The episode opens with Momo's grandmother, Seiko (also known as Hoshiko), appearing on a TV show as a spiritual medium. She reads the fortune of a young idol, Santa Dodoria, who contradicts her predictions, denying her claims about his age, love of curry, and family status. The idol calls her a fraud, and the show's crew questions whether the program should even air due to her inaccurate readings.

After the show, Seiko takes a taxi home. Meanwhile, outside Momo's house, Okarun (Ken) is possessed by the antagonist Turbo Granny, who uses his body to attack Momo. Turbo Granny grabs Momo by the leg, but suddenly an explosion occurs when a marked brick and a warding nail collide mid-air, throwing Okarun's possessed body into a nearby creek. Seiko arrives just in time to confront Turbo Granny.

Seiko immediately challenges Turbo Granny to a fight. Using her psychic powers, she creates a supernatural barrier circle on the ground that burns Turbo Granny if she tries to cross it. Armed with a bat and her "charm nails," Seiko fights Turbo Granny step by step: she blocks attacks, traps the demon inside the fiery barrier, and counters with precise strikes. Turbo Granny warns that if she is burned, Okarun will die, but Seiko remains unfazed and continues to hold her ground, successfully keeping Turbo Granny contained.

After the battle, Momo wakes up in her room, worried about Okarun's condition. She goes to the living room and finds Seiko watching a TV show called Bakatono. There is visible tension between Momo and Seiko, as Seiko still harbors a small grudge against Momo for previously dismissing her psychic powers. Momo apologizes sincerely, bowing her head.

Seiko instructs Momo to visit the main shrine to check on Okarun. Momo rushes there and finds Okarun safe and eating inside the shrine. Seiko explains that Okarun will be fine as long as he stays within the shrine's protective boundaries. Momo updates Seiko on Okarun's situation and reveals that she has also developed psychic powers.

The episode ends with a twist: the idol Santa Dodoria's earlier prediction about his age and secret love child turns out to be true, confirming the accuracy of Seiko's psychic abilities despite initial doubts. This revelation adds a layer of complexity to the spiritual and supernatural elements surrounding the characters.

The episode "It's a Granny vs. Granny Clash!" ends with Momo's grandmother Seiko successfully defeating Turbo Granny, who had possessed Okarun. Seiko traps Turbo Granny in a protective circle and warns her, while Momo learns that Okarun will be fine if he stays inside the main shrine. The episode closes with Momo and Seiko discussing Okarun's condition and Momo's psychic powers.

Expanded narrative of the ending scene by scene:

The climax begins with Turbo Granny, the antagonist ghost who had possessed Okarun, attempting to harm Momo Ayase. Turbo Granny, controlling Okarun's body, grabs Momo by the leg, but suddenly an explosion occurs. This explosion is caused by a warding nail and a marked brick colliding in mid-air, which disrupts Turbo Granny's attack and sends Okarun's possessed body into a nearby creek.

At this moment, Momo's grandmother Seiko arrives. She is a tough, no-nonsense exorcist with spiritual powers. Seiko confronts Turbo Granny, who tries to attack her from behind. However, Seiko anticipated this and had prepared a trap: a circle drawn on the ground that acts as a spiritual barrier. When Turbo Granny steps into the circle, she is burned by a burst of flame that Seiko conjures, forcing her to retreat.

Seiko then challenges Turbo Granny directly, wielding a bat and using her supernatural barrier to fight. The battle is intense but Seiko's experience and power prevail. She whacks Turbo Granny with her bat and warns her that she predicted the ghost's moves and will not tolerate further attacks.

Meanwhile, Momo wakes up in her room and goes to the living room, where she finds Seiko watching television. They discuss the recent events, including Momo's spiritual hotspot adventure with Okarun. Momo expresses concern for Okarun's safety, but Seiko is reserved and holds a slight grudge against Momo, which Momo acknowledges with an apology.

Seiko instructs Momo to visit the main shrine, where Momo learns that Okarun is okay but must stay inside the shrine to remain safe. Seiko explains that Okarun's spiritual powers remain but are limited, and Momo updates her grandmother on Okarun's condition. The episode ends with Seiko telling Momo that she can also use her psychic powers, hinting at Momo's growing abilities.

Regarding the fate of the main characters at the end:

• Seiko (Momo's grandmother) remains the protector, having defeated Turbo Granny and secured Okarun's safety.

This ending scene emphasizes the protective role of Seiko, the ongoing threat of Turbo Granny, and the developing bond and powers of Momo and Okarun.
