everyone couldn't help but notice how quiet kiibo was, (and they didn't even notice that his collar message said "fuck kokichi" and "hate kokichi" except gonta cuz he noticed Kiibo's collar message)

kiibo: "..."

gonta: "are you angry at kokichi, kiibo?"

kiibo (in a dumbfounded and flustered tone): "i-i had blank face activated! How could you tell?!"

gonta (in a sheepish tone): "it wasn't hard to see.."
