Rain Leg Musha is found in the 7th, 8th, and 9th floors of Marukyu Striptease within the Midnight Channel on rainy days. It uses the skill Rebellion to increase its Critical Rate in order do score critical hits on the party. It also absorbs all attacks but Electricity (its weakness), Light/Dark (both of which will be nullified), and Almighty. It rarely drops a Zero Board when defeated. Selling the Zero Board at Daidara will unlock the Ame-Otoko male armor in the shop, which has the lowest defense of male armors available from Marukyu Striptease but adds 100 HP when worn. The Rain Leg Musha is unique from the Musha Shadows from Persona 3. It has also replaced the Hakurou Musha.
In Golden, it appears on floors 5, 6, 9 and 10 of the club. It may drop Lepidolite, Lemon Quartz and/or Olive Stone.
