[Issei x Tiamat/Penemue/Rossweisse/Ophis] ¿Qué tanto cambiaria un mundo en donde lo sobrenatural existiera, y los Angeles se comportaran como Angeles, los Angeles Caídos se comportaran como Angeles Caídos, y los Demonios se comportaran como...Demonios?

What if things were taken differently? Rias knew that her chances of performing on the Rating Game is going to end horribly. She was not going to win, and even with Asia Argento and Issei Hyoudou joining in, the latter being a Red Dragon Emperor. And it came true. Riser Phenex, the third oldest child of the Phenex Family wanted Rias for herself. He wanted to use her for his own lust and wanted to keep her for himself. He overpowered her and defeated her entire peerage all the while torturing Issei who continued to stand in his way, he enjoyed the humiliation he was giving Issei. She did not wish for this to happen, she hated Riser more than anything else and anyone else. She did not want to be married to him and ruin her life. She had to do something about this. However, fate had other plans for her, and she was not going to marry Riser. This story was inspired by @THUNDERsnek's version of this ship which is Red Dragon Family.

la infancia de issei fue un infierno por culpa de sus hermanos ya que el no destacaba en nada excepto que sacaba buenas notas pero cuando dijeron que el no tenía sacred gear su vida solo empeoro ya que lo ven como un inútil y sufrió no sólo traiciones sino también rechazos pero no saben que están creando a un monstruo ya que issei comenzó a llevarse de odio y deseos de venganza contra los que lo hicieron sufrir, tanto así que poco después ese odio termino transformándolo en un ser Oscuro donde este a partir de ahora se llamaría "Dark Collector" Inspirado en "Issei el Nuevo Black Hat" de @ Luisdarth4236

Dicen que la venganza es un plato que se sirve frío y yo no podría estar más de acuerdo con eso, perdí a mi compañero que consideraba mi mejor amigo para que después las personas que más amaba y confiaba me traicionaran atacándome a tal punto donde terminaron dándome por muerto pero lo que no saben es que yo regresare para poder disfrutar mi dulce venganza Portada hecha por Movimiento Anarky

After being killed and then coldly abandoned by Rias Gremory for his lack of power, Issei Hyoudou discovers he is the reincarnation of Merlin, Abe no Seimei, and King Solomon. He spends three years in an accelerated dimension mastering their legendary magic, taming Ddraig as an independent familiar, and contracting the original 72 Demon Gods. Upon finding that Rias erased his parents' memories, Issei is adopted by the Hindu Trimurti, who bless him with divine authority. Now a Sovereign King, he establishes Kuoh Town as a protected "Sanctuary" and humbles the Three Factions, forcing them into a peace treaty enforced by his own absolute laws. After defeating the Hero Faction and sealing the apocalypse beast Trihexa in a small box, Issei chooses to live a quiet life as a student-unattached to any harem or faction-while a reformed Rias abdicates her title to protect his borders from the shadows as penance.

Issei responded with President is president causing Rias to cry, everyone berates him for this, for not understanding Rias's feelings, instead of Issei taking the insults head on, he snaps at them, for ignoring him, even comparing some of them to Raynare. He also leaves in fury, after snapping at them, running away from everything, he eventually heads to the same place where Raynare kills him, deeming him too dangerous to be left alive, but something happens, he falls into the ground, which was impossible, he then wakes up only to see that he seemed to be in a yellow walled office room, with fluorescent buzzing lights, and a carpet on what seemed to be moist Issei is taken to a place where nobody has ever gone to, at least not by their own free will, will Issei survive this unfamiliar world or will he perish and lose his sanity in this new world High School Dxd belongs to Ishibhumi Backrooms belongs to backrooms. wikidot and backrooms.fandom The above two are the main crossovers Other crossovers Included Rankings: #1 in dollface on 20/06/2022 #1 in Level on 22/06/2022 #1 in Naofumi on 16/07/2022 #1 in Ravel on 16/07/2022 #1 in Backrooms on 8/09/2022 #1 in despair on 17/09/2022 #1 in insanity on 8/10/2022
