Kashi Mikei's Jutsu List(WIP)

Name:Fire Style: Combustion Ash Cloud Jutsu
Kanji 火遁・灰積焼
Rōmaji Katon: Haisekishō
Data
Classification:Ninjutsu
Type:Fire Release
Rank:B-rank
Class:Offensive
Range:Mid-range
Hand seals:Snake → Rat → Snake → Tiger

The user spews a stream of Chakra-altered gun-powdered ash from its mouth, which surrounds the region. The gunpowder itself is hot enough to cause third-degree burns on the victim, and because it's composed entirely of ash, it stays in the air around the victim like a cloud. For further damaging the enemy, the user can ignite the ash with a flint placed on their teeth beforehand to create a spark, resulting in a violent explosion. However, this technique requires keen senses to read the air currents, the insight to read the movements of the enemy, the tactical experience to not also enfold one's allies in the flames, and careful attention for the timing of the ignition.

Name:Fire Release: Flame Bullet
Kanji:火遁・炎弾
Rōmaji:Katon:Endan
Data
Classification:Ninjutsu
Type:Fire Release
Rank:C-rank
Class:Offensive
Range:Short to Mid range

The Fire Release: Flame Bullet technique is executed by the user gathering oil in their mouth which is created by chakra, spits it out, and ignites it. This technique simply shoots a flame bullet at the enemy. If the amount of oil that is prepared is kept down, the time it takes to invoke the technique is reduced. This allows the enemy to be stricken unaware, allowing the oil-containing flame bullet to burn them up completely. It is also possible to shoot out a series of of flame bullets by partitioning the oil. If this technique is fired after covering the enemy with oil using the Toad Oil Bullet, it has plenty of power to wound or kill. As this also keeps down the consumption of chakra.

Name:Fire Release: Big Flame Bullet
Kanji:火遁・大炎弾
Rōmaji:Katon: Dai Endan
Literal English:Fire Release: Big Flame Bullet

Data
Classification:Ninjutsu, Senjutsu
Type:Fire Release
Rank:B-rank
Class:Offensive
Range:Short to Mid range
Fire Release: Flame Bullet

This technique is a senjutsu altered version of the Fire Release: Flame Bullet. The user fills their mouth cavity with oil, created inside the body with senjutsu chakra. This oil is then spit out and at the same time ignited, which creates a giant flame, equivalent to ten-odd Flame Bullets. This flame can completely cut off the front escape route of an enemy cornered in a hallway or room, or it can thoroughly burn each respective escape route.

Your hydration tech isnt going to fly at this rank. Maybe when you are sp jounin or jounin. I glanced over the rest and it seemed ok..so I will approve this jutsu list after you remove the "Hydration tech"
