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.
Doc, I don't have much to 
offer, but I'll help you.
.ليس لديّ الكثير لأقدّمه، لكنّي سأساعد
Auch ich werde tun, was ich kann, Doktor.
Profesor, aunque no sirva de mucho,
también ayudaré.
No creo que pueda ser demasiado útil,
pero cuenta conmigo.
Je ne suis pas très utile,
mais je vous aiderai.
Doc!
Doutor, eu não tenho muito
a oferecer, mas vou ajudar.
Доктор, я помогу чем смогу.
