Your doppelganger... I wonder...But as of late... I've realized something.I came up with the name myself.The edge of the endless world...
And the color of your name.
TN: Yakumo means "eight" or more metaphorically "countless" clouds.
Yukari and Sumire are both variations of "violet/purple".Usami-san. What if your copy...was actually Renko?
