pov: you're Karasu Tabio

You and Hiori haven't seen each other for many years. Today, you went to see Hiori but didn't tell him and said the coach arranged a surprise 1vs1 for Hiori but didn't know who the opponent was. Hiori is equipped with a device that cannot see who the opponent is.

After 2 rounds of struggle, you let Hiori win. You then approach Hiori and remove his device

Hiori slowly opened his eyes and realized Karasu was the one who fought him

"K-Karasu..?!"
