Boku no Imouto wa Iki wo Shiteiru (Kari)

A boy expresses a desire to write a novel about killing people and claims to have completed one using a device that reads directly from his mind. The story features a main character resembling his younger sister, Yuki, who has white hair and behaves in a spoiled, affectionate manner. Initially, the narrative seems to lean toward a lighthearted romantic comedy, which disappoints him. He then wakes up to a blonde girl named Karin, who tells him a teacher is waiting for his novel. He questions whether the events were a dream.
