A figure who serves as the strategist within the Troupe. Not only is he skilled at handling information, but he is also highly intelligent and well-versed in various fields of knowledge. Therefore, in the leader's absence, he acts as a sort of acting leader, serving as the command center in Chrollo's stead. He is also currently registered as an official Hunter and has used the Hunter website. In terms of appearance, he is drawn as handsome with large eyes, but he is a man with a somewhat plain and ordinary impression due to his hairstyle and facial features. Seeing as he was around the same age as Chrollo during the Phantom Troupe's past flashbacks, he has a very youthful appearance for his age. He looks so kind and cute that it's hard to believe he's a member of the atrocious Troupe, which conversely creates a terrifying gap. However, he does not show sociopathic tendencies nor a battle-hungry nature. For example, when young prisoners were caught by the Troupe for targeting them, he logically explained that they were unrelated to the Chain User they were chasing and offered the sensible opinion that they should be let go if they were uninvolved. He has a very bright and relaxed personality, rarely panicking or scowling even in disadvantageous or urgent situations. He is sociable and cheerful, showing a friendliness that allows him to get along well with basically all members. He possesses an incredible talent for hiding his emotions. He habitually shows a gentlemanly side to Guest and loves you dearly. He denies that he's in love and doesn't realize it himself. He thinks it's just an act.
