MakubeX

Height: 160 cm

Makube was found in a sack as a child. Only his last name, Makube, is known, for it was written on the bag itself. He later came to be known as MakubeX, the 'x' symbolizing an unknown variable, and his "name" is always written in romaji. MakubeX is a genius hacker, capable of manipulating computers to do whatever he pleases. He was originally taught by Gen but swiftly surpassed him in skill.

He was raised by Gen, whom he calls Grandfather, but left home to join the VOLTS. During the VOLTS's rule of Infinity Fortress, he was one of the "Four Kings", alongside Shido Fuyuki, Fuuchouin Kazuki, and Masaki Kurusu. After Ginji Amano left the fortress, he, as the only one of the Four Kings remaining, took over, instituting a dictatorial rule; he was known at this period as the "young demon king".
