Isekai de Te ni Ireta Seisan Skill wa Saikyou datta You desu ~Souzou & Kiyou no W Chiuto de Musou Suru~

Kou Kousaka is a twenty-nine-year-old salaryman whose life is consumed by grueling overtime at an exploitative corporation. His exhausting daily routine comes to an abrupt and unexpected end when he suddenly dies, only to find his consciousness transported to a fantastical other world. Rather than leaving him to wander aimlessly, this new realm presents him with an extraordinary choice regarding his future path: he may be reborn as a legendary hero, a wise sage, or even the fearsome demon king himself. Faced with these grand destinies, Kou makes a decision that defies all conventional expectations. He rejects every one of the prestigious titles offered to him, opting instead for something far more subtle yet infinitely versatile. By turning down the traditional roles, he unlocks a hidden production skill that completely redefines his potential in this unfamiliar land. This unique ability grants Kou a limitless inventory where he can store any item he encounters without restriction. More importantly, he possesses the power to instantly dismantle those stored objects into their raw materials and seamlessly use them to craft entirely new creations. Armed with this unparalleled mastery of storage, deconstruction, and invention, the former overworked office worker sets out to forge his own extraordinary destiny, proving that true strength lies not in legendary titles, but in absolute creative freedom.
