Sadaso is a tall man with slanted eyes, thin lips, a pale complexion and a face similar to a mask. His hair is green in the 1999 anime and white in the 2011 anime. He is missing one arm due to his receiving the "initiation" to the 200th floor of Heaven's Arena. When he leaves the Heaven's Arena after Killua's threat, he is wearing sunglasses/goggles for the first time and his face looks less pale than before (just in the anime).
Sadaso is ruthless in his ambition, even resorting to kidnapping and blackmailing to get his way. He is intent on becoming a Floor Master in order to live off the money and fame of the rank despite lacking the necessary strength, for which reason he only fights opponents weaker than himself. He often speaks in a taunting or even threatening manner. When he was intimidated by Killua, however, he decided to leave the Heaven's Arena forever.
At some point in his life, Sadaso reached the 200th floor of the Heaven's Arena without knowing Nen. He was thus "initiated" by an opponent whose malicious aura attack deprived him of his left arm. Prior to fighting Gon and Killua, he totalized five wins and an unknown number of losses (presumably at least one).
Heaven's Arena arcEdit
When Gon and Killua learn how to use Nen and reach the 200th floor, Riehlvelt, Gido, and Sadaso confront them, waiting for them to register to pick them as their next opponents. When, two months later, Gon has recovered from his fight against Gido and has begun training under Wing again, the trio confronts the boys again. Sadaso declares his deadline is approaching. As a veiled threat, he offers to show them his Nen ability, but before he can do so, Gon offers to fight him on June 10th. Sadaso objects his own deadline is May 29th, but Killua cuts the conversation short and leaves with Gon and Zushi. As they walk away, Sadaso promises Gon the two of them will fight, eyeing the younger boy.
To force his hand, Sadaso comes up with the idea of taking Zushi hostage. He tails him and renders him unconscious with his aura arm, but he, Riehlvelt, and Gido are immediately discovered by Killua, who accepts to take Gon's place and give each of them a free win. They set Zushi free, and Killua departs with him but warns them not to break their promise. However, against Killua's terms, they blackmail Gon into arranging a fight against each of them. Killua discovers the fraud. On May 29th, ten minutes before his match against the boy, Sadaso already savors his status as Floor Master, but Killua appears behind him, pointing a knife to the back of his head. He orders Sadaso never to show his face to him and Gon again. Frightened, Sadaso throws his match and leaves the Heaven's Arena. As he does so, he phones Riehlvelt, informing him of his suspicion that Killua is an assassin and warning him that the boy might come after him or Gido next.
Abilities & PowersEdit
In the past, Sadaso must have been a capable martial artist, having reached the 200th floor of the Heaven's Arena without knowing Nen and without the use of weapons. However, after his injury he fought only opponents new to Nen, so his proficiency remained relatively low, to the point he was unable to sense Killua and was frightened by him, when the boy had only mastered three of the Four Major Principles.
Sadaso is a Transmuter who specializes in altering the shape and consistency of his aura. Beside Hatsu and Ten, he has demonstrated the ability to use Ren and In, since Zushi was unable to see his aura or perceive it through any other sense.
|Sadaso's Nen Type: Transmutation|
|Type: Transmutation||Aura Arm*|
|Sadaso transmutes his aura into an enormous left arm to replace the one he lost after being "initiated". Those who are clutched by the hand are restrained and unable to make sounds or even breathe, causing them to quickly pass out. It has been noted to be hard to escape from.|
