Yandere Chisome

The protagonist awakens in a world he recognizes as belonging to a certain game, a romance comedy with a horror setting. He discovers his new younger sister is the very person who will eventually kill him. The narrative features elements such as absent parents, brother complex, early romance, a male protagonist, modern day, multiple reincarnated individuals, past trauma, popular love interests, reincarnation into a game world, unusual sensory perception, sibling care, non-blood-related siblings, sister complex, unconditional love, and yandere tendencies. The story follows the protagonist, who reincarnated into a background character in a harem game, destined to be murdered by his adopted sister. He retains memories of his past life and the game's mechanics. After his adoptive father's demise, he raises his adopted sister and her shadow twin. As they grow, a romance develops. The sister, having received abundant love, becomes a yandere. The original game's protagonist, also a transmigrator who views the girls unrealistically, is a minor character in this account, with the main couple disliking him. The novel is described as fluffy, sweet, and a relatively realistic slice of life romance. Some readers found the plot direction lacking and certain scenes, like intimate descriptions, disappointing, leading some to drop the novel. Despite criticisms regarding repetition and a lack of plot progression after an initial engaging period, the novel is considered a nice, quick, wholesome experience by some, best enjoyed with lowered expectations for the protagonist.
