It's time for the culture fair and everybody is having a great time! Everybody, that is, except Yamamoto.  Yushi wants to help her really badly, but...
my periods were so bad, I couldn't stand.
hatte ich so fett die Periode,
dass ich nicht mehr stehen konnte!
Ogni volta che avevo le mestruazioni
 non riuscivo a stare in piedi!
minha menstruação era terrível de não aguentar.
месячные такие были, 
даже встать не могла.
