Jakurai goes to Nagoya to look for clues about TBH and runs into Hifumi and Doppo. Hifumi is working at the Nagoya branch of the host club. When they hear that club patrons have info on TBH, Jakurai, Ichiro, Kuko, and the others go help out at the club.
So, I worked super hard and 
my sales went through the roof!
!لذلك عملت بجدّ وارتفعت مبيعاتي عاليًا
Also hab ich mich ganz dolle angestrengt
und den Umsatz angekurbelt!
Así que me esforcé mucho
y subí las ventas un montón.
Me lo he currado un montón,
¡he vendido muchísimo!
Du coup, je me suis donné à fond,
et les ventes ont explosé !
Então eu trabalhei superduro e
minhas vendas foram às alturas.
Так вот, я здорово постарался,
наша выручка выросла в разы!
