Marco Diaz is just your average 15 year old high school student. That was until his parents tells him that their family were protectors of Mewni, and he was tasked to go under the request of the royal family. How will Marco adapt to living in a world of magic. What foes and challenges will he have to conquer, and how will he become the famous "Red Knight of Mewni."

La malvada princesa Star Butterfly ha sido exiliada a la tierra, luego de un fallido intento de derrocar a la reina Moon Butterfly. Siendo enviada a residir junto a la familia Díaz, trabando una inusual amistad con Marco Díaz. Ambos deberán sortear diversas situaciones, principalmente hacer frente a los siniestros familiares de la princesa y enigmáticos seres extradimensionales.

Marco no era alguien estúpido, sabia que esa capa no la merecía, que no había hecho nada ni por el reino ni por Star. Ahora de vuelta en la tierra él jura hacerse mas fuerte, jura ser de utilidad para Star cuando la vuelva a ver... Y que amable es el destino con él pues ahora tiene ese poder, el poder para ser de utilidad./ (La portada es un dibujo hecho por mi)

Just as Earth seems to be settling on agreements regarding several issues, the Celestial Empire of Mewni attacked the French capital of Paris in a bid of conquering the Earth soon after. The French military however has repelled them and at the same time, the Empire has provoked the North Atlantic Treaty Organization whose members agreed on the French in a counter-invasion of Mewni.

As like the beginning of the show, Star is sent to earth to train to use the royal magic wand. But she will not be the only princess sent to earth. Join Star, Marco and Amailia as they go on crazy adventures and face forces unlike any other. Originally a collaboration between me and crysky who is recovering in the hospital after an accident. Best wishes to him.

Han pasado 5 años desde que Star entrego la varita a Ecplisa y todo cambio, ¿Que fue lo que paso en todo este tiempo?, ¿por que no regresaron? el verdadero mal se hace presente y tendrán que buscar toda la ayuda posible para enfrentarlo si es que quieren salvar no solo mewni si no todas las dimensiones.

When you give up so much for someone you love, it's possible to question if it's all worth it sometimes. Once a chance is open, a darker Star Butterfly takes a distraught Marco into her world, offering him everything he ever wanted. But will he stay because of his dream finally becoming a reality?

Freeze Day AU! Star was slow in saving Marco from the time stream and now Marco is trapped in the past. While Star deals with an altered present. Can Marco survive? Can Star keep her country from tearing itself apart? Probably not, but it'll be fun to watch! Story idea from Wolvenstrom

"En su mundo solo es un rostro más en la multitud de los suyos, en otro no era respetado por sus habitantes y era considerado alguien indigno de estar allí, pero en este mundo es el enviado del cielo que empuñara la poderosa espada para acabar con el mal que lo azota y busca expandirse a otros" Son las palabras que escucha Marco al tener en sus manos la espada que buscaba

Marco Diaz came back to Mewni. He thought he had been ordained a knight. He thought his friend would be glad to see him. Instead, he found himself escorted to the washroom, to squire under Sir Lavabo, the Knight of the Wash. Now Marco must prove his worth and face the real Mewni, without the benefits of being the princess' best pal. What trials await the new Squire?

"I love you." Were the last words she had ever said after running away from him. These words and her disappearance left him heartbroken. Saddened by the emptiness of his heart, his life deteriorates. Little does he know a certain forger will give him a chance to turn back time.

For Marco, things had been complicated enough on Mewn, but after a strange temporal makes him responsible for six teens, he finds that things can always get more complicated. Can he survive long enough for them to get home? and how is he going to explain this to everyone? Read and find out. (Starco, Manna, Jarco, Higco, Heco, and Kellco)

Marco comes back after sixteen years but he seams different so what happens and why else he seem so close to hekapok. T for language.
