I, a Descendant of a Noble Family, Was Reincarnated as the Older Brother of a Villainous Daughter, I Tried to Educate My Younger Sister to Avoid Ruin, and Ended up Giving Birth to the Cutest Bro-Con Young Lady Ever

Foolish children are the cutest, aren’t they?

My name is Ren Saionji. I am the eldest son of the Saionji family, one of the four great noble families.

One day, when my father introduced me to my stepmother and my half-sister, Kikka, I suddenly remembered that this was the world of the hit light novel from my previous life, “The Bride of Shirayuri.”

If things continue as they are, our family will fall into ruin because of my villainous sister, Kikka Saionji. To prevent this, I decided to give her proper and healthy education to grow her into a pure, righteous, and beautiful young lady!

This is the story of me, who thought, “Isn’t this just a mob reincarnation?!” I, an ordinary guy in my previous life, even ended up summoning the strongest guardian beast, the White Tiger. With the power of Inou, I became the strongest of my time. While shouldering the expectations of those around me, I dedicated myself to educating my sister to avoid ruin. As a result, I ended up creating a noble young lady who is overly obsessed with her big brother to a slightly concerning degree.
