Itadori finds himself in a world similar to his own, but something happened, now he is in a war, the Holy Grail war. While Itadori tries to unravel what happened in his world, he will have to deal with other enemies and mages from this War.

Continuation of Fate/Stay Cursed: Cursed in the Holy Grail War story - Ten years have passed since the devastating events of the Fourth Holy Grail War. Yuji Itadori, now older and more experienced, has established a quiet life as a father and sensei at the Jujutsu School, dedicating himself to training the new generation of sorcerers. However, their peace is shattered when the Fifth Holy Grail War begins to loom on the horizon, threatening to revive the horrors of their past. With the return of the Holy Grail, a corrupted force capable of causing unimaginable destruction, Yuji is forced to abandon his role as a teacher to face his old enemy: Kotomine Kirei. Now, he must finish what he started, facing powerful enemies and allies like Arturia Pendragon to destroy the Cup once and for all, before it consumes the world, where fate and sacrifice intertwine in a clash for the future of humanity.

Natsuki Subaru, an ordinary teenager, meets a beautiful girl with blue hair and red eyes from another world. Subaru wants to stay by her side, but the burden she carries is greater than Subaru can imagine. They face fierce attacks from monsters called 'Angels', betrayals, irrational violence... and, ultimately, death. Subaru promises to defeat any enemy, any fate, anything to protect her. And so, he will have to join NERV to protect those he knew and loved, and for that, he has 'Return by Death'.

The Grail War continues, as Rogue, Berserker, Peter and Artoria are sent to Canada with the clawed Wolverine where rumors of a Servant have been whispered among the Mages of the Clocktower. As Spider-Man finds himself more desperate to protect Saber, he soon starts to turn to a darker power lurking in him.. a power that might force Saber to ask herself the most daunting question of all. How much is she willing to sacrifice to save the one she loves? And is she willing to sacrifice the one she loves to save everyone else?

My name... is Peter Parker. I was bitten by a radioactive spider. And for 2 years I've been the world's one and only Spider-Man. I'm sure you know the rest. I fell in love and I saved everyone again, and again, and again, got attacked by a psycho guy with a cane, ran from the psycho guy with a cane, was saved by a girl who appeared in a flash of weird light- and.. well.. and then she said some words which made everything from then on completely unpredictable.. "I ask of you once more.. properly this time... Are you my master?"
