Hikone Ubuginu

is an artificial hybrid Soul in service to the Tsuyanashiro Family.

Appearance
Hikone is a dark-skinned, androgynous young child with red eyes and short dark hair. Hikone usually wears a red, shoulderless Shihakushō and is barefoot. They carry their Zanpakutō on their back, secured in place by a lenght of chain.

Personality
Hikone is a very polite, childlike individual with an upbeat attitude. They are very obedient and loyal to Tokinada and Aura, frequently following every given order very monotonously. Due to their artificial creation, Hikone sees Tokinada as their master and someone very close to a father, as the same is said for Aura, which Hikone sees her as their own "mother".

History
At some point before the Wandenreich invasion of Soul Society, Tokinada Tsunayashiro had commissioned Seinosuke Yamada and Aura Michibane to create an artificial hybrid Soul. Despite Aura and Seinosuke's best efforts, and the inclusion of thousands of soul pieces, including Shinigami, Quincy, Humans, Fullbringers, and even some belonging to the Soul King, Hikone was barely alive and could not move or speak. It was only when Tokinada managed to acquire the brain of the Quincy Gremmy Thoumeaux to serve as the hybrid's core that Hikone could finally be perfected and stabilized.

Natural Abilities
Immense Spiritual Power: As an artificial Hybrid meant to mimic what Ichigo Kurosaki was naturally, Hikone possesses an immense amount of Reiatsu. Hikone was able to fight on even footing with the Espada Grimmjow Jaegerjaquez, Tier Harribel, and Nelliel Tu Odelschwanck, alongside the Sternritter Liltotto Lamperd and Giselle Gewelle, though Hikone eventually lost. Harribel even compared Hikone's Reiatsu to the Shinigami captain Tōshirō Hitsugaya, who possesses large amounts of Reiatsu himself. Due to Hikone's nature as a hybrid, their Reiatsu feels similar to that of a Visored or Ichigo. Both Meninas McAllon and Candice Catnipp agree that Hikone's Reiatsu reminds them of Gremmy.

Zanpakutō

 * In its sealed state, Ikomikidomoe is pure white, almost glowing, broadsword with black spots on it. The sword has a long handle, and combined with the blade is almost the size of Hikone. Due to being a special, inherited Zanpakutō forged by Ōetsu Nimaiya, Ikomikidomoe can only be wielded by hybrid creatures such as Hikone or Ichigo Kurosaki. Like all Zanpakutō, Ikomikidomoe has its own personality, though unusually it is able to project its voice for others to hear. Ikomikidomoe appears to be quite prideful, as it is insulted when regular Shinigami even voice the possibility of being on the same level as its current wielder. Likewise, it holds disdain for Arrancar, especially female ones, and seems to know Baraggan Louisenbairn to some degree.


 * Descorrer: Ikomikidomoe can freely open Garganta for its wielder to travel through. The Zanpakutō can do this either on command, or when it feels its wielder's life is in danger.


 * Cero Negation: Ikomikidomoe is able to nullify any Cero fired at its wielder.


 * Shikai: Unlike most Zanpakutō, Ikomikidomoe has several Shikai commands, each producing a unique effect.
 * Shikai Special Ability: Ikomikidomoe has numerous Hollow related abilities, each differing depending on which release command is used.
 * Orbit the stars, Ikomikidomoe!: Ikomikidomoe transforms into a massive Hollow arm that can attack on its own.


 * Send them to their burials, and engrave them in memory, Ikomikidomoe!: Ikomikidomoe transforms into a gargantuan Hollow noted to be around the size of the Espada Yammy Llargo or the Gillian spouting Hooleer, while simultaneously possessing the same Reiatsu density of a Vasto Lorde. In this form, Ikomikidomoe can act somewhat independently, though is ultimately still under Hikone's control. If necessary, Ikomikidomoe can instantly return to its sword form.


 * Enhanced Roar: In this form, the mere roars of Ikomikidomoe can shake and devastate a part of the Rukongai.


 * Hollow Spawning: In this form, Ikomikidomoe can spawn numerous flying Hollows to overwhelm opponents.


 * Hatch the deceased, Ikomikidomoe!:


 * Bankai: Unknown
