My guess on that is it comes from "Ewige Liebe" so "eternal love". But maybe not.
The other also are very strange but it has the feeling of making names out of words.
"Schutzelia" is something like "Protectia", same for "Frühtrüne" but here "früh" only means "early" but It should be the "Früh" from "Frühling" so it's "spring".
The only normal name/word is Leidenschaft which means "Passion"
@DoNotMindMe if I recall, we spent an entire night debating on that, even with a JTL who's of German native :v Eventually we asked Kazuki sensei on Twitter and got the spelling confirmed as is, but the meanings are beyond us :v
