Matantei Loki Ragnarok

Loki is abducted by two bank robbers on the street who kidnap him after he discovers their true identities. Thanks to an earlier conversation between Mayura and Yamino, Loki decides to let them come and rescue him, rather than getting himself out of the situation on his own. He leaves them several clues and Mayura and Yamino hurry to find him before something bad happens. There is also a reference to Yamino's true nature--as Loki's Son!
