The day before the live show where Project Himmel's new unit "LUNA ω rabbits" are revealed, Mei gets a slight fever and has to stay in bed.
Worried about her, Satori and Rinne take turns visiting and talk about a side of Rie that Mei didn't know yet.
Having been together with Rie since her childhood, hearing this warms Mei's heart.
If I don't have one every day, 
it messes me up!
!إن لم أشرب واحدا يوميا فسيؤثر عليّ ذلك
Wenn ich’s nicht jeden Tag trinke,
geht’s mir schlecht!
Si no lo bebo todos los días,
todo me sale mal.
Si no lo bebo todos los días,
todo me sale mal.
Si je n’en prends pas un par jour,
je me sens mal !
Se non ne consumo uno al giorno,
mi sento scombussolata!
Se não bebo todo dia, fico toda zoada!
Если не выпью, весь день 
всё из рук валится!
