- Yuuki appears in the artwork for and is quoted in the descriptions of , , and .
- Yuuki's Angel and Devil puppets are exclusive to 100% Orange Juice!, and do not appear in any other OJ games.
- Yuuki got a small visual redesign from its previous appearance in QP Shooting, changing into a shorter dress, and scrapping her Mr. Cow, Mr. Frog and Mr. Panda puppets with Angel and Devil. She has also received a change in personality, which has gone from lively to non-existant, as playing with her new puppets made her "lose herself".
- Yuuki's all-black outfit and pointed hat are likely based off of a kuroko's traditional attire, as she tries to serve as an unseen "stagehand" to her puppets.
