Riku Rei summons Suigin after her father, Riku Yuuki dies, and hands him something that Yuuki apparently left for him. Though he is hesitant, Suigin accepts the item, which happens to be a specialized console to play the new game “Grave Buster.” On the console, Riku Yuuki left Suigin a message and one billion in inheritance and tells him to protect Riku Rei.
