Imabayashi enrolled into Eitoku Academy about two years prior, possibly making him a high school senior. He had not paid tuition in ten months nor had he donated any funds since his enrollment. The Correct 5 confronted him about this and subsequently handed him a withdrawal notice. He tried to ask for a few more days, but Haruto Kaguragi refused.
Imabayashi was what most would call normal or average. He had short, slightly disheveled hair that reached just above his ears. He was only seen wearing Eitoku Academy's regular student uniform.
