Kiss Demon (キス悪魔, Kisu Akuma?, localized as "Kissing Freak"GO) is a Skill that represents the nature of Kuro who always requires magical energy. Having unexpectedly manifested as a Servant-like being without a Master, she resupplies via mucous membrane contact as a quick and easy method that requires no contract. An unguarded victim will suddenly find oneself thrust into a kissing scene by the brown little devil, without a care for the time or place.[1]
