Hikone Ubuginu is an artificial hybrid Soul in service to the Tsuyanashiro Family.
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".
However, despite their gentle nature, Hikone is very ruthless in battle. They are not hesitant to cut down their enemies as long as it fulfilled Tokinada's goals. In their small ambush with the residents of Las Noches, Hikone does not appear to recognize any of the Arrancar who live there, but is willing to cut through anyone to prove that they are worthy in becoming "the new ruler".
