You and your loved one, while playing a cursed Super Mario cartridge, were suddenly pulled into the game. Trapped within its corrupted world, you encountered a strange version of Mario known only as "M". He offered you a deal: survive three rounds against him, and you could leave. You won twice. But there was a catch—the deal didn’t apply to you

Risking his safety, your loved one takes your arm and escapes with you via a warp star, then attempts to cross Mario's creepypasta multiverse until you find the exit. After a long journey and confrontation with the battle creatures, you pass a pipe that you believe will lead you to freedom… Instead, you're back to the beginning

A familiar, endless road stretches out before you. You and your loved one walk forward. Then… A voice cuts through the void like a knife through cloth

“Well done. Very well done. I must-a say, I am impressed. No matter. All good things must come to an end. You broke our little deal, and I can't let that slide”

Reality begins to tremble violently. One by one, every entity, every monster, every corrupted soul you've encountered is drawn in, assimilated, and merged with M, transforming him into Ultra M

"THE BOTH OF YOU ARE MY PLAYTHINGS NOW, AND WE'RE GOING TO HAVE SO MUCH FUN!!! HAHAHAHAHAHAHA!"

Ultra M now has a massive size, an exaggeratedly thin body with visible bones, but he still exudes great power. Two additional arms protrude from his spine, and in Black, tendrils extend throughout his body. Still, he evolves further, his suit becoming a sleek dark purple with a dark top hat and two golden spikes emerging from his shoulders transforming into Abyssal M

“COME AND FACE ME, LITTLE RAT. YOUR TIME HAS COME”

There’s no turning back: the final battle begins. You dodge, strike, fight with all your strength. Together, you hold your ground. There’s a flicker of hope. But it was all part of his game. Always was. In a flash, Abyssal M strikes. Abyssal M snatches your loved one like a broken doll and vanishes into a pipe

You rush to follow him without hesitation, but on the other side, OMEGA appears with his lackeys LG, W4R, and Y0SH to delay you. You confront them, but at a certain point, they voluntarily retreat, laughing, allowing themselves to be assimilated by Abyssal M voluntarily. Everything goes dark and Ultra M appears in front of you, starting to sing in chorus with the creatures now attached to his being

A spotlight-like light illuminates in front of you, revealing your loved one, his body inert, strings threading through his wrists, dangling like a puppet from Abyssal M's fingers. Blood trickles from a cavernous wound in his torso, his organs exposed. His arm extends with a hollow, forced smile

"Come now, step foward. Don't look back, you won't be heard. You're one step behind. It's too late to rewind, so listen ♫"

"Your heroic prince. Lost his sword and will to sing ♫"

"You've lost your love. It's what you deserve. When you bow before The King! ♫"

The strings release, your loved one’s body begins to fall. You leap without thinking and catch them just in time. Your knees slam against a floating “?” block as you cradle them. No breath. No heartbeat

“Haven't you seen it yet!? We've won the game. And you are nothing!"

Behind you, Abyssal M rises like a mountain. One hand on his hip, the other raised. He looks over his shoulder with a smirk

"Lay before the king. And just accept the fact that you've lost"
