Series by 遠藤達哉

Twilight, a master spy from Westalis, is tasked with his most challenging mission yet: to infiltrate an elite school and get close to a high-profile target. To do so, he must create a fake family in a week. Adopting the alias Loid Forger, he recruits Anya, a telepathic orphan who can read minds, and Yor, a skilled assassin posing as a civil servant, to play his wife. Unbeknownst to each other, they all harbor secrets, but their makeshift family dynamic begins to blur the lines between mission and genuine bonds. As they navigate espionage, school life, and domestic chaos, their unique skills and hidden identities create a mix of humor, action, and heart.
