Reo Kawamura is the love interest of Mai Sawaguchi from visual novel Sono Hanabira ni Kuchizuke wo and its OVA Sono Hanabira ni Kuchizuke wo: Anata to Koibito Tsunagi. She is voiced by Hana Anzu.
Reo is an antisocial tsundere during her first couple of months in school she didn't talk to anybody in her class until she met Mai. She is very uncomfortable talking to people and would rather spend time with Mai then do anything else. Reo is shown to be very possessive of Mai and gets jealous when Mai socializing with other students. Reo is also very aggressive (especially in the Reo and Mai diaries) and she will bite Mai if she does something to upset her and emit a scary aura if Mai seems to have fun someone else.
When engaging in sexual activities with Mai, Reo is usually the more submissive partner, receiving and reacting to Mai's affections, fingering, tribadism and cunnilingus. Reo is known for squirting her love juices all over Mai's face, whenever Mai uses her tongue to bring Reo's sensitive pussy to climax.
Reo is not smart with technology and called Mai when her TV wouldn’t work. Mai quickly found out that it wasn’t plugged. Reo even refused to get a cellphone, because she believe “it is an evil device that heralds the downfall of society”.
