Abilities/Spell's: Kenatsu

Kenatsu (Sword pressure) is when Tetsusaiga, like Tōkijin, and most swords of demon origin, has the ability to cut an enemy without making physical contact. It was used by Sesshomaru in Episode 18 of the anime. It has the power to slay 100 demons. It was also used by Inuyasha in Episode 28. InuYasha can be seen using this ability before he discovers Tetsusaiga's top-end Kenatsu: Kaze no Kizu, the Wind Scar.

Kaze no kizu

Kaze no Kizu (風の傷 Scar of the Wind or "Wind Scar" in English dub) is a special attack technique that can, like the kenatsu, kill 100 demons with a single stroke. The technique is the base attack of the Tetsusaiga. This attack is accomplished by finding the fissure or scar between colliding demonic winds of Tetsusaiga's wielder and the opposing demon. Once the wind scar is found, the wielder of Tetsusaiga can swing the sword into the scar, which releases a powerful energy wave that has the strength to end 100 lives in one strike of the sword. InuYasha first used this attack by finding the location of the scar with his enhanced sense of smell, but eventually he learned to see the Wind Scar. When the wielder becomes proficient enough, the Kaze no Kizu wraps itself around the sword; allowing the energy wave to be released at will, without a need for visualizing the scar between winds. After wounding Ryūkotsusei, InuYasha gains the ability to unleash this attack wherever and whenever he wants, without the need of finding the scar of opposing winds to cut. This was especially useful against Kagura, who could manipulate the demonic winds, preventing the Kaze no Kizu from forming. However, the user has to use his own demon energy to supply the power to form the Kaze no Kizu surrounding the blade. This explains why when InuYasha confronted Musō with multiple Kaze no Kizu, he could not keep it up forever as it would drain his demon energy. It also explains why the Kaze no Kizu manifests as a much stronger attack when used by the likes of Sesshomaru and the Inu no Taishou, as opposed to InuYasha. The strength of the blast also depends on how hard and fast the blade is swung.

Throughout the series he is shown to be mostly releasing lesser versions of this attack, using Tetsusaiga's Kenatsu. The only time he is using the full extent of its power is when he actually calls out its name.

Built upon this attack is the more powerful attack called Bakuryūha, also called the Backlash Wave.

Bakuryūha

Bakuryūha (爆流破, Explosive flowing wave, Crushing stream, Dragon twister in InuYasha: A Feudal Fairy Tale (PS): , Backlash wave in English dub) is the Tetsusaiga's ōgi (or ultimate technique). This only works on foes with a large demonic power. Uses the opponent's strong yōki and the Kaze no Kizu to return the attack, magnified hundreds of times. With this movement of the Tetsusaiga, he forms enormous charging twisters that sucks the foes power into the Wind Scar and forces it to flow backwards. The wind and the power twist together into a vortex, pushing it backwards and the enemy is attacked in its own demonic force and Tetsusaiga's might combined. But to use it, he must see where to cut the yōkai's aura and have strong enough ki himself to overpower his foes. InuYasha first used the ability in his battle with Ryūkotsusei, whom he killed using it.

During the first and second movies, InuYasha used the Bakuryūha to slay the "boss" villains, Menomaru and Kaguya, respectively. He used it multiple times in the third movie, ultimately combining the attack with Sesshomaru's Dragon Strike (performed this time by Tenseiga instead of Tōkijin) to send the living sword So'unga into Hell. In the fourth movie, he combines it with the Kongōsōha attack to create the Kongō-Bakuryūha (Diamond Explosive Flowing Wave) attack.

In the manga, it is used to destroy the gigantic bat yōkai Taigokumaru, and was used against the human swordsmith Toshuu, and his ryūjin sword Dakki/Datsuki, though it failed to destroy them.

In the anime only, InuYasha uses this attack to slay the dark priestess Tsubaki (who had merged with an ogre), Bankotsu (after he had powered up his sword Banryū and gained a powerful yōki attack), and the yōkai horse Entei (with help from Kirara), and Hoshiyomi (with help from Kagome).

In the video game InuYasha: Secret of the Divine Jewel, this technique is used (by InuYasha) to counter enemy attacks and can be used on weak-enemies (the enemy must attack InuYasha or a party member), as well as Bosses. The technique's only drawbacks (in the game) are its high energy cost (its energy cost is lower than the Wind Scar) and that it can only counter one (and hit one) enemy.

Unlike other techniques in the series, Bakuryūha is the only one to be introduced in its Japanese name in the English dub of the anime; however, it is always later addressed as "Backlash Wave".

Sacred Backlash Wave

This attack is actually a combined effort between InuYasha and Kagome. It consists of Kagome firing one of her Sacred Arrows into the center of InuYasha's Backlash Wave before it connects. When it hits the enemy there is a higher chance that he will be destroyed by the combined powers. Used in Episode 140 to obliterate Hoshiyomi , Movie 1 to kill the Hyoga and in the Movie 4 to kill the Four War Gods.

Red Tetsusaiga

Barrier shatter (Red Tetsusaiga) is gained indirectly from the orb of the bat demons that gave them the power to create barriers. This technique renders barriers useless. Only the strongest barriers cannot be shattered by this attack, assumably it must be stronger then the barrier made by the orb. When being used, Tetsusaiga's blade becomes crimson red.

InuYasha learns Barrier shatter after he destroys the bat-demon Taigokumaru.

The Barrier shatter has been used the following times:

* During his fight with the Panther Devas [3]
* Piercing through Naraku's barrier immediately before hiding himself at Mount Hakurei.
* Tearing through a rat demon's barrier.
* Destroying the locks on the gate to the Netherworld, while battling the two underworld statues Gozu and Mezu.
* Trying to destroy Hakudōshi's barrier while riding Entei (unsuccessfully).
* InuYasha's last time performing Barrier shatter within the anime is against Naraku before he learns the Kongōsōha, though that is not the case with the manga.
* Attempting to tear through Midoriko's barrier which was keeping him away from Kohaku.
* Trying to save Kagome from Hitomiko
* InuYasha uses it at the beginning to break Naraku's barrier. [4]
* He uses it to enter Kaguya's fortress on the lake's surface.[4]
* Though not exactly used, Tetsusaiga's blade glows red but for no apparent reason, perhaps because InuYasha thought Kaguya may be forming a barrier.[4]
* To try and break through the barrier protecting the jeweled comb-box that held the power orbs of the Four War Gods.[5]

Kongōsōha

Kongōsōha (金剛槍破, Diamond spear wave, Adamant barrage in English dub): the attack where the blade of the Tetsusaiga pulsates and slowly forms into a whole blade of fragmented diamonds. When the sword is whipped into an attack, many shards of spear-like diamonds shoot out with the ability to penetrate any barrier, which is particularly useful against those that the Barrier Shatter cannot break.

At his father's grave, InuYasha gained Kongōsōha indirectly from Hōsenki, a crystallized daiyōkai. Hosenki told InuYasha to cut him, but when InuYasha physically couldn't (which Hosenki probably knew), InuYasha decided that, instead of continuing to try, he would save his friends from Naraku instead. Thus, InuYasha obtained the power to combine his Kaze no Kizu with the kongōseki ("diamonds") to wreak havoc on the foe, or simply to swing Tetsusaiga and fire off a huge volley of large diamond shards.

While trying to get away from an ogre's belly Inuyasha used a jewel shard to power up his Adamant barrage into a more powered up form of the wind scar barrage or the Kaze no Kizu-soha called the Golden Gun.

In the manga, the yōkai Mōryōmaru was able to copy this attack. In InuYasha's case, it can be fired with or without an accompanying Kaze no Kizu. Mōryōmaru appears to be able to use it with the same or slightly less power than InuYasha, in any case he was able to mince Naraku to the same degree.

Youki absorption / Youketsu cutting

The acquisition of the Dragon-Scaled form gave Tetsusaiga the ability to theoretically absorb limitless amounts of youki, but because of Inuyasha's nature of as a han'you, he could not use this ability to its fullest extent without incurring potentially fatal penalties. This forced him to develop another technique which enabled him to "sense" a youkai's youketsu, then cut it with the Dragon-Scaled Tetsusaiga; by destroying this source of a youkai's youki, Inuyasha can effect a sort of instant-kill upon a youkai, or if its a gestalt entity like Moryomaru, systematic destruction of the creature by the death of its component parts (which it can't regenerate).

Meidou Zangetsuha

Meidou Zangetsuha is an ability that creates a path to Hell (or a Meidou) through which to send an opponent; its perfected form is that of a large black sphere that resembles a hole in space. One can create a Meidou where the cut is made, or it can be fired like a projectile (its common application). InuYasha's father stole the ability from a yōkai named Shishinki with the aid of Tetsusaiga. However, because of the danger associated with such an ability, Tenseiga was created out of Tetsusaiga to bear it. InuYasha's father intended for InuYasha's brother Sesshomaru (a full yōkai who can withstand the terrible jyaki of Hell) to master that ability when he inherited the Tenseiga, then later have the sword reabsorbed into Tetsusaiga (thereby granting InuYasha the perfected technique).

Inuyasha later acquired this ability after Tenseiga is broken over Tetsusaiga, causing the latter to transform into a black blade that shares a resemblance to the physical appearance of a Meidou. Inuyasha then uses the new Black Tetsusaiga to re-open the Meidou to create a path back to the normal world for him and Sesshomaru. [6]

Inuyasha plans to use the Meidou against Magatsuhi but Magatsuhi dodges it with his self-Dispersion. Inuyasha also uses this attack multiple times against Naraku after he gains the complete Shikon no Tama. First against his outer body, second against Sesshomaru while Magatshi controls him and finally against Naraku but they are all unsuccessful

During Inuyasha and his allies' final battle against Naraku, the Meidou's form underwent a transformation to signify Inuyasha's true ownership of the ability, with the new form reflecting Inuyasha's fighting style and Tetsusaiga's inherent nature as a "sword that cuts". When Sesshomaru nurtured the technique it developed to reflect Tenseiga, a sword that does not cut and the nature of Sesshomaru; hence a perfect circle. Inuyasha's mastery of it reflects his sword, which is one that cuts, and his temperament. As such, the new attack consists of several blade-like Meidous being fired, cutting through anything they touch. [7]
