His gentle demeanor and empathetic nature make him a trusted companion, especially for Miyuki, whom he supports with unwavering loyalty.
One of the most memorable arcs involving Nagisa Kashiwagi comes during a well-intentioned (if slightly misguided) scheme to help Miyuki confess his feelings to Kaguya. In a bold move, Nagisa Kashiwagi agrees to pretend to be Miyuki’s girlfriend—a role he takes on not for personal gain, but purely to help his friend.
