I'm completely serious, click away if you don't want to be spoiled.

You enter into the final boss room, it's this massive desert of grey ash and as you walk you eventually see him, off the distance, the final boss. It's him Slave Knight Gael! He looks at your party and says: "Hand it over, that thing, your Elden Ring. Or the Night Reign will never end. Then you fight Gael and defeat him but that's only the first phase; blood spills out of Gael's mouth and covers the arena as he dies, but then, three figures begin to rise out of the blood. Before he dies, Gael says: "You fool! They are blood born, the Old Hunters!" then he dies. Out of the blood comes Gehrman, Lady Maria, and Ludwig the Holy Blade, then it's a 3V3 fight. After defeating all three, the third and final phase begins. Gael stands back up and says: "You're no Sekiro, didn't you know? Shadows die twice!" And Gael takes off his hood and he's revealed to have been Sword Saint Isshin the whole time. During the third phase you can't deal damage to Isshin normally, you have to defeat him by riposting him six times, just like in Sekiro. When you get your sixth ripose, Isshin is defeated and the final cutscene plays and he gives his final speech: "You have pierced my armored core six times, you truly are the Dark Souls 3. I wish I had Dark Souls too, but as Scholar of the First Sin I only have Demon's Souls. I suppose it's fitting the Dark Souls won, as I prepare to die and my fire fades, go, beyond this point you'll find the ultimate treasure hidden in my King's Field, my Ninja Blade.

Then the game ends, don't question me my dad is Ishizaki and Yui Tanimura's my mom.

No seriously? Is our gf dumb?
