If I Don't Transmigrate Soon, Dad's Going to Destroy the World

Tubby Dad says, "Ten thousand years ago, I was a mighty big shot too. If I hadn't conceived and given birth to Tutu, then turned over a new leaf and retired from the world, who knows if this world would even exist." Tutu thinks Dad is just bragging again. "But, Dad, were you pregnant with me for ten thousand years? I'm only five." She slings her little schoolbag over her shoulder and opens the door. In the blink of an eye, she is back more than ten thousand years ago. Aelsius has been dealt a tragic and miserable hand in life. He learns that the pope raised him to use his blood to create a forbidden book, and that someone else was meant to be the holy son. Then his knightly friend betrays him, the saintess reports him, and at last his adoptive father cuts out his heart and throws him into the Demon Realm. Having fallen into demondom, Aelsius now wields a power of destruction even greater than before. At the lowest point in his life, he swears to make those people pay in blood, and to destroy this hypocritical, rotten world... With a fierce will to survive, the world sends Tutu from ten thousand years in the future to Aelsius. "Dad?" Faced with the cold, sinister, powerful Aelsius, Tutu is stunned. All one can do is sigh and lament, "Time is a butcher's knife." Theme: There are always people who will warm your years and bring you hope for a new beginning.
