One a man and the other a woman/mermaid that he witnessed before. As Musashi about to follow Mari, he is knocked down unconscious. The next day, when Musashi and Mari went snorkeling, they discover a portal underwater and at the same time are ambushed by a stingray kaiju. As it starts to rain, Tutomo cowardly hides under the table with Mari mocking him, causing Tutomo to take a nearby soda and spray it on Mari, starting a soda fight with his friend as they are watched again by the mermaid. One of his friends, Tutomo, mocks him for believing in a mermaid but Mari objects it, implied that Musashi might be speaking the truth ever since his first encounter with Cosmos. Musashi attended his childhood friend's wedding and later witnessed a mermaid. Cosmos destroyed the monster, causing a giant explosion and quickly rescuing Musashi from the explosion. As they dueled, Musashi founded that the monster is responsible for turning the Planet Juran into a barren wasteland via it's energy beam. As it is about to ram Musashi's TECCH Spinnar KS-1, Ultraman Cosmos appeared and saved him. Suddenly, a flying monster burst out from the ground and firing a reddish energy ball. Not only that, Parastan, the planet's protector died. However, much to his horror, the planet appeared to be a reddish and dusty wasteland.
