Masato Tsuge is a supporting character in the anime Cherry Magic! Thirty Years of Virginity Can Make You a Wizard?!. He is a romance novelist who works from home and is one of the few close friends Kiyoshi Adachi has kept since their university days. Tsuge has a calm and thoughtful demeanor, but he is also awkward, quiet, and somewhat clumsy. When nervous, he tends to stutter. Despite this reserved exterior, he can be very straightforward when the situation calls for it. He is often relied upon by Adachi for levelheaded advice, especially regarding romantic matters, even though Tsuge himself has limited experience with love.

Like Adachi, Tsuge turns thirty as a virgin and gains the magical ability to read the thoughts of anyone he touches. He initially feels confused and unsettled by this power, which parallels the main protagonist's experience. Tsuge lives with a cat named Udon, whom he rescued from abandonment. His quiet life changes when he meets Minato Wataya, a deliveryman who regularly brings packages to his home. Tsuge begins to notice his heartbeat quickening whenever Minato is around, leading him to question his own feelings for the first time.

Throughout the story, Tsuge undergoes personal growth as he learns to confront his emotions and embrace the possibility of a romantic relationship. His relationship with Minato develops gradually, with Tsuge becoming more open and supportive, especially as Minato pursues his dream of becoming a professional dancer. Tsuge's ability to read minds occasionally plays a role in his romantic arc, helping him better understand Minato's true feelings. His role in the series is to serve as a counterpart to Adachi, exploring a similar magical predicament through a different personality and life situation, and ultimately finding his own path toward love and self-acceptance.
