Haruto Tenjo

Hart Tengo is the younger brother of Kite. He has incredible abilities from Barian world that Dr. Vaker abuses in order to accomplish destroying Astral World. When Hart was born, he was very frail and sick. His father made great attempts to save him and eventually made a deal with Vector: Vector will sustain Hart's life if Dr. Vaker helps him to destroy Astral world and collects the "Numbers". He has Barian powers which meant that he could teleport, create roads to other worlds and much more.
