I wanted this to be a just a sketch at first (hence the hairy lineart), but then I bullied myself into drawing a background, because I can't draw backgrounds, so now it's... this. Something inbetween, not quite a sketch, not quite a fully rendered artwork.
lotte is jewish because she has so much in common with me so one more thing won't make a difference. also i love her so much so why not.
leichwein/reichwein (i use the first option because of the french dub, by the way) is jewish because i love him (he's my top 0 character in monster which means he doesn't even need to be in any ranking) and i love father figures characters so i decided he's a jewish grandpa because the "old jewish man™" vibes are there !! also his name may be german but it got jewish vibes to me, as a non-german obviously. i like to think there's a menorah in his house as well as a mezouzah.
runge/lunge is jewish TO ME !! tbh i don't headcanon him as jewish that seriously because he feels very "german white man" BUT i really love him so he's a german jewish man now (very secular tho, obviously).
karl is jewish and like that's the most sure i am with (r/l)eichwein. but my headcanon is a bit complicated so bear with me. so, to me he is jewish but by adoption because both schuwald and helenka nováková don't feel jewish to me (helenka feels more jewish than schuwald though). but "neumann" is a common ashkenazi jewish name, especially among german or yiddish speaking communities. and the neumann couple, who are very cute btw, have old jewish couple vibes. also i feel like karl has lebanese vibes (i extrapolate in the tags) to me, and as a girl of lebanese jewish descent, some lebanese people are honorary jewish (ex. : tony shalhoub).
also i like to think mr. rosso as italian jewish because why not ? i love mediterranean jews + what i said about leichwein/reichwein.
same thing for the fortner couple. the difference is that i don't headcanon them and rosso that much as jewish.
