Prologue

Having an adorable and precious little brother is great. It's an absolute blessing. But you know what they say, all great things comes at a price. Ieyasu was gonna learn that the hard way. Join him as he fights a neverending death battle with many people, the one who is left standing gets the innocent little sky as a price.

Ieyasu is determined to NOT lose. Oh, he was not letting anyone else have his otouto. He was his and no one else. Not even that bloodthirsty skylark, rebellious problem child, sadistic hitman and equally sadistic blue haired tsundere can win against him.
