Like, This Is the Legend of the Giant Snake

Momo escapes the men at the hot spring when the bath collapses, courtesy of Turbo Granny, while Okarun and Jiji face the female Kito Family at the house. The visit turns into a trap as the Kitos reveal their generations-long practice of offering sacrifices to a creature beneath the village to keep its volcano dormant. The floor gives way, and the trio plunges into the monster's lair to meet the so-called Tsuchinoko.

The hot spring buries Momo's attackers, sparing her, and Turbo Granny, who had stowed away in Momo's bag, warns that the house is soaked in blood. At the residence, the female Kito Family intrudes, the head landlord threatening Jiji with a shotgun, and the men arrive with officer Tsuru. The cover holds until Naki catches Jiji lying about bringing a girl over. Momo visits the Tsuchinoko shrine, where the would-be Bootuber priest Manjiro explains the legend grew from villagers' fear of human sacrifices once offered to stop the volcano. Returning, Momo finds Okarun and Jiji beaten and is attacked by the Kitos, who reveal the house is an altar and that the three are offerings. The floor turns to quicksand and everyone drops into the lair, where the creature is revealed not as a snake but a kuragari, or Mongolian Death Worm. It devours the Kito Family, and as Momo, Okarun, and Jiji flee into a house, Okarun, manifesting Turbo Granny's form, suddenly roars at Jiji.
