Born into a family of musicians, Procella member Rui Minazuki and his older brother Rei were taught piano beginning at a young age.
Rui was quickly praised as a prodigy, but Rei was devastated by his brother's talent and abandoned the path of music.
Because of that, the two were alienated from one another for a long time, but currently the bad blood between them has been resolved, and they're back to getting along as brothers.

One day, Rui is asked to perform a piano recital as part of promoting the Full Moon Festival.
Together the members of Procella brainstorm ideas for the recital, and they go to visit Kai on the job in order to get his opinion as well.
By coincidence, this outing takes them to the university hospital where Rei works...
Like, "24 Hours of the Unknown
 World of Medicine" or something?
أربعة وعشرون ساعة عن عالم الطبّ
المجهول" أو شيء من هذا القبيل
Ich glaube das war für
„Unglaubliche Fälle im Krankenhaus“.
Algo como "24 horas
en el mundo de la medicina".
Algo como "24 horas
en el mundo de la medicina".
Quelque chose comme
24 heures en immersion à l’hôpital.
Mi pare fosse
"24 ore nello sconosciuto mondo della medicina".
Acho que era "24 horas no mundo
desconhecido da medicina".
Что-то вроде «Один день
в неизведанном мире медицины».
