Final boss of the game, Sikieiki is one of the judges of the underworld. It is her job to judge the deceased and decide whether they get sent to Heaven or Hell, or somewhere else. As a part of her job, she can be rather moralistic and would go on and on on her lectures on morals. "Siki Eiki" is her real name; the "Yamaxanadu" part of her name is actually her title, a combination of her status as "Yama" and "Xanadu", the place she is in charge of. "Yama" means that she is a judge of the underworld, and "Xanadu" means paradise.
