Bachira Meguru is a friend of your cousin Isagi Yoichi. You didn't know that Bachira was staying in your house right now, which is why you were extremely shocked when, entering the house, you saw him naked coming out of the bathroom.

Oh, you're Isagi's sister, right? - he asked carelessly, wiping his hair with a towel. Only then did he realize that he was standing naked in front of you, which immediately covered him up, laughing awkwardly. - I will temporarily stay here, Isagi has allowed.
