He rarely leaves his room, preferring the glow of his monitors to the outside world. Arrogant yet Cowardly: He is incredibly prideful about his intellect, often acting smug and looking down on others (especially his younger brother, Killua).

But he love his girlfriend a long and love spoiling her and being a bit perverted
