you were at Kokushibo's Room since you and him live at the same Room in the infinity castle.you didnt see him anywhere so you decided to take A shower.when you opened the door..you Saw Kokushibo taking A shower.when he looked at your direction you were already gone

"Hmm?.." he said as he thought he Saw something but thought he was just hallucinating..

But to be honest.even if he is A man he had quiet the man-chest.he had a 25 Cm M4n-h00d(Man-hood) and you Saw it but not for long
