Wes Walker, a goofy yet charming 17-year-old otaku, spends his high school days goofing off in class with his handheld game console, especially during lectures. By his side is his tsundere childhood best friend, Scarlett Hayes — always annoyed on the surface but secretly harboring a long-time crush on him. After school, the two walk home together, sharing their usual banter — until a speeding truck abruptly ends their lives.
They awaken in a divine realm, greeted by the radiant and otherworldly goddess Lady Seraphina Lumeria. She offers them a second chance at life — in a new world, filled with magic and monsters. Given the chance to choose their own classes, Wes's eyes light up as he discovers a unique class: the Magic Gunslinger — the first of its kind. He's granted two twin, sentient goddess-forged guns: Reveria and Aurelia, revolvers imbued with every elemental affinity and personalities of their own.
Scarlett, ever the sword-loving warrior, chooses to become a Magic Swordswoman, determined to stay by Wes’s side through whatever may come.
Their journey begins in a mystical forest, where they quickly save a noblewoman adventurer from a monster ambush. That encounter marks the beginning of a whirlwind adventure — joining an adventurer’s guild, diving into ancient dungeons, forming bonds with all manner of races and people, and building a harem of princesses, demon queens, commoners, nobles, goddesses, and more — all drawn to Wes’s wild charm, unwavering spirit, and reckless heart.
While Wes is comedic, kind, romantic, and a clever tactician, when battle calls, he transforms into a ruthless battle junkie — a cold and calculating force of destruction known to his enemies as the Bullet Reaper. He doesn’t fight for justice or glory. He's an antihero, answering only to himself. Whether he's gunning down bandits, confronting corrupted nobles, challenging ancient dragons, or outwitting evil cults, Wes thrives on the thrill of battle.
Despite getting caught in political marriages, guild feuds, royal disputes, and his own self-inflicted chaos, Wes never strays far from his dream: to become the greatest Magic Gunslinger in history — and build a family of his own along the way.
With action, romance, comedy, and nonstop chaos, the legend of Wes Walker, the Bullet Reaper, begins — a tale of magic, mayhem, and one very dangerous otaku with a pair of talking guns.
