The anger which the man felt while dieing brought him back in the form of this demon, which's only goal is to kill those who go against it. It's skilled at Suiton, it's name representing it's elemental affinity. It's only 3 meters high, refered to as the "little brother" amongst the oni. It's physical attack and defense aren't as strong as the other's but it's exceptional at speed and agility, making it a difficult target to hit.
