Mina and Shin navigate the chaotic streets as the Imugi unleash destruction upon the city. Shin departs to help others, urging Mina to head to Lotus House. Amidst the havoc, Mina encounters the Goddess of Moon and Memory near a shrine. The goddess seeks a memory contained in a paper boat, believing that it holds Mina’s desire to be the Sea God’s bride. Mina offers the memory in exchange for the goddess’s agreement to make the Imugi withdraw.

However, the memory reveals a younger Mina expressing frustration at a goddess, not a desire to be the Sea God’s bride. The Goddess of Moon and Memory, tricked and unable to fulfill her part of the bargain, departs in sorrow, leaving the Imugi behind. Mina then finds herself in a perilous situation, surrounded by Imugi. Suddenly, the dragon, who is really a transformed Shin, arrives and battles the sea snakes. Amidst this chaos, the Sea God also appears, commanding the dragon to stop its attack. Despite Shin’s defiance, the Sea God insists that Mina fulfill her promise to become his bride. Torn between her duty and her feelings for Shin, Mina makes the heart-wrenching decision to join the Sea God, believing herself to be his true bride.
