Yukiko's jutsu

Name: Silent Homicide Technique
Type:E-Rank
As the name suggests, this technique is simply a very quiet method of killing an opponent, usually from behind with a blade. Additionally, because the user is very silent, it cannot be defended against. The user will often slit their opponent's throat, preventing any cry that might give them away. Zabuza was a master of this technique, and was even good enough to track and kill opponents through sound alone.

Name: Body Replacement Technique
Type: E-rank, Supplementary
This jutsu lets the user quickly switch places with another nearby object, such as a plant (normally a section of a log), an animal, or even another person within reach, leaving the opponent open to a counter-attack. Exploding tags can be attached to the replacement for an added surprise. Fundamentally, all ninja know this technique.

Name: Transformation Technique
Type: E-rank, Supplementary
Hand Seals: Dog → Boar → Tiger
This jutsu allows the user to assume the appearance of another person, animal, or object. Fundamentally, all ninja know this jutsu. The transformation technique is considered to be among the more difficult E-ranked techniques, since it requires constant emission of chakra while mentally maintaining the form. On top of that, the user would be, most likely, interacting with the environment.

Name: Rope Escape Technique
Type: E-rank, Supplementary
Allows the user to free themselves if they have been tied up.

Name: Crystal Armor
Type: Kekkei genkai, ninjutsu, short range-defensive
Users: Guren
Rank: D
This jutsu allows Guren to become encased in a thin sheet of crystal to protect her from blunt force trauma. This armor can also aid Guren in performing stronger physical attacks. The crystal is transparent and can only be noticed by light reflecting off it.

Name: Crystal: Hexagonal Shuriken
Type: kekkei genkai, ninjutsu, all ranges-offensive
Rank: D
Users: Guren
A peculiar attack used only by Guren. The shuriken used in this jutsu are six-sided with spikes at the sides of each blade, as they resemble snowflakes.

Name: Crystal Release: Crimson Fruit
Type: kekkei genkai, ninjutsu
Rank: D
Users: Guren
Guren can create a dome of crystal to surround a target. It is highly durable from both external and internal attacks. This does not crystallize the person entrapped.

Name: Crystal Release: Crystal Needles
Type: kekkei genkai, ninjutsu, all ranges- offensive
Rank: D
Users: Guren
Guren creates long, sharp, and pointed bright pink crystals that shoot at the target at extremely high speeds.

Name: Crystal Release: Giant Crystal Dart
Type: kekkei genkai, ninjutsu, short to mid range- offensive/deffensive
Rank: D
Users: Guren
This jutsu allows Guren to create a large sharp rod attached to her wrist which she can used to impale a target. It resembles the Dance of the Clematis: Flower.

Name: Crystal Release: Jade Crystal Blade
Type: kekkei genkai, short range
Rank: D
Hand signs: Horse → Ox → Boar → Snake
Users: Guren
This technique is solely used by Guren. She can quickly form a blade made of crystal on her arm, and use it almost similar to how a ninja would use a Tanto. Blades can be formed on both arms if needed.

**crystal release weapons, needles, and shurikens last throughout the whole battle.

Name: Crystal: Giant Hexagonal Shuriken
Type: Kekkei genkai, ninjustu, offensive- all ranges
Rank: C
Users: Guren
Guren creates a giant crystal shuriken, resembling a snowflake, and throws it at the enemy.

Name: Crystal Flight
Type: Kekkei genkai
Rank: E
This allows the user to change themselves into microscopic crystal pieces that can move at high speeds to seemingly teleport the user to other places. This is a natural technique for Yukiko and does not seem to need chakra as much chakra as other transportation techniques as it is kekkei genkai related.

Name: Crystal: Hexagonal Shuriken: Wild Dance
Rank: C
Type: Kekkei genkai, ninjutsu, short to mid range
Users: Guren
Guren throws a vast amount of crystal shuriken at her opponent.

Name: Crystal Release: Jade Crystal Mirror
Type: kekkei genkai
Rank: none
Users: Guren
Hand signs: Ram → Dog → Monkey
Guren forms a large mirror in the shape of a snowflake, which she can then use to perform the Jade Crystal Clone Technique. Other than that, there is basically no other use of it.

Name: Jade Crystal Clone Technique
Type: kekkei genkai
Rank: C
Users: Guren
Hand Signs: Horse → Ram
After she performs the Crystal Release: Jade Crystal Mirror jutsu, Guren can make multiple clones of herself emerge from the mirror. These clones are made of crystal, as after Hinata Hyuga defeated one, it crumbled into many crystals. Clones made by this jutsu are also able to deceive Byakugan users, as shown in the (short) fight Hinata had with one of Guren's clones. Hinata could see the Chakra Pathway System of the clone, unlike in the situation with a normal clone generated by the Clone Technique.

Name: Crystal Release: Jade Crystal Prison
Rank: C
Type: Kekkei genkai, ninjutsu, short range
Users: Guren
This technique is where Guren completely encases an opponent in crystal. If the crystal is shattered, the victim disintegrates along with the crystal particles. In one case however, Hinata was able to surround her body with chakra before she was completely encased, thereby avoiding her getting disintegrated.

Name: Giant Crystal Spikes
Rank: C
Type: Kekkei genkai, short-mid range
Handseals: Ram → Dog → Monkey, both hands on ground
This jutsu allows the user to create giant crystal spikes that can grow up to 12 feet in height at a very rapid pace. The spikes grow in clusters of about 6.

Name: Telepathy
Rank: -
This technique allows Yukiko and Akako to communicate with each other through telepathy because of their strong bond as twins. It does not seem to use chakra as only they can communicate with each other, and no one else through this technique.
