Past, present, future, and destiny. These form the foundation of the world and represent the power of the present. The past is eternal, representing unchanging power. The present is the era, representing the strongest power. The future is potential, representing infinitely powerful yet infinitely weak power. Chosen by the past, one becomes the master of the unchanging. Chosen by the present, one becomes the king of the era. Chosen by the future, one becomes the emperor of the end and the emperor of hope. Chosen by destiny, one becomes the emperor of fate! The chosen youth ultimately embarks on the path planned by destiny. Not wanting to be bound by fate, he continues forward. If humanity cannot achieve this, then he will become a stronger being, until he becomes an ultimate existence that even gods cannot look directly at. The world is finite, but dimensions are infinite. Continuous battles lead to becoming the ultimate being. Becoming the master of destiny! The female lead is Yae Sakura (?ω*?). Worldline: Akame ga Kill! → Fourth Holy Grail War → Godslayer → Dragon Clan → Problem Child [First two volumes are for beginners, poor quality]

This is an era where gods actually exist. Yes, this is... Greece! The gods wield their power with impunity, regardless of gender, as long as they are good-looking. This is Greece! In short... you must survive! Greek Survival Rules: First, remember who's boss here? The gods. Second, remember, don't speak ill of the gods, they can hear you.

Thirteen, don't become a hero. The pure white hope will eventually be released in Pandora's Box, the Holy Grail War.
