Water God's messenger descends into the ocean to collect Kiria, the fishes’ sacrifice to the Water Dragon God. However, the Diabolos mage, believing it to be one of the Five Dragon Gods, engages the messenger in combat. The serpent launches a series of attacks at the Dragon Eater, but its attempts are futile as Kiria ultimately uses her magic to slice its body. Some of the messenger’s flesh is consumed by Kiria afterwards, only for the latter to realize it was not the real Water Dragon God. Its true identity is later revealed by Kashima.
