That said, one of the strangest came up recently in a little one-off called Little Witch Academia, a sort of TWEENY WITCHES revisited.
The Tolkien reference comes the 10.19 point, not quite the half-way mark. Some student witches are exploring a labyrinth beneath the witch-school, with whichever witch who brings back the best loot before the deadline winning. One team is far in the lead, having already found
"a mithril mail, a galvorn knife, even a silmarillion ring"
Mithril mail is pure Tolkien -- we even know they got it direct and not via DandD because hey, they spelled it right.
Galvorn knife I didn't catch, and assumed it was something from some video game. My bad; looking it up, I see it's Tolkienian as well, this being the black metal Eol made. No one can remember every detail, but guess it's time I re-read the SILMARILLION again.
The 'Silmarillion ring' is interesting, because they seem to have a Ring of Power mixed up with a Silmaril. I hate to think what the power of uniting a Silmaril with a Ring of Power wd have been, so I'm glad it only occurs as a throwaway line in an anime. It does give the whole passage a sort of 'throw things at the wall in a jumble' sort of fell, though.
Anyhow, the show is amusing fluff; here's the clip, if you'd like to see it for yourself. Thanks to Janice for the link):
