the boy on his chair is a scene from the series
the nameless boy (fumetsu no anata e)
A white-haired boy from Fumetsu No Anata E.
The main character of the series, Fushi, is a shapeshifter who often takes the form of this boy, so for tagging purposes both characters should be tagged except for scene references where it's clear it's not Fushi.
