[Tutor] About the Good-For-Nothing I Have a Super Pretty Girl Sister

My name is Sawada Tsunayoshi, I am an ordinary junior high school student. The only thing that is extraordinary is... My sister is a super beautiful girl, the kind that sparkles! The most outrageous thing is her lucky value xe, which is in sharp contrast to his lucky e! And... "Welcome Yuriko-sama and Prince Tsunayoshi to their close coexistence", you will definitely be bitten and killed if you shout this. Please be concerned about his life and safety as he may be assassinated at any time! However, no one cares what he thinks—— She/they only care about whether Her Highness Yuriko is happy today! ! ! Intention: I'm really sorry for being such a loser...
