In the midst of a desperate battle against the powerful Ascendant Vonnegut, Commandant Kiruka of the elite Gray Raven squad is suddenly thrown through a dimensional rift and into a completely different world - the war-torn Earth of Goddess of Victory: Nikke. Stranded in a reality where humanity hides underground in the Ark while fighting the mechanical invaders known as Raptures, Kiruka must adapt quickly. With no way back to his squad or his own dying world plagued by the far more insidious Punishing Virus, he is forced to cooperate with the Ark's forces. His overwhelming combat prowess - blending a reality-cutting crimson katana, dual energy pistols, collapsible energy bow, and advanced martial arts - quickly catches the attention of Commander Renji and the Counters squad. As Kiruka proves his worth on the battlefield, he begins forming bonds with the Nikkes, especially the strict yet easily flustered tsundere Privaty. However, the secrets of his world cannot stay hidden forever. When Kiruka finally reveals the horrifying truth about the Punishing Virus - a corruption that doesn't just destroy, but replaces and turns allies into monsters - the Ark's leadership, including the enigmatic Deputy Chief Anderson, is forced to confront a threat potentially far greater than the Raptures. Now, as Kiruka trains alongside multiple Nikke squads and clashes with the dangerous Heretic Modernia, two apocalyptic wars edge closer to colliding. With his Gray Raven squad still fighting without him back home, and the shadow of Vonnegut looming across dimensions, Kiruka must decide how far he will go to protect this new world... before the Punishing Virus finds a way to follow him. A crossover story of survival, trust, and war between two broken worlds. Will Kiruka's strength be enough to change the fate of both realities?

-To be Born a Keikain is to command power. -To be Bokue Keikain... is to rewrite the damn rulebook. -Bokue Keikain isn't your Average Exorcist. He's not even your Average anything. He's the wildcard in a world of Devils, Jujutsu Sorcerer, Angels, Curses, and power-obsessed clans. -With one foot in the occult, one hand holding a triple cheeseburger, and one ridiculously clingy nekomata who calls him "Darling," Bokue doesn't fight for justice or vengeance-he just wins. Always. -So when a Special-Grade Cursed object appears in Tokyo, everyone expects war. Instead, they get Bokue. -I mean.. He breaks the laws of Jujutsu Sorcery just to prove a point. -"Sealed object? Bro, I already broke it." -Welcome to Tokyo-where the Onmyōji plays by his own rules. --- 《•Current Mashup Worlds•》 [Highschool DXD] [Jujutsu Kaisen] [Nurarihyon no Mago] [Strike the Blood] [The Testament of Sister New Devil] And more...

Luffy with no Devil fruit but something better

After dying in his sleep, a modern-day anime fan isekai as a child, crewless Monkey D. Luffy. No crew. No Haki. No Gum-Gum fruit... yet. Just pain, awkward child limbs, and a system that turns life into a grindfest. Then the Partner System kicks in. To grow stronger, Luffy has to power up others first, because apparently being the main character wasn't hard enough. Each buffed-up partner boosts his own stats and unlocks powers from across the anime multiverse. Fairy Tail magic? A one-hit kill blade? A soul-cutting sword that speaks? Absolutely. Now armed with grindable friendship, hellish Garp training, and a suspiciously game-like UI, Luffy's ready to recruit his way to Pirate King. A dark, reimagined One Piece universe.

I am very death battle fan

Ren regains the memories of his past life, expecting to live a normal second chance in an ordinary world.

As a former player of the game, Ren can't help but feel thrilled. What fan wouldn't dream of becoming a trainer and guiding their favorite horse girl to victory? Determined, he sets his sights on that path. Unfortunately, Ren regained his memories far too early. None of the beloved characters he once knew have debuted yet, leaving him in unfamiliar territory.
