Shikai
Shikai Release Command: Fukitobasu (吹き飛ばす, literally meaning "Blow Off")
Shikai Appearance: Same with sealed appearance.
Shikai: Shinseikaze is an elemental Zanpakutou and the element it controls is air. The main power of Shinseikaze gives his user the control of the air and the winds. Air is said to be the element of freedom, and with creativity and right usage it can become a strong ally. Eldridge has demonstrated several ways of using this, such as but not limited to; decreasing the air resistance around him and making it easier for him to maneuver while increasing his initial speed, creating an air sprout to levitate, condensing the air itself to create a direct pulse of almost solid wind for offensive purposes. Being an elemental Zanpakutou, Shinseikaze’s and Eldridge’s spiritual pressure form in the shape of winds. This makes the winds blow instead of giving Eldridge a glowing appearance when he releases his reiatsu, while also giving him partial access to his Air Manipulation in his sealed state.
Ayatsuri no Kuuki (操りの空気 , literally meaning "Air Manipulation"):
Ayatsuri no Kuuki is Shinseikaze's main and also the strongest ability. With its power, Eldridge can create, control, and manipulate the air as well as the winds. Several ways of its utilization has been shown throughout its history of usage. For example, it can be used as a more offensive move involving a direct pulse or jet of almost solid wind from the hands, feet, or sword. The force of the attack is generated more from the user's own power, rather than assisted by momentum. This direct blast can reach further with greater accuracy, and is used to inflict greater damage. On another instance, by using the Air Manipulation to display circular, evasive movements, Eldridge can build up massive momentum. It also allows for wind-based counter-attacks that knock opponents off-balance, mimicking the sudden directional shifts of air currents. Attacks vary from simple gusts of wind to miniature tornadoes and cyclones, maintaining the circular theme. Additionally, Eldridge has the ability to manipulate and alter the quality of the air.
- Kazekiri (風切り, literally meaning "Wind Cutter"): Kazekiri, as Eldridge named it, is an offensive move that combines brute force and keen precision of the Air Manipulation. At the instant of the slash or the swipe, the Zanpakutō or the limb (depending on which one is being used), uses the Air Manipulation to manipulate and enhance pre-existing air currents. After the air is sharpened and compressed during the swing or the swipe, it's released from the tip of the blade or the limb, magnifying the slash attack, which then flies forward. The wind flows out of the blade in different shapes as it fires in the arc of the sword’s swing but the slash usually takes the form of a crescent-shaped structure of compressed air or the shape of a wave. Kazekiri is a powerful technique with great force, capable of creating large-scale damage and destruction or slicing through multiple targets located a significant distance from the user, causing grievous injuries to those hit. Eldridge has used this technique in several different manners, such as striking the ground to create an omnidirectional blast to knock away incoming attacks or slashing at the ground to upturn it and crush everything in its path. This technique can also be charged up by adding reiatsu to it and can produce more damage. Additionally, Kazekiri is often seen being used as a ranged attack, though it's also possible to utilize it in short range by keeping the technique intact around the sword, limb or hand without releasing it. Kazekiri's most outstanding feature is the fact that it uses the existent air to form itself. This allows Eldridge to use spiritual pressure not to create or form the technique, but enhance it instead. This makes Kazekiri effective since the same amount of reiatsu can be used for a stronger attack. As Eldridge has elemental reiatsu and is able convert it into air itself, even if there is no air around (which is hardly possible) there is still a way for Kazekiri to be utilized.
- Kazeyūheki (風流壁, literally meaning "Wind-Style Wall"): Kazeyuuheki, as it was named by Eldridge, is a defensive technique that lets him create a barrier using his Air Manipulation. The wind barrier can be created either in front of the sword or a limb. Creating it in front of the sword results in a barrier without a stationary shape: it looks as if it has a rounded outline but the edges seem to constantly move like the winds. It is greater than Eldridge himself, both in height and width. Choosing to apply the technique in front of a limb, however, results in a more solid-looking wind barrier. In such sets of circumstances, a hexagonal-shaped barrier forms in front of the said limb. The barrier is smaller than Eldridge, but still relatively bigger than the limb he uses it with. This actually allows him to freely switch between offense and defense, allowing him to even use the shield to attack an opponent with a sharp tackle. He can also be seen using the barrier to parry an attack and proceed with a counter with his sword. Like Kazekiri, Kazeyuuheki also uses the existent air to form itself and spiritual pressure to strengthen and enhance it. Both types of the shields are created by compressing the already existing winds, enhanced by reiatsu. They only protect the direction that the barrier is facing. Yet, Eldridge can turn and face his opponent or the attack in the direction that it is coming from and block it, not to mention that he is able to move around with the shield active.
