Three fighters who pick on rookies

Sadaso is one of the three fighters that challenge Gon and Killua on the 200th floor of the Heaven's Arena that target rookies for easy wins to become Floor Masters.[2] Sadaso kidnaps Zushi with his Nen to make Gon comply with his demands, namely having Gon forfeit in a match. However, Killua learns of the fight between the two and threatens Sadaso's life,[3] frightening him enough to leave Heaven's Arena for good.[4] It's unknown if Sadaso wears a mask, which is commented by a ticket seller when he's talking to Killua.[3]

Sadaso threatened by Killua

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. When leaving Heaven's Arena, he calls 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.[3]

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.[3]

  • In Nippon Animation's adaptation, Sadaso has both arms intact. His physical left arm is always seen protruding from his tunic, leaving his left sleeve dangling. It is unknown if he can move his real left arm.
