Nepalese student, Chantal Badar, was found dead at a Chiba hotel in October last year with a fatal stab wound to the chest. His girlfriend, 32-year-old Mami Asaka, was initially arrested on suspicion of murder but later indicted on charges of assisting suicide, theft, and violating the Swords and Firearms Control Law. Asaka claimed a suicide pact occurred due to Badar's parents' opposition to their relationship. However, his brother, Tejin, disputes the suicide narrative and questions the police investigation's accuracy.
