Rin has a total of 13 unlockable special moves. New moves are unlocked upon collecting a certain amount of scrolls. Scrolls are earned through successfully stealth killing enemies. Collect more than 1600 scrolls with Ayame and Rin to unlock Ayame’s hidden Tenchu and Tenchu 2 costumes (the amount of scrolls are added, means it is enough to collect 800 scrolls with Rin and 800 scrolls with Ayame).

Fang Guard (Ninjutsu Block)
Press circle just before an enemy attacks you, to parry attacks.
You can push the enemy off balance with this technique and leave him open for a counter attack of yours. If you fail to block right in time, your enemies’ attack will go through unblocked.
Scrolls required: 10

Arrow Block
Press circle just before an enemy projectile hits you. Deflect any incoming enemy projectiles. It is thought that ninjas possibly possessed this skill, but it seems unlikely, as it would have been more effective to dodge arrows, and continue, rather than stop and block.
Scrolls required: 30

Death Drop
After the second attack in a combo, pull away from the enemy with the left analog stick, then press the square twice (for example square, square, down+square, square). Catching an enemy while in the air, this technique allows Rin to drive them into the ground, without a chance to recover. With that amount of force that the enemy hits the ground, they are almost guaranteed not to survive.
Scrolls required: 60

Wall Run
When jumping toward a wall, keep the x button held down to run up the wall. Release the x button to perform a wall jump.
With this technique, ninja can jump toward a wall, then continue to run up the wall. It requires great leg, stomach, and even back muscles to keep balance and perfect this technique.
Scrolls required: 100

Hawk Eye (Ninja Vision)
Hold L1 and push the right analogue stick forward to zoom into your surroundings. Hold L1 and push the right analogue stick downwards to zoom out. Can be combined with using the left analogue stick to freely look around. Hawk Eye allows you to aim items more precisely and throw them farther, by zooming into your target. Legend says that the ninja had eyes as acute as a hawk’s. Whether this was due to training or use of tools is not known, but perhaps it was a special skill like this that gave them this power.

Crimson
During a throw, rotate the left analog stick 360 degrees and press circle. During the arm break, move the left analog stick down and up and press circle again. This technique was described in an ancient tome as such: “To destroy the body, you must destroy that which supports it. Destroy your enemy’s bones, and he shall not move. But crush his skull, and he shall not awaken.”
Scrolls required: 200

Numbing Strike
Paralyze enemies and innocents by pressing circle when you are in stealth kill range. This will only work on guards in ?-mode. By applying pressure on a specific pressure point, a ninja can temporarily shut down an enemy’s nervous system, effectively paralyzing them for a short while. The victim will not be able to see or hear for the durations of the paralysis.
Scrolls required: 250

Shadow
Press R1 + left analog stick (push down the left analog stick) to turn invisible for 5 seconds. You can’t attack or use items while being invisible. Useful to sneak up on enemies and to stealth kill them right at the moment you turn visible again.
Scrolls required: 300

Long Claw (Grappling Hook Combo)
This technique will require some time to learn, so be patient. Rotate the left analog stick 360 degrees (try to make a perfect circle) and press square. After the enemy is launched into the air, press triangle to grab the enemy with the hook.If you press triangle too late the grappling hook will shoot out, but won’t cling to your opponent and pull him/her back, because he/she is already laying on the floor. Using the grappling hook, this technique allows you to attack enemies after they have been knocked back.
Scrolls required: 350

Spider’s Nest (formerly known as Cling to Ceiling)
Equip your Grappling Hook and aim it at a ceiling by pressing triangle. Hold R1 and release triangle, but don’t let go of R1. Your character will be pulled against the ceiling and hang there as long as you don’t release R1, but not longer than 18 seconds. After 15 seconds your controller will start vibrating, this indicates you have 3 more seconds until you will fall down. While you are clinging to a ceiling you can still use the following items: Decoy Whistle, Grenade, Poisoned Rice and Smoke Bomb. For example try dropping a Poison Rice, when an enemy approaches to pick it up drop down on him/her and press square to kill him/her.
Scrolls required: 400

Sniper
Select a shuriken from your items, and press triangle to throw it. If you aim correctly and hit the enemy’s head from behind, it will cause instant death. In addition to the Hawk Eye technique, a ninja can further train her eye so that she can strike at enemy pressure points and vital organs with a shuriken, even at a great distance.
Scrolls required: 450

Mimicry (Mimic Animals)
This ability works exactly like the Grandmaster item Decoy Whistle. Press R1 and circle together to make an animal noise. You have no influence on what animal sound will be mimicked. Alerted enemies (?!-mode) will calm down and stop looking for you (?-mode).
Scrolls required: 500

Crimson Final
This works like the Crimson special move, but requires you to additionally press square at a specific time. During a throw, rotate the left analog stick 360 degrees and press circle. During the arm break, move the left analog stick down and up and press circle again. During the neck break portion press square.
In the last stage of the Crimson attack, a master ninja can crush her enemy’s skull in such a way that nothing could ever revive him. It is truly a fearsome technique.
