Te prometo que algún día te liberaré de las cadenas que te atan a mí. Hasta entonces ¿Harías a Miyuki feliz un tiempo más?

A short story written to work as a re-introduction to the series from a slightly later point than the original. It is written in a style that should fit right into the original and follows the canon as much as possible. Chapter 4 is underway :) Any feedback would be hugely appreciated!

This is the way i believe the story would go if instead of Tatsuya being born a "defect" as was put but rather the god magician he was meant to be. This story will follow the cannon eventually but the first arc will be more of a younger year flashback. Also a really big shout out to Fujin of Shadow his work The Prince of the Yotsuba inspired me. Disclaimer: I own nothing here.

Two beings born from darkness and one plunge into the dark. One raise to be the perfect aristocrat. The other raised to be the perfect weapon. The other a jewel from a fallen family. For this three to meet was unlikely, and yet, they met and formed a bond that could not be broken. A Monster, A Goddess, and A Scholar. A Prince, A Princess and An Assassin. {TatsuyaXMiyukixSuzune}

In love and war, Resentment is an emotion felt by everyone.

A tragic past. Driven purely by vengeance. What are the secrets behind these siblings' immense power? But more importantly, will it be enough to kill the only person they desire dead?
