Three days go by. You're still staying with your grandfather. But you keep getting a visit from the Devil. He'll be telling you stuff like, "Surrender yourself to me, (Y/N)." or "Be mine, (Y/N)." or "I get you to myself or all of Inkwell Isle suffers my wrath..." And so on. You couldn't say anything at the moment. Your granddad will always shield you and tell him to buzz off or leave you be.

It didn't work though. You went walking into the city earlier and you saw a wasp man looking like he was depressed. You asked what was wrong and he said this, "Uuuhh... ugh... D-devil... took my soul." He collapsed and you gasped and ran to get help.

Even the lights in the hospital went out of control and the patients were going crazy. You ran back to your grandfather and he said this, "Don't go into the city, (Y/N). It's too dangerous. The Devil's got them all doomed." 

You're up in your room and you're sitting on your bed. You look towards the window and you sigh. You hear the Devil's voice saying, "Give in, (Y/N). Be mine and mine alone.~" You yell, "Leave me alone, dammit!!" 

He chuckles and says, "Never!" You groan and you lay back saying, "Bastard." You hear him saying, "I won't stop my chaos until you give in to me, (Y/N) (L/N). Be mine or they suffer even more. Why don't you go and give your dear friend Marcy Stageplay a visit, huh? The great-granddaughter of a former runaway debtor of mine." 

You sit up and you say, "Come again?" You hear him saying, "Go ahead, sweetheart. See for yourself." You get up and you run out of there. You run downstairs and your grandpa sees you. He says, "(Y/N)? What's wrong, honey?" 

You say, "I gotta get to Marcy!" You run out of the house and Cuphead gets up saying, "Oh god. What happened?... Devil! You better not have had anything to do with it!" He hears chuckling from the Devil and the Devil says, "I'll save the best for last, old man. You." Cuphead squints his eyes.

You drive into island 3 and you get to your apartment building. You park outside and you get out of your car. You run inside and you get up to your apartment. You frantically knock and you yell, "Marcy!... Marcy?!" No answer. You say, "Oh shit!" You grip the doorknob and you open the door. You run in and you gasp.

There's Marcy. She looks like she's under control like a puppet. Her eyes are pure white and she looks to be floating. So does her new boyfriend Simon. You say, "Holy shit!! Marcy!" You back away and you say, "Devil! What the hell?!!" You hear laughter from the demonic ruler himself and you see him appear. You gasp.

He grins and says, "You see? There's going to be a lot worse with others... including your granddaddy and your great-uncle." You say, "Please... don't." He says, "Give yourself to me, (Y/N). Be mine. My woman. My desire more than anything else in this universe... is to have YOU as my wife. Give in... or give others' souls to me. Your choice, baby... You have four days. Four days... and all of Inkwell Isle will be wiped out, leaving just you. I don't want to have to sacrifice YOU. Not the woman I'm in love with. You are mine, (Y/N).~" 

You run out of there and you run down the stairs. You get to your car and you get in. You start it and you drive out of there. You drive back to island 1 and you get to your grandpa's house. You get out of your car and you run to the house yelling, "Granddad!!" You see the door opening and there he is. You get to him and he holds you close.

You hug him and you sob. He sighs and he says, "He got to her, didn't he?" You sigh and you say, "He'll stop at nothing. I know it." You sniffle. He says, "My god. And I thought I had to deal with my fate back in the day. This devastates me even more. My own grandchild." He holds you close. You say, "Poor Marcy." You sob and you say, "He got to her and Simon Carnation!" 

Cuphead says, "Ah, shit." He comforts you. You suddenly see the sky turn red and you gasp. You and your grandpa separate and you see this for yourselves. Cuphead says, "Devil!! Give it up, already!! You're not takin' my granddaughter!" You sigh and you look away. You knew what needed to be done. You knew the Devil would stop at nothing until he got what he wanted.

You suddenly see him appear and you gasp. The Devil is right there and he grins. You sigh and you grip your right arm with your left hand. You look away. You're thinking things over. You knew he'd stop at nothing until he had you.

Cuphead says, "Devil. Give it up. She ain't goin' with ya." Devil grins and says, "Suit yourself, old man." He brings his hand up and this causes Cuphead to be lifted from the ground. He gasps as he feels his throat being clinched. You gasp and you say, "No! Granddad!!" 

You look at the Devil. He says, "Me... or everyone's lives in Inkwell Isle is at major risk. Especially your granddaddy who's been taking care of you for most of your life while your WONDERFUL mother was locked away in prison. Up to you, sweetie.~" He chuckles.

You sigh and you look at him. You suddenly say this, "I'll go with you." Devil looks at you. Cuphead, despite struggling to breathe, looks over at you. He says, "H-honey. No." You say, "Granddad. I'm sorry. I can't let him take your life!" 

You look at the Devil and you say, "Put him down. Please? I'll go with you. I'll be yours. Just please... Leave everyone else alone. If it means saving them, I'll go with you." Cuphead strugglingly says, "N-no. Sweetheart." 

You say, "Devil... I'll be yours. Just leave everyone else be." He grins and he says, "Wise choice, my dear.~" He snaps his fingers and he drops Cuphead to the ground, letting him go. This makes the sky turn back to its blue color with white clouds. 

The citizens are back to normal. That one wasp man isn't suffering, now. The patients in the hospital are slightly alright, despite some of them nearing death, anyways. Even your best friend Marcy is fine now. And her new boyfriend, Simon Carnation. 

The elderly people in the nursing home like Cagney Carnation who is Simon's grandfather, Cala Maria... Yes. She managed to fit in there with being giant. Baroness Von Bon Bon. A friend of yours named Brittney Lowes is Baroness' granddaughter, Hilda Berg, Blind Specter, Ribby and Croakes, Djimmi, etc. They're all good, now.

Brineybeard was actually married to Cala, but he sadly passed away a decade ago. His and Cala's great-grandson Joey Brineybeard is your age and went to school with you. Werner Werman passed away last year. His grandson is two years older than you are. Leopold Werman. He like Werner was raised to speak both English and German, so he has the accent just like his grandfather did. 

(Season two of The Cuphead Show isn't currently out at the moment, so I don't know yet.)

You approach the Devil. He smirks and he pulls you close. He looks at Cuphead and he says, "Be lucky I was going to spare your gorgeous granddaughter, anyways. But the rest of you would've suffered or died if she didn't just now give in. She's mine now. However... She may say her goodbyes." You look at him.

He says, "Go ahead. Go tell your grandfather goodbye. Well..." He chuckles and says, "You can visit, but you'll be back with me afterwards. Remember, baby..." He strokes your chin and says, "You're mine or everyone in Inkwell Isle suffers from my wrath. I want what I came for and what I want is you, (Y/N) (L/N). I've fallen madly in love with you to the point where I'll cause pain and suffering upon the citizens of Inkwell Isle if I don't have you to myself. This is a much bigger deal for me than trying to take your grandpa's soul years ago." 

You run to your grandpa and he hugs you close. You hug him back and you say, "Granddad. I'll be okay. I just want you and everyone else to be. I love you so much." He sighs and he says, "You're brave, honey. But my god... I... I can't get over this. My own grandbaby givin' herself up like this so willingly. You're brave, honey." 

He sighs and says, "You really are like I am with dealin' with the Devil, himself. Difference is... he wants to deal with you a different way." You say, "He wants me as his wife, granddad. I figured that out." Devil grins and says, "And you're right.~" 

You pull away and you look at your grandpa saying, "I want all of you to live correctly. Go about your days, normally. Never suffer. I love you, granddad." He has a sad look on his face and he says, "I love you too, honey. I always will." 

He hugs you and you hug him back. You pull away and you lean in and kiss him on the forehead. You say, "I'll be alright. You and everyone else will be, as well. Tell uncle Mugs I've made my choice. You're all safe, now." He sighs and he says, "My little girl." Tears are in his eyes and he says, "I love you so much. My grandbaby." You say, "It's gonna be alright. Tell Marcy and the others it'll be fine." 

After all of that, you sigh and you walk to the Devil. He grins and says, "You've made a wise decision, my dear. Now... you're mine. My wife to be. Most beautiful thing I've seen here in Inkwell Isle. And now I've got you. And much to your luck... All of Inkwell Isle including the ones you love are safe, now." 

He holds you close and looks at Cuphead saying, "You owe nothing else to me, Cup. I got what I've wanted since I saw it. Her. YOUR granddaughter, nonetheless. So long, old man." He vanishes, taking you with him. 

Cuphead drops to his knees and he says, "D-dammit. Not my granddaughter. My little girl." He puts his hands up to his face and tears form in his eyes. He says, "M-my grandbaby." He sniffles and he says, "I love you so much, little sweetheart." He sobs.
