kakakakaito1998 is a MIDI blacker that blacked some of the original MIDIs that the Black MIDI Team utilizes, but keep in mind that many other MIDIs were used as well. Although a lot of the MIDIs the team makes are from kakakakaito1998.. He was not originally in the Black MIDI Team but most of the MIDIs the team blacks derive from his MIDIs. 

As of January 20th, 2019, he deleted all his videos in his YouTube channel.
