The Lilies (リリーズ,Rirīzu) are a trio of best friends. The group was named for their leader, Yuriko Asai who was named after the lily flower. They attended Eitoku Academy and were in the same class as Tsukushi Makino during high school. The girls were known for constantly antagonizing Tsukushi, though they occasionally sucked up to her.
The girls are regular antagonists in the 1996 anime, in which they are voiced by Yoshiko Shimizu (Yuriko), Sahori Kajikawa (Erika), and Nami Sato (Minako). Their appearance and personality are kept the same, though they appear slightly more often than they do in the manga. An example being when they attempt to befriend Tsukushi once they think she is dating Tsukasa, whereas they only try not to be rude to her in the manga. The girls bully Tsukushi off-and-on for the rest of the series. In the finale, they have moved on from her to a new target.
The girls are played by Nami Tamaki (Yuriko), Akiko Kimura (Minako), and Momoko Otaishi (Erika) in Hana Yori Dango: The Musical (2016). Unlike the manga, they do not appear to have a particular animosity towards Tsukushi. They, nevertheless, bully her with the rest of the school. The Lilies perform two songs, "Cut Down Tsukushi" and "Chance."
