Kurokami Haruto, a 16-year-old high school student, lives an ordinary life with his older sister Kurokami Satsuki—a beautiful, gentle nurse who’s… a little too devoted to her little brother.  

Haruto always dismissed rumors about "Awakened Ones"—people who suddenly gained supernatural powers—as nothing more than internet nonsense. Until one day, after fighting with scoundrels to defend a strange girl, he woke up to a system interface flashing before his eyes:  

> 《 SYSTEM: "Chosen of the Abyss" Activated 》

> • Main Skill:  [Moonlight Blade Manifestation] - Summon up to three spectral swords.

> • Main skill: [Abyssal Devour] – Absorbs energy from the moon, converting it into personal strengths.

> • Hidden Skill (Rare): [Yandere EXP Farm] – Whenever a yandere develops feelings for him, all main skills gain double experience.  

> • System Service: "Scanning for yanderes within 10 miles… Detected: 1 target:Kurokami Satsuki."

Haruto: "…What is this?! My onee-chan?!"

Ryouta was just heading out, minding his own business, when he saw them. Azame. And Haruto. Walking together. Not just walking, but, like, really close. Too close for comfort. His gut twisted into a knot, a sour, bitter feeling bubbling up. Not because he was, like, in love with Azame or anything sappy like that. Nah. This was different. This was pure, unadulterated annoyance.
