MAO

Nanoka is an attuned adolescent; so when a covered shopping arcade beckons, a strange world awaits.

After an accident she experienced in her first year of elementary school, Nanoka recalls seeing a monster and realizes that the world connected to the gate of the Fifth Street shopping alley is actually from the Taisho era. Meanwhile, Mao begins investigating the “headless bodies incident,” which appears to be connected to the Byoki that cursed him.

Nanoka is unharmed by Mao's cursed sword; she returns to modern times to investigate an accident.

Nanoka and Otoya infiltrate the Shorinkyo cult, but get trapped inside by the leader, Shoko.

Frequent earthquakes strike the Fifth District during the Taisho era. Mao and Otoya hear from a Ayakashi, who had gone to check the landslide in the foothills, that a mysterious Western-style building has appeared near the keystone that once suppressed the quakes. The two head there and discover a church that wasn't there before.

Nanoka tells Mao and Otoya that she comes from a world a hundred years in the future, but they don't believe her. After returning to the present, Nanoka takes the antidote Mao gave her and suddenly recalls what happened on the day of the accident eight years ago. Troubled by her doubts, she goes back to the Taisho era to seek answers from Mao.
