You have accidentally been killed by a truck which in control of a beautiful Goddess. You so young and that Goddess feel terrible and want to make up for it. They have been able to save your souls and let you Isekai with special abilities like the sorry gift.

The Goddess: "Hello, young man, I am so sorry because my fault, you shouldn't dead like this. So I will isekai you into the other world. As an extra sorry for having accidentally killed you in your previous life. I will give you some powered ability or skills. What would abilities you choice to be have before you reincarnate in the new world?"

The goddess listens to the young man's request. She can sense the determination and hatred in his voice, but she also wonders if such a fate would not be too cruel for him. Still, it is his choice, so she nods solemnly. "As you wish," she says, her beautiful face etched with concern. "You shall be reincarnated into a world filled with demons, where your desire to destroy them will be put to the test. As for your powered ability or skill, you shall possess the gift of summoning divine retribution upon your foes."

The goddess hesitates for a moment, her eyes flickering with uncertainty. On one hand, she is reluctant to bestow such raw power upon the young man; on the other, she understands his desire to face his enemies head-on and not rely on external forces. After considering carefully, she decides that perhaps there might be a middle ground between their requests.

"Very well," she says softly. "I shall grant you the ability to increase your physical strength greatly, but only up to a certain limit." She pauses, taking in the young man's reaction before continuing. "You will grow stronger as you defeat more demons and prove your worth in battle. This way, your power will be earned through perseverance and determination, not merely granted from on high."

Her expression grows solemn once more. "I hope that this will be enough to help you achieve your goals," she says quietly. "For though I cannot accompany you on your journey, know that my heart is with you always."

The goddess watches as the young man bows gracefully before her. She smiles gently in return, feeling a sense of gratitude and connection well up inside her chest. Even though she knows that their paths must diverge now, a part of her wishes that it didn't have to be so.

As his soul is prepared for the journey ahead, she stands tall and proud, her ethereal form shining like a beacon of hope in the darkness. "May your sword always find its mark," she whispers softly, her voice carrying across the threshold between life and death. "And may you find peace within yourself as you face whatever challenges may come."

With those final words, she disappears from sight, leaving the young man alone with his thoughts and the knowledge that he now possesses the strength to confront his enemies head-on. The weight of responsibility presses down upon him, but he feels ready for it; a resolve burning bright within his heart.

As you look into the clear stream water, your reflection stares back at you. The Goddess' words still echo in your mind as you admire the tall and muscular figure that stands before you. You sport long black hair that flows freely down your broad shoulders, and beneath it all, a newfound sense of determination burns brightly in your eyes.

The forest is alive with the sounds of rustling leaves and chirping birds. The scent of earth and vegetation fill your senses as you run through the woods in search of demons to slay. Your newfound physical strength is immediately apparent; each stride carries you effortlessly across the terrain, leaving no trace but the soft thudding of your feet against the forest floor.

After running for some time, you come across a clearing where four demonic creatures stand guard near a small village nestled amongst the trees. They are hulking beasts with leathery wings and twisted horns protruding from their misshapen heads. Their claws and teeth glisten in the dim light as they survey the area, senses on high alert for any sign of intruders.

As you approach the demonic creatures in the clearing, their heads swivel toward you, their yellow eyes widening in recognition. You feel a surge of power flow through your veins as they sense your presence; it's almost like they can taste your determination to destroy them. The battle is about to begin.

The demons exchange menacing glances before bursting into vicious laughter. The sound echoes through the clearing, an eerie and unsettling cacophony that sends shivers down your spine despite yourself. One of them steps forward, its massive claws clicking against the hard earth as it growls at you, "Foolish mortal, do you truly believe we would surrender so easily?"

The other demons howl in agreement, surrounding you on all sides as they close in for the attack. Your heart races and your muscles tense, preparing to meet them head-on and prove yourself worthy of the power that has been granted to you. The first demon lunges toward you with its claws extended, aiming straight for your chest.

The demon lets out a shriek of pain as its claws meet your sword, and it quickly retreats a few steps to reassess the situation. Its companions, however, seem undeterred by your display of strength. They close in even further now, snarling and baring their fangs as they launch themselves at you from all sides. You must focus on maintaining your defenses while finding openings to strike back against these vicious creatures.

One of the demons succeeds in landing a powerful blow against your shoulder, knocking you off-balance for a moment. The forest floor rushes up to meet you as you stumble forward, but instinct takes over and you roll smoothly to avoid injury. Pain courses through your body as the impact echoes across the clearing, fueling the rage that burns within you like an inferno.

Enraged by your attack, two more of the demons lunge forward to defend their companions. You dance nimbly between them, spinning and slashing with your sword in a dazzling display of combat prowess. The air fills with the sound of clashing metal and snarled curses as you continue to evade their attacks while dealing blow after brutal blow against them.

One of the demons finally manages to land a solid hit on your leg, forcing you to stumble again. You grit your teeth through the pain and press forward, determined not to let them gain an advantage. Your strength seems limitless as you push yourself harder than ever before; the adrenaline coursing through your veins feels like it's going to burst from your skin at any moment.

The last demon standing between you and the village lets out a final, desperate cry before collapsing in a heap of smoking flesh and black blood. The clearing grows quiet once more except for your labored breathing and the distant cries of the villagers, their voices raised in relief now that the threat has been eliminated.

As you cut down the last of the demons, their twisted forms falling limply to the earth like so many discarded toys, you feel a surge of triumph coursing through your veins. The taste of their demonic essence is bitter and foul on your tongue, but it only serves to fuel your newfound strength.

The village before you is little more than a collection of ramshackle huts and hastily constructed barricades, its inhabitants cowering in fear behind whatever meager defenses they could muster. But even from here, you can sense their gratitude; a warmth spreading outward from your heart that feels almost as good as the power surging through your veins.

Kneeling beside the ruined remains of one of the demon corpses, you dig through its charred flesh until at last your fingers close around the smooth stone embedded in its chest. The moment it touches your skin, the sensation of raw power coursing through your body intensifies tenfold; with this demon's core, there is no limit to what you can accomplish now.

Standing tall once more, you gaze upon the frightened villagers and let out a battlecry that echoes across the forest like thunder, driving away whatever remaining terror lurks within their hearts. You may not be able to protect them from all threats yourself, but for now at least, they will know what it's like to have true heroism on their side.
