Ginko The Mushishi
Traveling Mushi-Shi
Because Soma is clueless. He will most likely think Sayogoromo is always either hungry or just sleepy, and totally forgets he's actually sick XDTrail mix? Rofl why?
Sometimes he mistakes Sayogoromo as a female too, because he isn't the smarest around. But he sure can be smart when he puts himself to the test.
Like when he created a giant chicken puzzle, but there was no reason for it.
But there was.
Because chickens.
And on that day Joseph never let Soma have a chicken puzzle again.
