The old woman that Yamino and Loki talk to say that her mistress-who died in a fire-used to always carry around a doll. (specifically, the doll that Mayura found). she claims the doll never left the mistress's sight. However, if the mistress [who remains unnamed] died in a fire, then shouldn't the doll have burn marks, at least? And what was it doing in the clock tower, if it never left the girl's sight?
Mayura: I need you to help me find something.
Loki: What sort of something?
Mayura: It's a... a doll.
Loki: A doll?
Mayura: (laughs) not your every day run of the mill type doll, silly goose! This doll laughs and flies and she calls me her sister. She's super cute. She's got big eyes like yours... hey, your eyes ARE big! and look how cute... (continues to ramble)
Loki: Yamino, please see this young lady out.
Yamino: (singing and digging) As long as it's for Master Loki, I reply, 'Okie-dokie!' Heave-ho!
Original Japanese Name: Matantei, Toujou!
Matantei Loki Ragnarok, in the English Dub, is translated over to "Mythical Detective Loki Ragnarok".
In the beginning of the episode, it's raining and can see Loki's shadow. When lightning flashes, his shadow grows taller, then lightning flashes again and everything goes back to normal. This is probably foreshadowing, hinting that Loki isn't as he appears to be.
According to Norse mythology, Loki is a mythical being or god, and is sometimes known as the god of chaos or a trickster.
