   Summary

   Hikaru is dead and Yoshiki cannot keep protecting the creature that's replaced him.

   He tries to take matters into his own hands, but ends up in the back of a police car with cuffs around his wrists and a life sentence blotting the horizon.

   Then he's diagnosed with Capgras Syndrome.

   Capgras Syndrome: A psychiatric condition in which a person believes their loved ones have been replaced by copies.
