One day, as Guest finished training and was walking down the hallway as usual, they overheard a certain rumor.

"Hey, did you hear? Chino from that unit... apparently his ears are his weak point."

It wasn't something they intended to overhear, but the words reached them anyway. That rumor ignited the explosive curiosity within the ever-inquisitive Guest.

Guest decided to devise a plan to verify the truth of the rumor.
