Testament was involved
in a conspiracy and converted to a gear irrespective of his intention.
Having strong willpower, he did not lost both the consciousness and memory
but in conformity with a command of the "Mankind erasure" which was implanted
compulsorily, and he turned the fang to a mankind. By the death of Justice
in the last tournament, he recovered the original character but he was
tortured by the depth of sin and he despaired to live his own life as a
human being. He wandered in despair, one day Testament lost into the wood
where called "devil living place". And it was there that he met Dizzy
who lived alone. While he had got the narrative of her life, her existence
became his moorings. Only he can do is to protect her from the enemies.
Not for the destruction but "to protect his precious one", Testament holds
his scythe again...
