Ok so let me get this right!

Matantei Loki is the first series Then Two is Matantei Loki Ragnarok. BUT the US only has Ragnarok? I am not trying to break rules or what not (looks around) but I did see the Anime sadly only found it Dub. not Sub. So after trying so hard not to see the anime I broke down and seen in but I would so much like to read it in order that is why I am asking. I do not want to start Reading Ragnarok if its Series Two (season 2).

Haven't gotten far into Ragnarok yet, but that does seem to be the case. Ragnarok is series 2, and there's a third, "Gods of the New World". I'm guessing the anime mixes the first series with a bit of the second, so they went with "Matantei Loki Ragnarok" for it, though it seems to match mostly with Matantei Loki instead.
