Throughout his existence, Yuuya Tenjou has been met with scorn and disdain from everyone around him, including his own parents. To compound the misery, his grandfather—the sole figure who ever expressed love—passes away abruptly, leaving Yuuya utterly isolated.
Even amid relentless hardships, Yuuya strives to extend compassion to those in need—yet even the kindest souls can endure only so much mistreatment. When he teeters on the brink of collapse, a sliver of optimism surfaces in the guise of a concealed door within his bathroom.
That portal grants passage both ways to an abandoned dwelling in another realm, where he immediately acquires game‑style attributes and abilities. Additionally, the house once belonged to a wise master, bestowing Yuuya with extraordinary weapons, gear, and crops that yield remarkable effects. With these newfound gifts, the formerly despised Yuuya could finally unlock his true potential and become unstoppable.
