• Nai Hyuga killed the cult leader with an ice spike, and one cultist killed another for showing fear.
• The surviving cultists rallied and charged Nai Hyuga with whip-like weapons, so she used Ice Release: Ice Mist and filled the area with freezing mist.

Yui summoned Xiao You to examine the evil god’s Cursed Seal and learned that it could eventually let Evil God Nami possess her. Xiao You could not seal it with her current abilities, so Nai Hyuga urged them to seek sealing techniques in the Land of Whirlpools, though Yui said there was time.
