Choku's Jutsu Registration

Name: Gentle Rain Style: Swift Tide Pierce
Rank: A
Chakra Cost: 70
Force: Strength+Speed/2
Type: Bukijutsu
Element: N/A
Hand Signs: N/A
Range: Short Range/0-2 meters
Requirements: Have Byakugan active, be taught by Choku or someone who knows the technique
Description: The user, enhancing their vision with the Byakugan, allowing them to see the opponent's tenketsu, strikes swiftly with either the hilt/handle of their weapon or the tip of their weapon's blade at 3 tenketsu points around each of the target's shoulders, one strike projecting chakra outwards to hit each of 3 points per shoulder. Projecting their chakra through their weapon, the user effectively eliminates the use of the target's arms for one post through the disruption of their nerves and chakra flow. A target whose Endurance is higher than the force of this attack may counter this and still use their arms, but no jutsu involving the flow/molding of chakra can be performed for one post.
Drawbacks: Is a close range technique and requires physical contact with the target.
Combination with other techs: N/A

Name: Rain Man Style: Tsunami
Rank: S
Chakra Cost: 150
Force: Chakra*2
Type: Bukijutsu
Element: Water
Hand Signs: None
Range: When projected, the attack goes 20 meters before dissipating
Requirements: Be taught by Choku or other who knows this technique
Description: The user imbues their weapon with powerful water chakra and either slashes or jabs at the target. The water chakra is released from the blade and manifests as a large, powerful wave of water, with a height of 20 feet and width of 10 feet. If used at close range, this technique can be fatal, and if the wave makes contact with physical mass, highly destructive.
Drawbacks: An Earth barrier created by a user with Chakra equal to this technique's force can completely block it, and a Wind technique of equivalent force can disperse the technique altogether.
Combination with other techs: Can combo with other Water Release techniques

1st Technique: Determine if you want 1 strike for 3 tenketsu points or 3 strikes for 3 tenketsu points. Add that you must have chakra conductive blade

2nd Technique: The wave or the blade can cut? If the wave, that won't make much sense. A wave that big would have concussive force, not cutting. If the wave was thin than I can understand it cutting.

Edited

Approved.

Name: Rain Man Sealing Method: Bloody Bullets
Rank: B
Chakra Cost: 45
Force: N/A
Type: Fuuinjutsu
Element: Blood Release
Hand Signs: Half Tiger Seal
Range: Blood can be manipulated out to 10 meters from the seal's location
Requirements: Be taught by Choku or other who knows this technique, have access to Blood Release (Taught or part of Shoshinku, no other elements than Water)
Description: The user places a seal on a surface, most commonly on that of a weapon, and draws their own blood through blood manipulation and pours it into the seal. At any time, by forming a half tiger seal and saying "Release", the user can release the seal and project the blood at high speed towards a target through blood manipulation. This can also be used to seal other people's blood, like all Blood Release techniques.
Drawbacks: The common drawback of all Blood Release techniques, if the user uses their own blood for these techniques 3+ times in a thread, their Endurance is cut by 25% for the remainder of the thread
Combination with other techs: Can be used in conjunction or as a medium for all other Blood Release techniques, including the ability to prepare Blood Release techniques and seal them using this technique.

Name: Hiding in Mist Technique
Rank: D
Chakra Cost: 15 (If doubled the thickness of the mist increases, making it nigh impossible to see without Byakugan)
Force: N/A
Type: Ninjutsu
Element: Water
Hand Signs: Tiger
Range: 30 meters
Requirements: N/A
Description: The Hiding in Mist Technique is a speciality of the ninja from Kirigakure, where one causes a mist to spring forth by lifting up some water from either a pre-existing source or expelled from their mouth, then goes in and out of sight at will from within the pearly-white realm. The mist's thickness is controlled by the amount of chakra kneaded into it. It can't fool the Byakugan, but, due to the mist being created with the user's chakra, any Sharingan and Rinnegan-user will see the mist coloured by their opponent's chakra, which will effectively hide the user from the dōjutsu.
Drawbacks: N/A
Combination with other techs: The mist from this technique can be used by Choku's ability, "A Man at Peace With Rain", or other techniques that utilize mist.

Name: Water Prison Technique
Rank: C
Chakra Cost: 35
Force: N/A
Type: Ninjutsu
Element: Water
Hand Signs: Snake → Ram → Horse → Hare → Ram → Horse → Hare → Hands spread in front palms out or Snake → Ox → Clap Hands
Range: Prison can be formed up to 2m away from user
Requirements: N/A
Description: This technique is used to trap a victim inside a virtually inescapable sphere of water. The only downside to this technique is that the user must keep at least one arm inside the sphere at all times in order for the victim to remain imprisoned. This technique requires a sufficient amount of water, which can be provided by expelling it from one's mouth. Once trapped the target is unable to move or breathe while within it due to the heaviness of the water. Because of the density of the water it can be used, to a limited extent, for defensive purposes if performed on oneself. It can also be stored in scrolls as traps.
Drawbacks: The user must keep one arm inside the sphere at all times in order for the victim to remain imprisoned. It can be broken out of by techniques that expel large amounts of chakra released to disrupt the chakra flow of the prison, such as Gentle Fist Art: One Body Blow.
Combination with other techs: Can be combo'd with nearly any Water Release technique

Name: Water Clone Technique
Rank: C
Chakra Cost: 25
Force: Have 1/10th of user's stats to be applied for jutsu usage and fighting
Type: Ninjutsu
Element: Water
Hand Signs: Tiger
Range: Clones created cannot travel out of 10m from the user without it losing control
Requirements: N/A
Description: The Water Clone Technique is similar to the Shadow Clone Technique except it creates clones out of water that have one-tenth of the original person's power. Like other solid clone techniques, the clones can be used to perform tasks the user is unable or unwilling to do for themselves. The range of the clone is limited however, as it can not travel very far from the original body without losing control. Like other clone techniques, if the water clones are injured enough they will revert back to normal water.
Drawbacks: "The range of the clone is limited however, as it can not travel very far from the original body without losing control."
Combination with other techs: The water these clones are made of can be used to perform other Water Release techniques

Name: Sealing Method: Air Distribution
Rank: B
Chakra Cost: 50
Force: N/A
Type: Fuuinjutsu
Element: N/A
Hand Signs: Snake - Tiger - Ram
Range: Can be used within 2m of user
Requirements: N/A
Description: The user creates a seal and slams hand onto ground, using this technique to seal all of the air in air pockets within the earth, causing it to crumble and fall in altitude of up to a difference of 20 feet lower than it's original height. The air sealed is gathered in a ball in the user's hand, which can then be slammed into ground, and, with a half tiger seal and saying "Release", the seal can be released, pushing the air that had been previously sealed into the ground again, raising a section up by a maximum of 20 feet. The section of ground whose height is changed can be a maximum size of a 5m by 5m surface area. Starting at a 5 foot increase/decrease in ground height, every 5 feet added to the value costs 10 Chakra more, with 20 feet being 80 Chakra.
Drawbacks: The air sealed cannot be distributed into anything other than the ground
Combination with other techs: Earth release users may use the raised ground or hollowed areas in their techniques.

Approved, with the notation of this. On the last technique. If you that technique is hit with fire, you will turn into a small firestorm. (50x2) Addional force to that fire move.

I would like to note that the air is sealed in an orb in your hand, so for the firestorm to occur the fire attack would have to be able to break the B Rank Seal. I'm sure that wouldn't be too hard if they're already using a big Fire Technique but yeah.

Name: Rain Man Sealing Method: Half-Zatoichi
Rank: B
Chakra Cost: 70
Force: N/A
Type: Fuuinjutsu
Element: N/A
Hand Signs: Snake - Ram - Tiger - Horse - Half Tiger
Range: Self
Requirements: An object applicable to the face to place seal on. Must be taught by Choku or someone else who has learned this technique
Description: The user forms the necessary handseals, molds their chakra, and then places this seal on an item or accessory that can be applied to the face. This seal is used to hide/"seal" the chakra signature of a dojutsu eye, such as the Sharingan or Byakugan. Once the seal is applied to the accessory, the user must put that item over the target eye(s) they wish to be hidden. Once done, the chakra signature of the eye(s) are invisible to any chakra sensing technique or dojutsu until the seal is broken. The seal can be released by the user by forming the same handseals for this technique backwards and saying "Release". This seal also hides the physical strain visible caused by some dojutsu, such as the Byakugan's veins. Despite this, the user will still very much so feel the strain no less intense than normal from using their dojutsu. Some eyes, such as Byakugan, can still be used under this seal, as the Byakugan can see through and into objects.
Drawbacks: Once the seal has been released, the user must form a new seal over another object. This cannot be done in the same thread the seal was released. Also, the user may be tricked through Genjutsu to release the seal, or, it may be undone by other Fuuinjutsu methods. In addition, if you were to use a jutsu through the covered dojutsu, such as Susano'o for Mangekyou Sharingan, the eye would be able to be sensed even through the seal.
Combination with other techs: TBA

Unless Said Otherwise Of Course

Name: Rain Man Sword Style: Countless Drops
Rank: A Rank
Chakra Cost: 90 to activate, 10 for each summoning of a sword then on for rest of topic
Force: N/A
Type: Ninjutsu (Bukijutsu is sub type)
Element: N/A
Hand Signs: Snake -> Ram -> Tiger to activate, only needs to be performed once for the thread
Range: Can summon swords from up to 100 meters away
Requirements: Know Summoning Technique, be taught by Choku, have The 47 Crimson Swords
Description: This fighting style is designed to work with Choku's weapon, the 47 Crimson Swords. It is based on the Summoning Technique, as with this technique each sword can be summoned to Choku's hands for use in fighting. The style revolves mostly around always being on the move and being resourceful in the use of the swords and their placement on the battlefield. Whether the swords are in their case still or scattered on the battlefield, after this technique has been activated they may be summoned to hand at any time. Once this technique has been learned, The 47 Crimson Swords will have a symbol on each of their pommels, labeled with numbers 1 through 47. Once any particular sword has been summoned, it may not be summoned for another 2 posts.

As the user of this style will always have an on hand source of weapons, they have an increased level of reaction through the summoning of swords to counter any attacks that come their way. As a result of this, the user has an additional +80 Speed when it comes to reaction time, but this buff only applies to reaction time.
Drawbacks: None
Combination with other techs: Can be used in conjunction with techniques that use swords/weapons as a base (Sealing or Bukijutsu) and can be used as a base technique for future Rain Man Sword Style techniques.

Seems fine to me. Rain Man Sword Style: Countless Drops approved.

Name: Rain Man Sealing Method: Absolution
Rank: A Rank
Chakra Cost: 110
Force: N/A
Type: Fuuinjutsu/Ninjutsu
Element: N/A
Hand Signs: Snake -> Bird
Range: 20 meters out from seal.
Requirements: Learn from Choku, Have S Rank or higher in Ninjutsu and Fuuinjutsu
Description: This technique is a seal that, when placed, seals space-time within a field around the seal. This means that space-time within the seal's range cannot be altered. This effectively negates the effects or activation of any space-time ninjutsu within the field. This also includes disabling users of space-time from teleporting to a location with the range of the seal, or teleporting from a location within the range of the seal. This seal can be placed on weapons and living things. Each seal lasts for 10 posts after placement and activation. The seal may be placed in a dormant state on a surface/object/person and then activated by the user at any time. To activate a seal, the user must form the Bird->Tiger->Snake seals. A seal placed in a dormant state cannot be activated for 5 posts. To deactivate a seal early, the user may form the Tiger->Bird->Ram seals.
Drawbacks: This seal also negates any space-time jutsu the user would wish to use within the field. May not be placed on liquids or gases.
Combination with other techs: Only combination is with anything that creates a solid surface for the seal to be placed on.
