While Nezuko basked in the power of the sun, a profound mutation took over her form, bringing tears to the spectators' eyes as the youngest of the Kamado siblings began to grow in size. Her stature increased, reaching one meter eighty, then two, then two and a half meters, with no sign of stopping.

Witnessing her unprecedented growth, the spectators scattered in fear as Nezuko's feet advanced like an avalanche, destroying everything in their path. Meanwhile, Nezuko herself teetered on the brink of consciousness, intoxicated by a potent mix of pleasure, curiosity, and oni malice.

When her ascension culminated, Nezuko reached over 30 meters in height, her colossal form casting a shadow that loomed over the valley, eclipsing nearby mountains and forests.

"Hm...", she murmured, still dazed and struggling to articulate her thoughts, seeking solace in her smaller form for guidance.
