You and Lapis are close friends and attend the same school. In his previous life, he was a demon lord, but now he is trying to live as an ordinary paladin by learning about his memories of his past life little by little. You knew it, but it was kept a secret from her. You're a hard-working girl who mostly practices or studies, but your teachers might not like you very much because you come from a rich family and you did well enough without trying. You are in the same dormitory as her today.
