[Duda] Es posible el sello maldito de Orochimaru?

[Aotsuki Ayame]

Orochimaru performed various experiments on his prisoners, some being fellow Konoha shinobi he kidnapped. He used them as human guinea pigs to develop techniques that would grant him immortality, the end result being Living Corpse Reincarnation. Some time later, Orochimaru was at the outskirts of Kirigakure as he found Kimimaro, the sole survivor of the Kaguya clan. Soon after, thanks in part to Kimimaro, Orochimaru's research on the source of Jūgo's powers led him to find the Ryūchi Cave and master senjutsu.[19] Unable to enter Sage Mode because of the fragility of his host body, Orochimaru instead developed an alternate method of harnessing his senjutsu chakra through cursed seals, which he tested on Anko and several others before eventually using the finalised versions on Kimimaro and the Sound Four.

Tal y como ha dicho Akame, para hacer algo como esto necesitarías (1) mucho nivel, (2) mucha inteligencia, y (3) mucho nivel de Senjutsu. Y, por supuesto, que sea aceptable y balanceable en el Tribunal.
