The protagonist, a young man named Amano Suzune, finds himself reincarnated in a new world called Merunvara after a divine error caused his death. He decides to document his new life as a streamer, starting with a recap of his first three days.
His transmigration began with an encounter in a void-like space with a god who apologized profusely for mistakenly causing his death. The god explained that Suzune was killed because the god mistook his gamer shouts of "Hyahha! Kill all enemies!" for a genuine threat. Despite the god's apologies and the offer of reincarnation, Suzune's original body was destroyed, making a return impossible. As compensation, the god offered him a chance to be reborn in a world of swords and magic, complete with a "cheat item" and some innate advantages. Suzune, a fan of isekai stories and a devoted viewer of streaming videos, eagerly accepted. His primary request was for a world with swords and magic, elves, and dragons, though he rejected the idea of a king who would send unprepared adventurers to fight a demon lord.
Upon arriving in Merunvara, Suzune awoke in a forest. He discovered a blue backpack, a gift from the god, containing a tablet that could display streaming videos without needing to be charged, a knife, a bottle of water, and a note. He also noticed his appearance had changed dramatically; he was now a handsome young man with blonde hair, a stark contrast to his former self. After a brief period of existential confusion about his new identity, he accepted his altered appearance, reasoning that it might offer advantages.
His immediate priorities were securing food and water. He found a shallow cave to serve as a temporary shelter and, after a day of exploration, discovered a large, clear river. He refilled his water bottle and drank his fill, noting the convenience of the bottle provided by the god. He then set out to hunt for food, crafting a spear and a bow and arrows. The god's influence seemed to grant him an intuitive understanding of how to use these weapons effectively. He successfully hunted a rabbit, which he then cooked over a campfire he managed to start using friction, a skill he found surprisingly easy to master thanks to the god's subtle assistance.
As night fell, Suzune reflected on his situation. He had secured basic necessities and a shelter, but he realized he had forgotten something crucial: his beloved streaming videos. He had been so focused on survival that he hadn't had time for entertainment. He resolved to watch them the next morning.
The narrative then shifts to a flashback detailing Suzune's past. He recounts his lonely childhood and his brief period of friendship in middle school. This friendship ended abruptly when, during a playful moment, his friends accidentally broke a classroom window. Suzune, paralyzed by fear of punishment, abandoned his friends and fled, an act that deeply scarred him and led to the dissolution of their friendship. This experience instilled in him a profound sense of regret and a fear of inaction.
Returning to the present, Suzune, now in his new world and with his basic needs met, finally accesses the tablet. He is surprised to find only three videos available, titled "Day 1," "Day 2," and "Day 3," all featuring himself as the thumbnail. This discovery marks a significant turning point, suggesting that his streaming journey in Merunvara has already begun, and the god's influence extends beyond mere reincarnation.
