User blog comment:Lacusweltfan01/My Charakter Nicknames in Owari no Seraph/@comment-36009152-20190124210903/@comment-36009152-20190125210349

Likewise thank you for explaining the brilliant resemblances as well as the good idea for nicknames! That’s actually a great idea especially when people view new anime and need to remember new characters. Like rather than remember “black hair” for say Yu, “Yu-chan” is the way to go even in non-Japanese translations!

Ah got it, see what you mean for Mika and his resemblance, “Mika” is a nickname in itself and a good one, too!

Was just thinking of “Lac-us” got to big up his name and actually how good "lake" is as a nickname! “Lake Welt” it’s like some national landmark or something haha.

“Teacher/Sensei” does seem apt for Sayuri, just the idea of a sweet gentle classroom teacher by day but also fighting savagely against vampires with a heavily enchanted sword!
