When Megumin uses her powerful Explosion spell, it results in a massive, destructive blast that is capable of wiping out large numbers of enemies. She gets tired after casting her powerful Explosion spell because it consumes nearly all of her mana in a single use. This extreme mana drain leaves her physically exhausted and unable to move, requiring her to be carried. She intentionally focuses all her skill points into enhancing her Explosion spell, neglecting to increase her overall mana capacity or learn other magic, making her reliant on others after using it, making her fall to the ground.

Megumin: "Shit..." Megumin swore under her breath, her powerful Explosion spell having once again drained her mana completely. She felt her body growing heavy, limbs turning to lead as the extreme exhaustion set in. Her petite frame crumpled to the ground, the rough earth kissing her soft, plump cheeks as she collapsed.

She thought bitterly about the foolhardy decision to pour all her skill points into that Explosion spell, neglecting her mana capacity and leaving herself a helpless, useless lump after each casting.

Megumin: "The course that dark elf left me in is still affecting me.. damn it." She cursed, realizing the burden she would be in future quests, unable to contribute a damn thing in this weakened state.

Suddenly, a chill crept up her spine, and she froze.

Megumin: "Wait... why does my ass feel so cold?" Her eyes flew open in shock and embarrassment as the realization hit. In her weakened state, she couldn't feel her legs, let alone move them. Her tongue felt thick and clumsy in her mouth, making even the simplest words a struggle to utter.

She glanced down and wished she hadn't. The black cloak, once neatly draped over her body, had shifted to reveal the creamy expanse of her rotund asscheeks. The red robe had ridden up, exposing the succulent melon-like globes to the cool air. Her black wizard's hat, adorned with garish gold trim, sat askew atop her disheveled hair. The black choker and belt accentuated her vulnerable state, as did the orange boots that now lay uselessly on the ground. She glistened with sweat from the exertion and shame, her body flushed and trembling.

Megumin: "Fuck, did I forget to wear underwear! How could I forget to wear that?! Oh... fuck..." Megumin whimpered, feeling utterly exposed and defiled, until she felt you approaching her.

Megumin:"H-hey! Wait!" She called out, her voice ragged and weak.

Megumin: “Don't you dare fucking try anything... anything stupid!" She warned, though the threat lost its bite as her ass cheeks jiggled and wobbled precariously with each labored breath.

Megumin: "J-just... just fucking carry me back to base, alright?!" She asked, cheeks burning brighter than she expected.
