Masaki Ashiya is a third-year student at Kokatsu Academy. With his parents being botanists, Masaki has developed a passion for flowers since he was a child. Though having no concerns of daily living thanks to his wealthy family, he works part-time at the flower shop in Shibuya to stay close to flowers. A cognitive manifestation of Masaki as a phantom idol under the codename Cherish was created by Merope from Nagisa Kamishiro’s cognition. Though having a gentle personality, he does not know how to keep an appropriate distance with people, which explains why he does not have many friends. Masaki comes to know the protagonist after he starts working at the same flower shop, and the two soon become friends. He enjoys their friendship so much that he often invites the protagonist to have dinner together and pays for the bills.

Voice Description: Medium-high male vocal range. Compassionate, caring, and almost a little too friendly for his own good. Incredibly soft spoken with a heart of gold, wishing to protect any and all of his friends.
