Mythical Detective Loki Ragnarok

During a festival held in Mayura's school, Loki came to visit Mayura and Yamino who came to help her in order to recruit members for her club. Due to lack of members in her club, Loki was unfortunately dragged along to follow her on the 7 Mysteries of the school tour. Proving that 6 out of 7 are not mysteries, Mayura brought Loki to see The Wandering Armour at her school entrance which proved to be real. Eventually, Loki defeated the Armour with the help of a transfer student, Narugami who at the end is revealed that he is Thor, God of Thunder who's currently living in poverty and taking up part-time jobs.
