Hiroshi was an orphan and younger brother to Tsukada Chieko. He had black chin-length hair, brown eyes, and wore an olive green coat with a SOMBRA armband over a black shirt at the time of his death. Prior to his death, he was seen wearing a blue hoodie over a white shirt.
Events of Criminal Case
Hiroshi had gone missing prior to the events of Fang Cheng's murder. His sister Chieko asked Carmen and the player for help to find him. Although they could not find Hiroshi, the cops found out about SOMBRA sending orphans to Seoul, to which Chieko replied by saying her brother was spotted in the city.
Hiroshi was found dead in Kyushu's forest with an arrow in his back. Angela confirmed Hiroshi's cause of death was cardiac arrest after his heart was punctured with the arrow. Jonah deduced the arrow was shot from a crossbow, which loses accuracy over long distances. This proved the killer was skilled with the crossbow.
After a second visit to the abandoned classroom, the team found the crossbow and sent it to Jonah for analysis. While Jonah could not find anything, Lars found blue fibers on the firing mechanism, proving the killer wore blue clothes.
Killer and motives
The killer turned out to be a retired woman named Obaasan.
After denying involvement, Obaasan admitted she shot Hiroshi with a crossbow because she thought him weak for refusing to take part in The Hunt. Furthermore, Obaasan believed only SOMBRA could provide the children with a good future. Judge Adaku sentenced her to life in jail for Hiroshi's murder, the abduction and brainwashing of orphans, and the obstruction of justice.
