On April 10 4002, Rokland Tate took Takao Konishi, an Archie who the Earth guided him to, inside the Japan crash site to search for a hidden chamber.
A day later, they reached the vault where Grandmother kept the Blood of Heroes and Rokland told Takao to slice open his wrists to decrease the volume of his blood so the pressure would not rupture his arteries after he injected himself with the blood.
