Episode 21: 麺との遭遇 – Men to no Sōgū
(Close Encounters of the Noodle Kind)
Yuga and his friends were wandering underground to search for “heaven,” the place where Nail is located. They were exhausted and hungry. Following a delicious smell, they eventually stumbled upon a flashy ramen restaurant filled with Goha employees called “Cosmic Catering.” And the one who’s serving super delicious ramen… is an alien named Sorako?! Since ramen is involved, Menzaburo is also there, kicking off yet another Ramen Duel!

Note: I’ve changed the title from DMC’s description on their blog to more emphasize the reference: The episode is a play on the Japanese title of Close Encounters of the Third Kind, a classic movie.
