Undyne "What do you mean "This place"? I should be asking what's wrong with YOU!."

Reima "I mean, why are you living underground?" he corrects her.

Undyne huffs, "We didn't choose to live here, the humans forced us underground and sealed the exit."

Reima "Why not just dig your way out then? Can't imagine it'd be all that difficult."

Undyne "We weren't buried. The humans sealed us inside with some kind of magic that prevents us from ever leaving... Unless a G.o.d breaks it."

...

Reima "A G.o.d?" he asks curiously.

Undyne nods, "A monster gets a HUGE power boost when they absorb a human soul, you'd need to give a monster 7 to make them a G.o.d... But with that human ma.s.sacring their way through the underground we had to use the 6 souls we'd already gathered."

Reima "How'd you manage to acquire souls? That kind of magic is incredibly rare." he asks, knowing full well how difficult it is to manipulate souls.

Undyne "I'm not the person to ask about this, but from what I've heard human souls linger around after death, allowing us to seal them until they need to be used."

Reima "And... How did you use the souls?"

Undyne "King Asgore decided that the only way we could prevent the human from destroying us all was to split the souls and have all monsters absorb a portion. "A united front will prevent our destruction." he says"

Reima "You feel any stronger after absorbing a human soul?" he asks.

She nods, "I feel like I could stop that human in their tracks!... But, I know everyone would be better off if we fought them together."

Reima ponders for a moment before retrieving a single human soul from his reserves, "Yo, Undyne?"

She turns and spots the white misty substance in his grasp, "What is that?"

Reima "This? It's a human soul obviously." he states.

Undyne shakes her head, "No, it looks completely different to the 6 we'd previously gathered."

...

Reima "Those 6 souls wouldn't happen to resemble a heart shape right?"

Undyne nods, "Yeah, how'd you know?"

...

Reima "I think the humans in this world and ours, are rather different. From what I've seen those heart-shaped souls are much, much more powerful than a regular human soul. How many monsters live down here?"

Undyne crosses her arms and thinks for a moment, eventually answering him, "Around 2000."

Reima "2000 monsters receiving the power of 6 equivalent to Lord Souls... To be honest I'm curious at the results." he mutters.

Undyne "Huh? You wanna fight?" she asks, taking his words as an offer.

Reima nods, "Sure, this area looks big enough... Show me how strong you are." he says as Priscilla and Nerissa back away to give them room.

Undyne puts her helmet back on and summons a blue spear into her hand, "Hah! You're going down punk!" she says as she throws it at him, leaving a trail in the air as it rockets towards him.

Reima grabs it out of the air and attempts to examine it, but it dissipates not long after. He then ducks a couple more spears thrown at him before waving his hand and creating a couple Crystal Soul Spears.

Undyne eyes them curiously but doesn't hesitate to strike those that get close to her, her spear whacks a couple out of the way before stabbing one of the Crystal spears point to point. The spear fractures and explodes as Undyne's spear dissipates forcing her backwards and making her tumble from the impact.

Reima "Is that all you got?" he asks the fish-monster-lady-thing with a grin.

Undyne gets up and shouts at him, "You've seen nothing yet!" and casts some kind of green magic at him. He lets it wrap around him but it doesn't seem to impede his movements, he wasn't sure if it did anything at all... That is, until a barrage of spears begin to home in on his position, he tries to slap one away but realises it's a soul attack. Not something he can physically block. Instead he casts a Protego, the s.h.i.+eld easily blocking the rest.

Undyne "HEY! That's cheating!"

Reima "Yeah? Your spears are cheating." he states with a smug smirk.

Undyne growls, "I'll show YOU!" she shouts and dashes towards him, attempting a stab at his stomach. He slaps the spear away with his hand and flick kicks her knee, causing her to stumble. Once her balance is unstable he performs a palm strike at her chest, knocking her onto her back with a *Thud*.

She doesn't seem quite done yet though, springing off of the floor while tossing a spear that is easily blocked. She summons another spear in her off-hand, using them both as makes.h.i.+ft rapiers and attempting to stab him with them.

He casts a relatively low-powered Aard which launches her away, he then conjures dark red flames that slither along the ground like snakes, surrounding, and trapping her.

Reima "Your strong, stronger than most human's I've met." she states as Undyne huffs and sweats from within his flaming trap.

Undyne "Your not bad yourself, but, I. WILL. NOT. LOSE!" she exclaims, tossing many spears in a flurry that are blocked by a quickly cast Protego. She continues this until she eventually collapses to the ground, breathing heavily and sweating profusely.

...

Reima "Er, you want some water?"

The fish girl nods and Reima retrieves a couple bottles of water from his Folded s.p.a.ce, dispelling the flaming trap and handing it to her.

Undyne huffs and downs the water before looking up at him, "I almost had ya!"

Reima shakes his head, "In your dreams. Any more and I'd have ended up with more sus.h.i.+ than I would know what to do with..." he jokes.
