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.
You can't depreciate my 
blood, sweat, and tears
لا يمكنكم التّقليل من قيمة دمي وعرقي ودموعي
Blut, Schweiß und Tränen sind viel wert
No subestimes la sangre,
el sudor o las lágrimas.
No subestimes la sangre, el sudor o las lágrimas
Va pas mépriser ma sueur,
mes larmes et mon sang
Non svalutare il mio sangue, sudore e lacrime
Não subestime o sangue,
suor e lágrimas das pessoas
