That's a Space Alien, Ain't It?!

Refusing to share her favorite idol's name with him, Momo dubs Ken "Okarun" and invites him to wait out the daylight at her place before they confront Turbo Granny again. He bursts into flame trying to pass the torii gate, so Momo flings him into the river with her powers and removes the warding talisman to let him through. Indoors, Okarun frets over his missing genitals and his fear of never making a friend, while Momo reassures him she is glad to talk about the paranormal with him.

An unfamiliar chime signals an evil spirit, the result of Momo pulling the talisman from the gate. When they try to replace it, a wall materializes inside the torii and a black mist seals the yard, summoning a towering alien that Okarun recognizes as the Flatwoods Monster, hunting their 'banana organs.' Realizing she cannot fight while also suppressing his curse, Momo frees Okarun's possessed body to move on its own, and he taps Turbo Granny's velocity to dodge and bite off the giant's fingers, though his human body coughs blood from the strain. Reading the creature's sumo-like style, Momo plans to make it touch the ground. She deliberately lets the alien batter her into the blocking wall, opening a gap just wide enough to slot the talisman back, which incinerates the monster and returns them to reality.

The episode belongs to the Turbo Granny Arc and adapts Chapter 2 of the manga. The anime adds several original beats, including Momo sending Okarun crashing into a wall while suppressing the curse, and the Flatwoods Monster moving like a sumo wrestler while venting black mist from its mouth. Numerous staging and hand-position details differ from the manga, such as Momo using her right hand in the anime where the manga used her left. The installment ends with an exhausted Momo collapsing, leaving Okarun to fall back under Turbo Granny's curse.
