Den-noh Coil

Yuko and her sister move from Kanazawa to the city of Daikoku. Shortly after arriving, their virtual dog Densuke runs through a wall and disappears.

Yuko and Fumie attempt to cure Densuke of his virus. Meanwhile, a mysterious girl dispatches an army of tiny virtual creatures to capture Densuke.

On Yuko’s first day at school, she receives word that Densuke has been kidnapped. She and Fumie go in pursuit, but they are obstructed by Searchmaton.

Yuko tries to befriend Isako but is coldly rejected. Afterward, Daichi launches a digital attack on Isako as revenge for refusing to join his club.

Isako convinces Daichi and his pals to accompany her on a search for metabugs. Yuko and Fumie team up with Biology Club head Haraken and follow them.

Determined to find out Haraken’s true identity, Fumie and Yuko investigate Searchmaton’s programming. Kyoko wants to join them in their experiments.

Yuko and Fumie’s search for a virtual pet hamster leads them to an abandoned factory, where Isako is attempting to capture a legendary illegal.

On the day of the summer festival, Isako orders Daichi to challenge Fumie to a duel. But Daichi’s feelings for Fumie make him reluctant to comply.

The kids spend the night at school. After sharing spooky stories about Michiko, they carry out their duel while Isako continues to pursue the illegal.

Isako kicks Daichi out of the club. While helping Haraken follow some mysteriously obtained directions, Yuko suddenly remembers a boy called 4423.
