The Hyakki Yagyō (百鬼夜行, “Night Parade of One Hundred Demons”) comes from Japanese folklore, and as the name suggests it is a parade run by 100 different yokai. The source material combines this concept with that of a human-like suit operated by a vast number of mischievous yokai spirits. Almost always female.
Hyakki Yokai (百鬼妖怪)
Brief: 108 yokai spirits operating a lifelike human body. For them, sneaking into human society is a game.
— Construct: Although their crew are spirits, the hyakki yokai is still an artificial creation. They add +2 to recover from being Shaken; don’t suffer Wound Modifiers, and are immune to poison and disease. Hyakki Yokai cannot heal naturally. To heal a hyakki yokai requires the Repair skill—which is used like the Healing skill only with no “Golden Hour”.
— Divided Minds: Many heads are harder to trick than one. The hyakki yokai has a +2 bonus to resist mind-controlling effects such as the confusion, fear, and slumber powers.
— “I Must Retire, So Sorry!”: Hyakki yokai do not need to sleep, and when ‘sleeping’ the crew perform repair and upkeep on the bodysuit. They can make a natural healing roll every day instead of every five days.
— Outsider: When exposed as a yokai-controlled automation, they have -2 to Charisma as non-Constructs are naturally averse to such deception.
— Skinsuit Seamstress: Hyakki yokai begin play with a free d6 in Repair.

This turned out to be a very easy conversion, most of its parts just sliding into place like it had been designed that way. I will note that I removed the option for the power suit to be intersex, as gender plays a much smaller part in this version of the rules. It should be noted the racial ability would also give you a bonus to knowledge checks based around Japan’s underground gay community, which seems very wrongly placed.
