After comforting Chara, you wiped out her tears and kept moving on. You took another umbrella and walked some more until it started raining, you were still thinking about that song, but your thoughts we're cut short by a voice

???: Yo, you got an umbrella?

You look and saw Monster Kid in a corner

Y/n: Umm.. Yeah...?

MK: Awesome!

Chara: Yay, the kid's back

He goes to your side under the umbrella

MK: Let's go!

You both started walking in silence until the kid broke it

MK: Man, Undyne is soooooo cool. She beats up bad guys and NEVER loses. If I was a human, I would wet my bed every night knowing she was gonna beat me up! Haha.

Chara: She lost to us before, so I think she'll lose again

You stayed quiet and kept walking with him until he stopped and spoke looking to an echo flower

MK: So, one time, we had a school project where we had to take care of a flower. The king -we had to call him 'Mr. Dreemurr- volunteered to donate his own flowers. He ended up coming to school and teaching the class about responsibility and stuff. That got me thinking... YO! How cool would it be if UNDYNE came to school!? She could beat up ALL the teachers!!

He went to your side again and both started walking.

MK: Ummm, maybe she wouldn't beat up the teachers... She's too cool to ever hurt an innocent person!

Chara: we'll see about that

You started walking again and you both saw the castle in the distance

You both walked away after looking at the castle, and you found another basket with some umbrellas, you decided to put the umbrella back at the basket but soon enough you found yourself in a dead-end

MK: Yo, this ledge is way too steep.. You, you wanna see Undyne, right...?

Y/n: Erm...

MK: Climb on my shoulders

You climbed on his shoulders and up the ledge

MK: Yo, you go on ahead.

Y/n: What about you?

MK: Don't worry about me. I always find a way to get through!

Chara: Are you prepared?

He runs away and falls right on his face again.

Y/n: Not at all, I dunno what's gonna happen

you continue on walking, after a minute, you found another sign

Y/n: "The humans, afraid of our power, declared war on us. They attacked suddenly, and without mercy... In the end, it could hardly be called a war. United, the humans were too powerful, and us monsters, too weak. Not a single soul was taken, and countless monsters were turned to dust..." Guess I know who the real monsters are...

Chara: Yeah, as humans, we are naturally bound to genocide

Walking a little more, you found two bridges, one on top of another, so you started crossing the bridge until a blue dot appeared in front of you, then another behind, and another to your side, and then you were surrounded by theses dots, and spears came out of them, you looked at the lower bridge and saw Undyne there, without a second thought, you started running in the bridge, almost getting hit by the spears, you kept running and running and the bridge started looking like a maze, you had to look down on the lower bridge to know the right path, as the spears got faster and faster, you were afraid that that could be your end... Until you reached a dead-end and the spears stopped, you looked behind you and there she was, looking straight to your eyes, you then heard the sound of her spears getting formed and soon after you heard a snap, your side of the bridge started falling down and you fell unconscious

???: It sounds like it came from over here... Oh! You've fallen down, haven't you...? Are you okay? Here, get up... Chara, huh? That's a nice name. My name is A...

Chara: Y/N! WAKE UP!!

You then shot your eyes open, you looked around and noticed you were in a golden flower bed, this time in a small river

Y/n: What was that...?

Chara: Thank God! I thought you were dead, you were out for a solid three minutes or so!

Y/n: Was I? Sorry

Chara: Don't scare me like that ever again

Y/n: Okay, I'm sorry...

You noticed you didn't have any scratch from the fall, but your legs hurt a bit, but you could bear with the pain. You got up and slowly walked out of where you had fallen, you saw so many garbage piles and noticed some of them were falling to the abyss below you, you didn't want to know what was waiting for you on the bottom of the abyss so you walked a little faster, you found more and more trash piles and a broken old bike, and right next to it, there was a practice dummy, you looked at it and let it be... Until it got mad

Dummy: Hahaha... Too intimidated to fight me, huh!? I am a ghost that lives inside a Dummy. My cousin used to live inside a Dummy, too. Until... YOU CAME ALONG

Y/n: Wait, what?

Dummy: when you talked to them, they thought they were in for a nice chat... But the things you SAID...!

Y/n: YO! I JUST GREETED HIM, HE WAS THE RUDE ONE!

Dummy: Horrible. Shocking! UNBELIEVABLE! It spooked them right out of their dummy! HUMAN! I'll scare your soul out of your body!

Mad Dummy blocks the way!

Y/n: Don't be stupid, man

Chara: do you really need to fight this guy?

He calls some dummies that launch their cotton in your direction, they literally miss you and hit the mad dummy

Dummy: OUCH! Watch where you're aiming for your magic attacks! HEY! you! Forget I said anything about magic!!!

Y/n: that's why he's in a dummy...

Chara: Y/n, I can't believe you are really fighting him

Y/n: I'm not, he's fighting himself

Dummy: I'll defeat you and take your soul!!

His dummies attack you again but hit him instead... You burst out laughing and the dummy gets even madder. It gets so mad that he fuses with his body completely, he stares at you and you keep laughing at his face so he leaves you and a ghost appears

???: Sorry, I interrupted you, didn't I?

Y/n: No dude hahahahaha

???: oh.. Okay... Wait... Aren't you the human from the ruins?

You stop laughing and looks at the ghost

???: Yes... You passed right through me that day... Sorry not to get out of your way...

Y/n: Eh? Sorry I didn't saw you...

Chara: was there a ghost there?

???: It's okay... I'm Napstablook by the way...

Y/n: I'm (Y/n)

Blook: Well... I'm going to head home now... Oh... Umm... Feel free to "come with" if you want... But no pressure... I understand if you're busy... It's fine... No worries... Just thought I'd offer...

He then flies away and you go on your journey, you found a weird-looking house next to an equal one but pink, on another entrance you found an angry fish-looking house

Y/n: Undyne...

Chara: You sure? Maybe it's the ghost's house

She says jokingly

Y/n: Or another fish person, Undyne can't be the only one

You slowly walked away from it and found a little entrance, you walked in and found an old turtle selling some items

???: Whoa There! I've got some neat junk for sale

Y/n: Actually... I wanna know about Undyne...

???: Undyne? Yeah, she's a local hero around here. Through grit and determination alone, she fought her way to the top of the royal guard. Actually, she just came through here asking about someone who looked just like you...

Y/n: Crap...

Chara: Did he said determination?

???: I'd watch your back, and buy some items... It might just save your hide! Wahaha

You left and started walking, suddenly a faint song was heard

Y/n: I guess he did... Monsters can't bare determination, can they?

You found another sign

Y/n: "Hurt, beaten, and fearful for our lives, we surrendered to the humans. Seven of their greatest magicians sealed us underground with a magic spell. Anything can enter through the seal, but only beings with a powerful soul can leave... There is only one way to reverse this spell. If a huge power, equivalent to seven humans souls, attacks the barrier, it will be destroyed... But this cursed place has no entrances or exits. There is no way a human could come here. We will remain trapped here forever."...

Chara: I guess not

You kept walking feeling a little down for the monsters, and you really regret what you've made before.

"Behind you" Was the only thing that the echo flower said in a very intimidating voice, you looked behind and there she was, the knight in heavy armor, looking at you with killing intent.

Undyne:... Seven. Seven human souls. With the power of seven human souls, our king... King Asgore Dreemurr... Will become a god. With that power, Asgore can finally shatter the barrier. He will finally take the surface back from humanity... And give them back the suffering pain that we have endured... Understand, human? This is your only chance at redemption. Give up your soul... Or I'll tear it from your body.

Y/n: Gruesome, ain't you?

She rushes in your direction with a spear in hand aiming for your heart, when suddenly...

???: Undyne! I'll help you fight!!!

Y/n: Hey MK, what's up?

MK: YO!!!! You did it!!! Undyne is RIGHT in front of you!!!

Y/n: I did it, bro, thanks for your help... Heh...

MK: You've got front row seats to her fight!!! Wait... Who's she fighting???

Undyne grabs the boy by his cheeks and drags him out

MK: Hey!! You ain't gonna tell my parents about this, are you?

After giggling about Monster kid complaining, you found another sign

Chara: Aren't you afraid?

Y/n: No, I'm terrified, but I can't run away now

Y/n: "However... There is a prophecy. The Angel... The one who has seen the surface... They will return. And the underground will go empty." Well... I'm in the right part now

Chara: What kind of empty?

Y/n: depends on which path we're taking I think?

You walked some more and found a bridge and...

MK: Yo! Yo, I know I'm not supposed to be here, but... I wanna ask you something.

Y/n: Yeah?

MK:... Man, I've never had to ask anyone this before... Umm... Yo... You're a human, right? Haha.

Y/n: Yes... I'm a human

MK: Man! I knew it! ... Well, I know it now, I mean... Undyne told me, um, "Stay away from that human." So, like, um... I guess we're enemies or something, right? But I kinda stink at that, haha.

Y/n: We don't have to be enemies, alright? But, I reckon you should obey Undyne for now

MK: Oh.. Alright then! Be seeing you, I'm gonna go home before my parents yell at me again

He runs off and trips, falling down on the bridge, only being held by his sweater!

MK: Yo! H...help! I tripped!

You run to help him and see Undyne doing the same, but when she sees you, she stops and let you help the kid

MK: Y... Y... Yo... Dude... If... If you wanna hurt my friend... You're gonna have to go through me, first

The kid said looking at Undyne

Y/n & Chara: What...?

Undyne steps back and vanishes in the darkness

MK: She's gone... Yo, you really saved my skin

Y/n: Don't worry kiddo, now go back to your parents, I bet they're worried sick

MK: You're right, thanks! I'll see you later

He walks off and you continue your path until you saw a shining armor on top of a hill

Undyne: Seven. Seven humans souls, and King Asgore will become a god.

Y/n: You've told me this before...

Undyne: Six. That's how many we have collected this far. Understand?

Y/n: Yes, Undyne, you have to kill me so you guys will see the light of day again... I understand this

Undyne: Through your seven and final soul, this world will be transformed... First, however, as is customary for those who make it this far... I shall tell you, the tragic tale, of our people. It all started, long ago...

Chara: Come on, really? History class?

Y/n: You don't have to do this, you don't want to do this, you just wanna kill me, right?

Undyne: You're right, WHY SHOULD I TELL YOU THIS STORY, WHEN YOU'RE ABOUT TO DIE?!?

She takes off her helmet and looks at your eyes

Y/n: Cute and scary

Undyne blushed and Chara looks a little mad

Undyne: Stop flirting!

You laugh a little and then you were hit by Chara who's a little upset

Y/n: Sorry...?

Undyne: You! You're standing in the way of everybody hopes and dreams! Alphys' history books made me think humans were cool... With their giant robots and flowery swordswomen.

Y/n: What?

Undyne: But you?

She looks at you again

Undyne: you are pathetic. Let's just Fight! Your life is all that stands between us and our freedom!

Y/n: JUST ATTACK ME FOR GOD'S SAKE!

Chara: Are you that eager to die? Dumbass!

Undyne looks a little upset, but happy that you want to go straight to the point

The wind is howling... You are filled with... Determination

Undyne starts attacking you

Undyne: EN GUARDE!

Your soul starts glowing green and you feel stuck, but you used a piece of Undyne's spear to defend yourself from her own spears, you feel like you're not going to die today... She throws spears from every direction just to hit you, but you slap every spear with your own, not getting hit

Undyne: Not bad, human

Chara: How do you...?

She starts throwing even more spears faster and faster, you're still stuck, but you feel like nothing could stop you. You hit every spear and grabs one just to throw back at her, hitting her hand making her smile a little

Undyne: I guess you can Fight!

She seems like she's having fun, so her spears get a little faster, but you're no longer green so you jump from her spears and grabs another one and hitting her again

Y/n: I thought you wanted to kill me, are you just gonna play?

Undyne: I can tell you the same thing!

Chara: Y/n... What the fuck is wrong with you? You were shaking your boots a minute ago

Undyne laughs while throwing her spears at you but they're yellow this time and hit you from the other direction, almost getting cut by them, you've gained a little more space to dodge since you shot a spear at her making her jump back a little

Y/n: C'mon Undyne, at least pretend you wanna kill me

You tease her which makes she smile angrily and throw more spears, you feel cornered, but you swing your spear making hers fly away from you, you then noticed an opening and punched her in the face making her hit you back

Undyne: You can fight, guess I can stop warming up

She throws at least 18 spears at the same time, you tried to dodge them all, but one cut you left arm and started bleeding, seeing this, you felt more determined and ran in her direction which startled her a bit, you punched her in the face and she kicked you launching you back and making you almost fall into a river

Chara: Y/n! Don't try to kill yourself!

She throws a spear at you with force

Undyne: I can't be having fun! You have to die!

Y/n: Crap...

You try to escape from her spears but one entered your same injured arm making you growl in pain but you kept holding on and threw a stone in her injured eye... She looks mad

Undyne: You have to die so we can see the light of the sun again! Face your fate human! You're gonna die by this hero's spear!

She threw spears at you with full force and you were able to dodge them all and cut her cheek with your spear

Undyne: Alphys told me that humans were determined... I see now what she means by that

She charges at you but you hit her with your spear cutting a piece of her armor out

Undyne: But I'm determined too

She throws more spears at you and you hit one spear with all your might making the spear pierce through her armor and making her bleed a little

Chara: Yes! Keep going! You can do this!

=================================

That sounded dirty

=================================

Undyne: You little brat!

She yells at you as she throws even more spears, but can't make any of them to actually hurt you

Undyne: I'll end this RIGHT NOW!!!

Your phone rings again and Undyne stops. You pick up your phone

Y/n: Yellow?

Chara: Are you... Why isn't she fighting you now?

Papyrus: Hey! What's up!?

Y/n: Hey Paps! Not much, you?

Papyrus: I was just thinking... You, me, and Undyne should all hang out sometime!

Y/n: That's a Great Idea Paps, I'm excited to meet Undyne, seems like you look up to her

Papyrus: I think you would make great pals! Let's meet up at her house later!

Y/n: I guess that's fine then, Talk to you later Bro!

He hangs up

Undyne: Are you done?

Y/n: Yes

Chara: WHAT?!

She throws a spear at you again but she misses, you then jump at her and you both rustle on the ground until you noticed that you were on a different area, a hot area, burning hot and you notice she's sweating a lot

Y/n: You ok?

She tries to hit you but she's tired and sweating, so you run away and she tries to run in your direction, you both cross a bridge that is above a lava river.

Undyne: Armor... So... Hot...

Y/n: Girl, you alright?

Undyne: But I can't... Give up...

She then succumbs to the heat and falls to the ground, you got scared and looked around to see what could help her until you found a water cooler and threw water at her. She gets up, looks at you, and takes a step back

Undyne:... Thanks...

She walks away but purposely drops some bandages on the ground pretending she didn't notice

Y/n: Anytime...? Heh

You said so she could hear but she rushes back home. You then pick up the bandages and started to apply them yourself, until you saw Sans

Chara: Is that it? Oh, wait, your arm e really messed up...

Y/n: Dude... Little help here?

Sans: sure thing pal...

He then starts to treat your wound applying the bandages and helping you heal them with Chara trying to help too

Sans: guess you've met Undyne huh?

Y/n: Yeah... I did

Sans: what do you think of her?

Chara: They literally almost killed each other

Y/n: Guess I find out when we hang out with Paps, but, that was actually scary

=================================

A/n: You fought Undyne and Chara seems like she's kinda interested in you, I wonder why
