Mizuchi is a large dragon-like water deity who was encased in ice within Orochi's Ice Room. He is the guardian of the Mystic Amber. In the past, Mizuchi was the protector of a seaside village before he defected to Orochi when the village was razed in endless wars and despaired of humanity. During the process, he abandoned hope for mankind. He then froze himself, becoming the eternal protector of the Mystic Amber, until he smelled the scent of Chibiterasu and Manpuku and broke free of his icy state to devour them.
"A dragon that protects the Mystic Amber in Orochi's Ice Room.
Formerly the protector of a seaside village, he joined forces with Orochi when the village was razed in a war and he abandoned hope in mankind.
He froze himself in ice in order to become the eternal protector of the Mystic Amber. His nostrils, however, still remain active, and he will emerge from his icy hold if he gets a whiff of something delicious."
When battling Mizuchi, it is important to note the icicles over his head. The player must attack the demon encased in ice and once he is dizzy or stunned, an icicle will appear to almost fall. The player must powerslash that icicle and run towards the end of the room quickly and load Manpuku inside the cannon or else the giant dragon will break free from its hold. Using Manpuku's fire abilities will allow the player to light the cannon, sending Manpuku towards the demons head and dealing alot of damage. Once the player deals a significant amount of damage, the demon will begin to put up an ice barrier when shooting Manpuku from the cannon. Simply melt the barrier with Manpuku's hair or use Fireburst to continue on with the attack. Once the player defeats Mizuchi, Chibiterasu is able to free Shiranui and Ishaku from there cold encasement and have a nice family reunion before setting out to the Moon Cave.
