Ōko Yushima (Modified Soul)

is a Modified Soul born of the fusion between Kageroza Inaba & Nozomi Kujō, the personal mod souls of comatose Shinigami, Ōko Yushima.

Appearance
Yushima bears a great resemblance to Kageroza Inaba, having long green hair and brown eyes but no yellow hair and a more narrow jawline with less-define cheekbones. After being resurrected by the fusion of Inaba and Nozomi, he wears a standard Shinigami attire with a yellow under shirt, light blue gloves, and a light purple belt loosely around his waist to hold his Zanpakutō.

Personality
Yushima comes across as shy around others. Despite this shyness, Yushima cared little about being with others, believing that relying on others will only have them get in the way. He wanted greatly to prove himself to others. When he became a researcher, he took great pride in his work, becoming deeply enraged when the Central 46 canceled Project Spearhead, screaming at them while demanding a reason for why they shut down the project and doing everything he could to preserve that research.

Later, after Inaba succeeded in fusing with Nozomi, it resurrected Yushima as a Mod Soul. He then appeared before a Hollowfied Ichigo Kurosaki, looking down on him in pity. As he calmly walks pass Ichigo, the now mindless Hollow attacks with a Cero, only for Yushima to effortlessly dodge. He goes off to watch his Reigai battle with delight. His enjoyment is cut short as Hollow Ichigo finds and attacks him again. Yushima again takes little interest and subdues him with a "Kin" spell.

He releases his Zanpakutō and strikes to slay Ichigo, only for his attack to be stopped by Rukia Kuchiki. After a simple display of his new abilities, he is impressed by Uryū Ishida deducing the true workings of his blade, prompting Yushima to fight seriously. As the group launch collaborated attacks, Yushima easily dodges or records their attacks. Still feeling unthreatened, Yushima calmly explains that the reason he wanted Nozomi was to obtain her Zanpakutō's reishi absorbing power so he could make full use of his own Zanpakutō's abilities. After soundly defeating his enemies, he with a deranged expression declares that he will destroy Soul Society. Before can strike down Rukia, his attack is intercepted by Hollow Ichigo, he uses his own body to take the blow.

Inside of Yushima, Nozomi's consciousness is aware of this and momentarily regains control from her emotional state. This event causes Ichigo to return to normal, but loses his little reiatsu. Yushima, realizing that his fusion was breaking down, contacts Reigai-Nemu Kurotsuchi to bring a fusion-stabalizer medicine. Afterwards, Yushima decides that Ichigo is a threat that must be killed. Ichigo's friends come to protect him, forcing Yushima to attack them first. The group manages to set him up for the Uryū's "Sprenger", but Yushima counters with his "Hajokuri" technique, converting all the energy in the area, including the Quincy attack, into pure reishi. Yushima absorbs the energy with his blade and launches it as a powerful blast at Ichigo. At the last moment, Nozomi regains control, dispelling the blast and restraining Yushima's movements. She begs Ichigo to kill Yushima now, but he refuses as it will also kill her.

Yushima regains control and knocks Ichigo down, mocking Ichigo for his faith in friendship and brags about his solo accomplishments. Ichigo however reminds him that it took the reishi of existing Shinigami to make his army and Nozomi's power to perfect Yushima's own. As Ichigo calls him a fool for believing that he has done anything on his own, Yushima angrily knocks Ichigo back down. Reigai-Nemu appears with the medicine. When she approaches him, she suddenly kicks him back hard, revealing to be Kon inside the Reigai body. After explaining how this happened, Kon gives Ichigo a perfected Mod Soul pill of his reishi, restoring Ichigo's Shinigami powers. Ichigo then uses Bankai, ready to face Yushima.

While Yushima scoffs at Ichigo's claim of his powers being fully restored, Ichigo fiercly attacks, pressuring Yushima. As the two continue to fight evenly, Ichigo's friends join in the fight. They launch several attacks to which Yushima easily counters before taking them down again. Then, Ichigo finds an opening and shocks Yushima with his Hollow Mask. Unable to absorb Hollow-based reishi, Yushima is left winded from the attack. Surprised at how much strong Ichigo is this time, Ichigo sees through those thoughts and explains it is because he won't fight with regret. Yushima begins using his displacement powers on himself to pressure Ichigo. Seeing through Yushima's pattern, Ichigo counters and grabs Sumitsukigasa, preventing Yushima from blocking his black Getsuga Tensho and is severely injured.

Weakened, Yushima's fused body begins to break down. Refusing to let Ichigo win, Yushima actives his Renzan Hajokuri technique to destroy Soul Society. To his shock however, his own Reigai army appears to stop him, determined to protect Soul Society in their own way. Yushima tries to stop them, only for Nozomi to restrict him again, producing an energy blade to stab their body. At the cost of themselves, the Reigai are able to destroy the structure and end the technique. As Ichigo's powers begin to faulter again and deactivate his Bankai, Yushima demands to know why he can't defeat Ichigo.

Finally begining to understand the concept of friendship, Yushima attacks madly at Ichigo, who represents everything Yushima detests. Despite the relentless attacks, Ichigo easily fends off them off, repeatedly knocking Yushima off balance, his Zanpakutō out of his hand, and ultimately shattering the blade all together. Refusing to accept defeat, Yushima even resorted to grabbing a broken shard to attack Ichigo with, forcing Ichigo to deliver a critical blow across the chest and finishing the fight. Also in doing so, it causes the fusion to end and restore Nozomi and Inaba.

Zanpakutō

 * His Zanpakutō takes the form of an ordinary katana with a golden hilt with a red cloth-wrapping and maroon sheath. It has a rectangular tsuba with a cross shape embossed on it. As a Shinigami, Yushima wore it on his sash. As Mod Soul, it is attached to a loose belt.


 * Shikai: When released, the katana turns into a double-headed voulge with red markings on it. With the combined powers of Inaba and Nozomi fused, Yushima's Zanpakutō becomes an amalgamation of both their swords, having Raiku's form but with more blade protrusions on the back end of both blade tips similar to Arazome Shigure.


 * Shikai Special Ability: Duplicating an adversary's attack and reproducing it is the power of "Raiku", absorbing an adversary's spiritual pressure and turning it into one's own is Nozomi's "Arazome Shigure". Sumitsukigasa possesses the power of both. "Raiku" consumes a great deal of Yushima's spiritual pressure and entails a risk when reproducing an adversary's attack, but with the power of "Arazome Shigure", He is now able to absorb the attack and continue to counterattack indefinitely.


 * Spatial Displacement: His Zanpakutō takes slices of space and recreates them. While it appears that he is manipulating time that is not what he does at all. He uses his Zanpakutō to recreate a space that didn't exist before and shifts his location in space in that instance.


 * By using the release command . Sumitsukigasa glows yellow and transforms further gaining a large hoop with multiple bladed protrusions along the outside of it. The hoop is set into the middle of the of the voulge bar where the weapon is commonly held and twirled.


 * Attack Duplication/Reiatsu Absorption: By spinning Sumitsukigasa right the central hoop glows pink allowing Yushima to absorb any attack that his Zanpakutō comes into contact with. When he spins Sumitsukigasa left the central hoop glows pink and fires the absorbed attack back. This is the true power of his Zanpakutō.


 * Hajokuri: By striking Sumitsukigasa into the ground, an elegant fortress wall of purple reishi is formed. The wall transforms all energy around it into reishi, condensing it into a green ball before getting launched as a considerably powerful wave that decimates everything in its path. The wave can dispel even after it is launched.


 * Renzan Hajokuri: A more powerful variant of Hajokuri, Sumitsukigasa produces this ability which surrounds Yushima and forms an elegant fortress of green reishi. There are also various tendrils around the fortress which latch onto the ground beside it. A huge green light shoots into the sky, casting a Celtic-like symbol above Seireitei. This then proceeds to absorb the reishi that makes up Soul Society, and can fire concentrated green blasts of energy capable of destroying a large area within its blast radius. It can also block most external attacks.


 * Bankai: Not Achieved

Quotes

 * "Loneliness is not a sin, no matter what the circumstances, I don't need help from others. Other people only get in the way. To help is mere pity. It is jealousy towards the strong. An insult to a noble spirit. To be alone is to be the only one. The privilege of a superior soul."
