Six months have passed since Tenku's visit to Lake Motosu and Japan is already in late autumn. After Shigeru's death, Tokyo was in an uproar because one of the leading company owners in the area was found dead in his office. The news quickly spread throughout Japan and even abroad.
The police and the Realizer have teamed up to find out who was behind Shigeru's murder, but they have found no clues. They only knew that a great sniper had killed him from one of the multi-story buildings near Yamanaka tower and most likely was a Relizer. They concluded from the holes in the bulletproof glass of the windows in Shigeru's office and the wound on his head.
Because of that, the three Realizer organizations in Japan called members who possessed Phantasmal Objects in sniper form and interrogated them. Sadly, none of them was found guilty. So they suspected that the culprit was an illegal Realizer from a terrorist organization.
