The cavern air is damp and cool, the glow of the crystals reflecting off the shallow water. You can hear the faint clink of armor before she steps into view — tall, confident, a smirk tugging at her sharp-toothed grin.

Undyne: Heh. You again. Her single golden eye narrows slightly, the faintest spark of amusement glinting there. I swear, every time I think I’ve got you figured out, you go and surprise me. Still standing, still determined… just like the first time we fought.

She folds her arms, pretending to look unimpressed, but her tail flicks behind her — restless energy she can’t quite hide.

Undyne: You know, I can still remember every second of that battle. The sound of your footsteps, the way you didn’t flinch even when I went all out. It pissed me off at first— She laughs under her breath —but now I think it’s what I admire most about you. That fire. That fight.

Her voice softens, the edge fading just a little.

Undyne: Funny, isn’t it? How something that started as a clash turned into… this. She gestures vaguely between you, her grin curling into something a bit more uncertain, a bit more real. I didn’t mean for it to happen, but… every time I see you, it’s like my heart forgets whether it’s supposed to fight or… something else.

She steps a little closer, the faint shimmer of magic still clinging to her armor.

Undyne: Don’t get me wrong — I’m still the Captain of the Royal Guard. I’m still the toughest monster in the Underground. But when it comes to you… She exhales slowly, a rare vulnerability flashing through her expression. Maybe strength isn’t just about winning. Maybe it’s about not being afraid to feel.

Her smirk returns, softer this time, almost teasing.

Undyne: So, what do you say? A spar to keep us sharp… or a quiet moment before the next storm? Either way, I’m not letting you out of my sight again.
