The poison, which was successfully tested on the Kumovians a few years ago, has been tweaked for the purpose of capturing such personalities, and now it works even faster and even Kage will be unhappy if he inhales just a little bit of it.
Of course, it has a weak effect on me, but I doubt Rasa has as good a resistance. Or there's another volatile poison that's odorless and colorless - it's not deadly in itself, like the last one, but the best part is the imperceptible loss of the ability to control chakra.
The more of it ingested, the more significant the effect, but it only manifests after the victim consciously tries to use the chakra to apply ninjutsu or strengthen the body. It's pretty sneaky, but unfortunately it's difficult to produce and only effective in a small room due to the small amount of the substance.
You can't use it in outdoor combat. Yes, it can be used against ninjutsu practitioners or kekkei genkai of the energy type, but hand-to-hand combatants or kenjutsu users will suffer from the poison only to a limited extent, due to their more developed physical data.
The more chakra a poisoned ninja has, the more effective the poison is, but at the same time, the natural current in the keirakukei is not disturbed and passive properties are preserved. Moreover, the effect is cumulative - the more one inhales, the stronger and longer the result will be.
Even with my resistance to various poisonous substances, a five-minute exposure reduced my chakra control to the most basic level, when I couldn't use anything more complex than D-rang for fifteen hours, and the losses were monstrous by my standards.
In the two years since its development, I've only received six doses of the poison, due to the rarity of the ingredients needed to produce it, but two of those were spent in testing. Given the importance of capturing Rasa to my plans, I had prepared two doses of Killer S-ranks to minimize the risks as much as possible, several sets of Fuin and last chance scrolls as a safety net. All that remained was to wait.
The tugging sensation of summoning didn't come until two days later, late at night, when I was already preparing to end the day.
A reinforced clone was sent to the bedroom, and I rushed to the closet with the uniforms, picked up the pre-assembled pouches with everything I needed, fixed them on my belt and hip with a couple of movements, then took Samehada in my hands and stopped resisting the growing tension.
Poof.
In the next moment, my surroundings changed from a well-lit basement, very cozily arranged, to a very sparse forest, at the moment, wrapped in darkness, which was dispersed only by the occasional moon peeking through the clouds.
A few kilometers away from me, I could feel many of the faint sources of the ordinary people who lived in the town, and among them the muted but still perfectly identifiable chakra of the former Fourth Kazekage, who had set a world record for the shortest reign.
Touching the dark figure standing next to me, I exchanged chakra to get an idea of the current situation - Rasa had purchased a small house on the outskirts of the city and spent most of his time inside, under the cover of a barrier designed to hide its contents from sensors. Weak clones, almost indistinguishable in strength from ordinary people, went to the market for food.
Except that the barrier he used was not of Uzumaki's manufacture and had a small flaw that made it possible to detect the shinobi if one was familiar with his chakra source signature.
Unfortunately for Rasa, even if I didn't have a good memory, he was constantly monitored by a shadow clone that had scouted out both the house and the target's daily routine, allowing him to plan the moment of attack without even appearing nearby, and the barrier had no additional functions like intruder detection.
The former Kazekage usually went to bed at eleven o'clock - about that time - every day, so I had to wait a little while for him to fall asleep before I could act. In the meantime... Tiny vials of poison went to one shadow clone, four metal disks densely scribbled with hieroglyphics and symbols, along with a last chance scroll to another who had left his observation post at the moment of my summoning.
