Who gives the best teeth out of the re:zero girls? (Read body text)
Now, this is a very serious question. There are multiple ways you can go about this.
I'm going to limit the options to these 5 girls: Emilia, Rem, Ram, Echidna, and Shaula.
Emilia is clumsy, and doesn't have the knowhow on gentle head. She would slip and use teeth multiple times (which is a good thing). 60% teeth rating.
Rem is soft. She won't want to give teeth since it may hurt you. It would be all tongue, no teeth. 0% teeth rating.
Ram is the exact opposite. You will be screaming in distress from her teeth tearing apart your dih. Even when you finish, she'll chew the nut out of you. 100% teeth rating.
Echidna is interesting. She has the knowledge on how to give perfect teeth, but also to give you a break if it hurts too much. She knows exactly what she's doing. 110% teeth rating.
Shaula is the hardest one, because she doesn't have any specific defining traits. If we were in Subaru's shoes, she would give arguably the best teeth, right up there with Echidna. She'd do anything perfectly for her master. But if she were to give teeth to us as we are now, it wouldn't be as precise to how we want it. She probably leans towards less teeth, though, if I were to guess. She seems like someone soft, who might give you a pleasant scrape every once in a while. 45% teeth rating.
So, in conclusion, Echidna would theoretically give the best teeth in re:zero, at least out of those 5 girls.
Let me know your thoughts.
