Jutsu Used:
Wisp
E-Ranked Ninjutsu
After performing the needed seals, Kotaru creates up to five, wispy teardrop shaped balls of flames five inches in diameters. The flames produce no heat and are incapable of inflicting burns. The balls float within three feet of his position and up to a foot above his height and cannot move outside of this area. The fireballs move with him but are otherwise immobile and once created Kotaru cannot control their movement or position. Due to the low chakra cost of this technique, Kotaru can maintain this for x number of posts where x equals stamina/2.
~Basic Formation: Eroshiin
D-Ranked Ninjutsu
Channeling chakra to their shiin, they cause it to inflate, fully forming into its full glory. Taking the form of wings, they are incapable of flight on their own, however are very aerodynamic, allowing for the user to slowly float down, based on their prerequisite taijutsu. The Eroshiin has a strength equal to 3/4ths the user's strength.
As he neared the bottom he slowed his descent significantly and eventually landed near soundlessly on solid ground. He looked up, waiting for Kazuo and Koji to catch it. It seemed he had slightly outpaced them and had landed first. With a crack he lit a flare and held it above his head. They had landed in a huge open space, and the jounin's flare illuminated what lie silently around them. Towering bones rested on either side of him, rib cages large enough for half a dozen men to stand inside, one on top of the other. He stared without speaking, waiting for the others to join them.
The trio had a long way to travel before they reached the spirit colony. It had been some time since he had visited, but the way there had been essentially seared in Kotaru's brain. The Catacombs was his least favorite place in Iwagakure, but it was a place that needed a considerable amount of attention. It was still new to them, and as far as he knew they had barely begun to explore it. Any deviation from the path could lead to unexpected and potentially disastrous encounters with angry spirits or giant creatures influenced by their chakra, and Kotaru wasn't exactly in the mood for a fight.
When they joined him he'd announce, "The Black Garden. Final resting place of gigantic fucking rats. Better not linger." He could practically feel the creatures somewhere behind the veil of darkness, and the knowledge that they were most likely skittering just beyond the light of his flames and flares made him agitated. His fingers flexed and he started to move forward again urging his companions to keep up and stay close.
A-Ranked Discipline Taijutsu
Type: Eroshiin
Requirements: ~Glide
Stretching their shiin to their fullest, the Akari is able to fly just as well as any bird would be able to, up to a maximum of 30 meters. Other than the height restriction, the user is able to travel equal to their speed, treating it just as if they were moving on land.
Quiet on the Landing
C-Ranked Taijutsu Discipline
Kotaru has mastered landing quietly after jumping or leaping from a great height and is able to do so without injuring himself. Only those using specialized hearing techniques are able to hear his nearly completely silent landing.
