Oriko isn't really about to shoot without some confirmation that the two are attempting to attack, but he accepts Yuudai's order not to fire without him checking up on them first. Better him than Oriko, honestly, since the medical ninja had little melee combat experience, and he'd only picked up the injection shot sniper recently when he'd been given the option of using weapons as a ninja. He's a bit surprised at Yuudai's sudden movements, but he follows the orders of the other shinobi, looking through the scope of his sniper shot to see the interaction, allowing him an up-close view despite being dozens of meters away.
Therefore, he can see almost as well as Yuudai does as the Chuunin approaches, that the two shadowy men are actually small cloaked lanterns, covered with enough drab gray clothing that they could not float upwards as they normally do when released for festivals, but instead float at a height consistent with people, making them clearly distractions upon much closer inspection. Immediately, Oriko turns his head to look in the opposite direction, seeing another group of people approaching, though these people are moving much more swiftly, and there's an actual flash of knives as they move in. Oriko scoffs, and immediately loads one of the shots of poison into his sniper shot, aiming at the nearest and slamming his palm into the back of the tube, causing the shot to sail, having used his training in basic weaponry to aim his shot in the target's path, rather than where he was when the shot was made.
It had taken some knee-jerk mental calculation, but Oriko was good at that; the man he'd hit fell to the ground a few moments later, his blade launched away by his tripping as he holds himself while his body is wracked with pain at every little touch; with the rain seemingly assaulting him, it rather immediately overwhelms him, leaving him clawing at the ground as he screams out.
Oriko ignores him, and instead starts focusing on the other approaching vagabonds; he counts three others, and that's likely too many for just his injection shots to take down. But perhaps... He slings the sniper shot over his shoulder and waits until the next one is at least a lot closer, at least within hearing distance, and just as he approaches the little medic with the clear intention of taking him down so the others can do their work on the parade float, he makes the same kind of noise that he'd heard the Academy instructor make when he's about to start chastising a student, while he forms a hand seal to mold his chakra.
"Tch tch tch."The bandit would react as though the blue-haired boy had disappeared, and Oriko would use this opportunity to move away from the bandit that had tried to take him out, causing the bandit to spin about, reacting with horror at seemingly nothing, though he'd be under Oriko's illusion that the blue-haired Genin had managed to sneak through the rain and attack him from behind, leaving him open to an actual counterattack while Oriko himself slips away from the melee.
NAME: Ame no naka no Toppū [Gust of Wind in the Rain]
RANK: C
CHAKRA USAGE: Low
CLASSIFICATION: Genjutsu [Visual]
HANDSEALS: 1
TRIGGER: Auditory
REQUIREMENT: Amegakure no Jutsu [Hiding in Rain Technique] x
DESCRIPTION:
This technique demands active rainfall in order to operate, be it natural or manifested via a separate jutsu. Following the sound of three quick 'tch' sounds, like a disappointed teacher clicking their tongue against their teeth, the user of the genjutsu will seemingly disappear from the target's view, as though they had used the Hiding in Rain Technique. Within a short moment, they will suddenly reappear next to the target, emerging out of the rain to attack them. This technique can be employed while one is already using the Hiding in Rain Technique, though admittedly to less dramatic effect.
If they so choose, the user of the technique can refrain from disappearing at the start and, in turn, alter the appearance of the form that emerges from the rain. While the subject of the user's projection doesn't have to be someone intimately familiar to either party, the less familiar the user is with the subject, the easier it is to identify the fake. For this reason, users often elect to pattern their illusion after a comrade or a well-known figure, if they choose to alter the illusion at all.
