Togetsu Rei[]
Esora and Rei met at a piano recital when they were in elementary school. Esora admires Rei and wishes she could be like her, and also loves her piano playing. Talking to Rei at that recital convinced Esora to quit piano and to find something that she could truly enjoy (that being Peaky P-key). They are old childhood friends and give each other birthday gifts every year.[1] Throughout game stories and card episodes, it is shown that Esora is very fond of Rei, and became unusually flustered when Rei's older sister said "Rei is really lucky to have a girl like you [Esora] around" and that she hopes Esora won't leave Rei's side. When Rei happily but innocently said they will stay together, Esora asked if Rei knew the true meaning behind those words.[2]
