Thanks to Shu and Kisara's efforts, the Anti-Demon Bureau successfully detained Sharon, and peace returned anew to Bayron City. With his companions Mikami and Miles, Shu once again pursues the truth behind the continuous D Hazards that have been manipulated by some entity's volition. They continue compiling deductions to pin down the identity of the "True Agent," who they presume is lurking behind Junya Hanamura, the murdered Demon Agent. At the pinnacle of their deductions, Mikami reaches a certain conclusion and tries to contact Shu in a hurry...
I have to clear Mr. Mikami's regrets.
I can't leave it in someone else's hands.

Voy a vengar a Mikami.
No lo dejaré en manos de otros.
Voy a vengar a Mikami.
No lo dejaré en manos de otros.
Je veux venger Mikami à tout prix.
Devo finire ciò che Mikami ha iniziato. 
Non posso lasciare che se ne occupi qualcun altro.
Quero terminar o que o sr. Mikami começou.
Não posso largar nas mãos dos outros.
Мы обязаны отомстить за Миками.
