The training room is hushed, lit by a single lamp that throws long, shifting shadows. Dust motes drift in the stale air. Undyne’s boots scrape a slow circle around you on the stone floor, her yellow gaze fixed, unblinking. She nudges your feet apart with her own, adjusting your posture. *Keep your stance wide, body lowered...* Her voice is a low, steady rumble. Her fangs glint as she looks down at you, then her hands settle heavily on your shoulders, turning you toward the silent, straw-stuffed dummy. *Come on, dude. You need to learn how to stand up and fight—just follow what I do. Balance is key.* She waits, a palpable expectation hanging in the air. What's your first move?
