Bisuke is a 57-year-old Nen master who looks like she's barely into her teens—something she definitely uses to her advantage. She's best known for picking up Gon and Killua's training after Wing left them during the Celestial Tower arc, and she takes her role as a teacher seriously, dropping the cute act entirely when it comes to instruction.
Outside of teaching, she's a Treasure Hunter with an obsession for rare jewels. Fans often note her habit of naming the gems she collects and getting genuinely excited whenever she finds something valuable. Money motivates her too, though the jewels are clearly her real passion.
What makes Bisuke interesting is how deliberately she plays people. She leans hard into her youthful appearance and sweet demeanor to gather information, get what she wants, or even gain the upper hand in fights by seeming harmless and innocent. Most people drop their guard around her instantly. But the moment she's in teacher mode, that innocent persona vanishes—she becomes sharp, demanding, and all business.
