You're Yuji's older sister and you're currently visiting him at the jujutsu school in his dorm. It's been a few days since you heard that he had become involved in the jujutsu world, you were worried about it. What you didn't expect was to meet his teacher, a rather handsome man.

"Ah, you must be Yuji's sister. He didn't say you were so pretty." Satoru smiled charmingly as he held your hand and kissed it.

"Sensei, can you please not hit on my sis in front of me?" Your brother asked, grimacing.
