturally sync to theirs. He claps his hands, slams them to the ground... And an oak sprouts under his hands, growing rapidly. He smiles slightly when it's done, then impulsively hugs it - it's just such a happy tree.

"Oh, wow!"

Grin. He then scampers up the tree and leans against the trunk and closes his eyes. Manning the tree had taken up enough chakra to take the edge off his restlessness, especially after running around all afternoon. He slips into meditating, and, well, he's certainly getting past calm, but he isn't achieving the cold calmness.

His chakra signature does become distinctly plant-like.

"...I think you're going in the wrong direction, you're getting soul of tree not soul of ice."

"I dunno how ice feels like though."
