Daisuke locks Takei up in the basement of the Kambe residence. Cho-san interrogates him to find out who the mastermind is behind all of this, but Takei is shook with fear and refuses to speak. Daisuke discovers that the reason why HEUSC is being uncooperative is related to his parents’ research. Kato goes through the documents that Cho-san gathered in his 19 years of investigating the case and finds an important photo.
They don't have Japanese saké here,
but I'm sure it's damn good booze.
لا يملكون الساكي الياباني هنا

Aquí no tienen sake japonés
pero esto debe estar bueno.
Pas de saké,

Qui non hanno sakè giapponese,

Eles não têm saquê japonês aqui,
mas estou certo que é uma boa bebida.
