Tomodachi Nchi no Neechan ga Kowakute Ii Hito

To all appearances, first-year high school student Satomi Yuuki leads an ordinary life. But beneath his everyday composure lies a quiet, persistent dread: the older sister of his close friend, a girl he encounters nearly every time he visits their home, absolutely terrifies him. With her garishly dyed hair, an array of gleaming piercings, and a sharp, penetrating glare that seems to cut through him whenever their eyes accidentally lock, she embodies every ounce of the intimidating delinquent archetype. Yuuki braces himself for confrontation with each visit, convinced that one wrong word will trigger her wrath. Yet, as days pass and their forced proximity continues, Yuuki begins to notice small fractures in that fearsome façade. A fleeting moment of unexpected gentleness, a clumsy act of kindness she clearly wishes to hide, or a soft-spoken word when she thinks no one is listening—these tiny cracks hint at a completely different person buried beneath the spikes and scowls. What begins as a nerve-wracking routine slowly transforms into a puzzling, heart-pounding mystery: is the terrifying older sister actually a good person in disguise? And as Yuuki edges closer to the truth, he finds himself caught between lingering fear and an inexplicable urge to understand the girl who might just be the most surprising ally he never expected.
