Sadaso (サダソ, Sadaso) is one of the three fighters that challenge Gon and Killua on the 200th floor of the Heaven's Arena. Having reached the 200th floor without the use of Nen, he was "initiated" after being attacked with a malicious aura attack and lost his left arm.[1]

Sadaso 2011 Design

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. It's unknown if Sadaso wears a mask, which is commented by a ticket seller when he's talking to Killua.[2]. When he leaves 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 mean and ambitious, willing to do anything in order to become a Floor Master. He has also been shown to be mischievous and a coward, since he quickly submitted to Killua's threats when confronted by the assassin.

Three fighters who pick on rookies

Sadaso is one of the three fighters who target rookies for easy wins to become Floor Masters, they challenge Gon and Killua on the 200th floor of the Heaven's Arena. He appears for the first time after Gon and Killua learn Nen from Wing and break Hisoka's "invisible wall" with it in order to reach the 200th floor, observing them along with Gido and Riehlvelt in the same corridor and commenting that they are capable of using Nen too. Then the three of them subscribe the day of their next fights along with Gon and Killua. After Gon finally recovers from his previous fight against Gido, Sadaso, Gido and Riehlvelt meet them again and Sadaso tries to force Gon to subscribe his fight for the same date that he chose, giving to them an example of his power in order to convince them, but Gon remains unconvinced.[3]

Sadaso threatened by Killua 2011

Sadaso threatened by Killua

Sadaso briefly kidnaps Zushi along with Gido and Riehlvelt, using his Nen ability to make him faint in order to persuade Gon to comply with his demands, namely having Gon forfeit in a match. But Killua saves Zushi promising that he will fight against them and granting one victory to each others. They accept and set Zushi free, Killua then departs with him but warns them to not break their promise. However they cheat tricking Gon, arranging a fight between him and Sadaso. Killua learns of the fight between the two and threatens Sadaso's life,[2] frightening him enough to leave Heaven's Arena for good.[4]

While leaving Heaven's Arena, he contacts Gido and Riehlvelt to warn them that Killua will come after them next.[4]

Abilities & PowersEdit

Although he should be praised for surviving a confrontation with a Nen user while still being ignorant about it and for winning fights even as a cripple, Sadaso is not a strong warrior, as he challenges only people new to Nen. He is never shown in combat in his appearances, but judging by the fact he is able to maintain his position above the 200th floor of Heaven's Arena, albeit through mostly questionable methods, it can still be assumed that he possesses a certainly above average degree of fighting prowess. He is also skilled in Nen enough to develop a Hatsu ability. However he has also by his own admission, stated that there is too great of a gap between his strength and Killua's, hence he withdrew from his match-up against the young assassin that he'd make a mistake of picking on, for fears of his life.[4]


Sadaso is a Transmuter, so he specializes in giving a specific form to his aura or changing its properties. Sadaso transmutes his aura into a large monstrous arm, in place of the one he'd lost, to attack his targets. While it is unknown how many basic and advanced techniques of Nen that Sadaso is capable of, but he may be an adept user of In, seeing that Zushi was unable to detect his presence both before and during the time when he was ambushed by Sadaso, nor was he able to see the latter's Hatsu ability, the Aura Arm.[2]

Sadaso's Nen Type: Transmutation
Type: Transmutation Aura Arm
Nen arm 2011 Sadaso transmutes his aura into an enormous left arm to replace the one he'd lost after being "initiated." Those who are enveloped by the hand are seemingly paralyzed and unable to breathe or to make sounds, eventually fainting if they fail to break free. It is unclear whether or not the paralysis is a part of the ability's effects or that the victims are merely experiencing suffocation after being enveloped by the Aura Arm, assuming the transmuted arm is also tangible. The Aura Arm also seems to be invisible even to Nen users, it's unclear whether it's just invisible or that Sadaso is able to hide it using In.[2]
