Ane ni Iwareru ga Mama ni Tokkun wo Shiteitara, Tondemonai Tsuyosa ni Natteita Otouto

Being scolded by my sister was nothing new, but when she started training me personally, everything changed. Before I knew it, I’d developed unbelievable strength—powers far beyond what any ordinary person could achieve. “For an adventurer, this level of skill should be standard,” she’d say casually, as if expecting me to keep up with her impossible standards.

This is the story of how my older sister—the strongest warrior in existence—shaped me into something extraordinary. Through brutal training sessions and relentless challenges, she pushed me beyond human limits. What began as simple sibling rivalry transformed into an otherworldly journey, with me following in her legendary footsteps.

Now, as we traverse unknown lands together, I realize her harsh methods were a gift. The battles we face would overwhelm most, but thanks to her, I stand unshaken. This fantasy adventure isn’t just about strength—it’s about the unbreakable bond between siblings and the incredible legacy she’s entrusted to me.
