Jupita is taken to the hospital and is likely to survive. Jupita’s older sister and rising songwriter Juria and her mentor Saimon meet the Detective Boys at the hospital. Just before being attacked by a mugger, Jupita called Juria to tell her he was in another town. The Detective Boys begin investigating why Jupita lied about coming to Beika City.
