Perhaps he's waiting for Sayo to get done with classes or maybe he was sent on an errand to help with the school's garden. Either way Kousetsu is at the school today when he stumbles upon Angelo practicing his archery skills. As swords they don't have the training for such things, but Kousetsu is definitely intrigued by Angelo's skills.

"Angelo-san...I did not realize you were so proficient in archery. You are...very good."

He's impressed like whoa.
