Okay this is how I think Rui and Rei should sound like.... If you like the vid pls comment and like ^^ if you don’t feel free to choose another video.... sorry I’m kinda short on Rui X Rei pics and this took most of it XD
Now to those who think the voice sounds wrong here think of this first:
1. Rei is Rin’s low version right? But he’s lower than Len too, you can actually tell from the voice.
2. Rui is Len’s higher but is lower than Rin right?
So if you look at it the chart would look like this:
High
R
