Lilysa Amano

She attends the same school as Okumura and is a female student one year junior to him. She first appears as a first-year high school student and is a cosplayer of Liliel. Her goal is to create a ROM of her Liliel cosplay. She doesn't use a pseudonym for cosplay and isn't active on social media, so she is known as Liliel in the cosplay community. She also loves adult-oriented content.

Initially, her feelings for Okumura were purely of friendship and respect as fellow otaku, but later she realizes that she truly loves him. She confesses to Okumura before a location shoot with Erika Awayuki, which she attends to achieve her goal of creating the "ultimate ROM."
