Isekai de Cheat Skill wo Te ni Shita Ore wa, Genjitsu Sekai wo mo Musou Suru

In Isekai de Cheat Skill wo Te ni Shita Ore wa, Genjitsu Sekai wo mo Musou Suru, Yuuya Tenjou has spent his life as the target of resentment and contempt from nearly everyone around him, including his own parents. His grandfather is the only person who ever showed him affection, and when the old man suddenly dies, Yuuya is left completely alone. After moving into his late grandfather's home, he still does what he can to offer kindness to people who need it, but even his patience has limits as years of abuse push him toward a breaking point. That changes when a hidden door in his bathroom opens onto an abandoned house in another world and gives him two-way access between worlds. There, Yuuya instantly gains game-like stats and skills, while the house—once owned by a sage—contains remarkable weapons, equipment, and crops with extraordinary effects. Armed with these blessings, the boy who was treated as undesirable on Earth begins to transform his life in both realities, using his newfound power to reach the potential he never had the chance to show.
