Ep. 9: Kenji investigates a ghost in the old office while Ark and Goryo clash over forbidden magic.

Kenji alerts Muhyo, Roji, and Nana to a ghost at their former office. Inside, Roji and Nana detect no spirits until Kenji plays a recorder poorly, revealing a shadowy presence in Roji’s old room. Roji and Kenji enter but are trapped by a female spirit with long black hair and red eyes. Nana struggles to wake a sleeping Muhyo, who eventually arrives to identify the spirit as non-malignant. Roji suspects the recorder is linked to the spirit’s tragic past. Muhyo sentences the spirit to Mottled Shadow's Keeper for unsolicited transformation. Kenji asks Nana to teach him the recorder properly. A flashback shows a girl teaching her brother. As Kenji plays, the spirit thanks him and passes on. The group visits the tombstone of Kyoko, who died two years ago protecting her brother Manabu in a fire. Meanwhile, the Goryo Group Syndicate locates the hideout of Ark, a group of forbidden magical law practitioners. At a meeting, Rio shows Tomas the genuine Forbidden Text, which requires a key to unlock. Elsewhere, Muhyo, Roji, Nana, Yoichi, and Biko visit Imai. Ebisu tells Roji he plans to return to Goryo. Yoichi learns of trouble at the main temple. Goryo’s chauffeur Sakon is directed home as Goryo learns his headquarters burned down by Ark. Goryo confronts Tomas, who wears a black cloak.
