"Here, hold this." Anko gave him a small slip of paper.
"What is that supYEEEOWH!" The blond yelped, letting go of the small Raiton seal. Not a tag, since it just delivered a mild shock instead of frying the person alive.
Anko stared at his reddened palm.
"...well shit..." She drawled finally.
"The FUCK you did that for?" Naruto, still in his Nagi guise, rubbed his stinging palm.
"...Kid... You should have felt, at most, some tingling." Anko said slowly. "The chakra is molded to LOOK and FEEL like flesh, but it ISN'T." She rubbed her temples. "The seal sent a discharge of chakra, elemental but still chakra, in such a small amount it should have been dispersed by high density chakra covering your body easily, letting through maybe ten percent of the charge. Instead it... fuck, it acted like an actual, feeling, living body. Fuck, there is even a fucking FLUSH!" she pointed at Naruto's palm accusingly.
"Uh... is that... a problem?" Naruto asked nervously.
"Oh. No problem." Anko shook her head slowly. "There is no reason to worry at all. You just turned the fuck knows how many hundreds of years of the Shouken technique upside fucking down. Everything is A-okay."
"So... a problem." Naruto scowled. "But..." He halted. "Wait a minute. Your Kage Bunshin feel pain and even bleed and..."
"Kage Bunshin - Shouken is NOT a Kage Bunshin. Layering the Kage Bunshin chakra matrix over a body with it's own source of chakra is impossible." Anko said bluntly. "Why do you think henge is 'just' an illusion, huh? Why not make a version of Shouken that works with chakra being channeled? Because it can't be done. It's that simple. It is either henge, the illusion, or Shouken. And Shouken isn't ACTIVE enough to do something like this, while Henge is just an illusion. It would be like... fuck it would be like making henge actually physical! Just impossible!"
"...but I did."
Anko froze.
"...what did you say?" She looked at him, wide eyed.
"Uh... making henge 'physical'." Naruto elaborated.
"Run that by me again?"
"I made a jutsu... well made is too big, I just took a henge I tried to learn and... uh.. turned into a girl. Naked and stuff." Naruto rubbed the back of his head embarrassedly. Two years ago he didn't understand the implications. Now he did. But two years of exposure to 'Anko hotness' as she called her teasing, as well as noble women trying to seduce Saito Nagi and his Kokuen retainers all but crawling into his bed..."I called it Oiroke no jutsu."
"So?" Anko watched her partner like a hawk.
"After I... kinda shopped in it." He laughed sheepishly. "Not... naked. No. But... They were really polite to a sexy and friendly, girl than to the 'demon brat' you know?" He sighed. "Anyway, when I was... 'in' Oiroke I could... grab stuff. And I FELT stuff. One girl even slapped me for 'trying to pick up her boyfriend' and... she kinda left a mark. Like this one." He pointed at the reddened flesh.
Anko sighed, rubbing her temples.
"Breaking centuries of established seal knowledge... one jutsu at a time..." She muttered with a strangled chuckle.
"...Uh, that's bad?"
"Bad?" Anko sighed. "Naruto, you just informed me you made a fucking breakthrough that should be, according to any and ALL laws of sealing and what we know of chakra, impossible."
"Oh." Naruto frowned thoughtfully, before grinning. "Cool!"
