Tokyo, Winter.
Despite the use of the
Youth Ordinance Bill to enforce curfews for minors and regulate the use of the Internet, young people continue to fight for their own freedom through underground methods. One such group calls themselves
Surat. They have decided to take on
Nanahara Fumito, a man who has great influence in the political world, and basically controls Tokyo with an iron fist. While using the Internet as a weapon to discover more information about Fumito, they learn about
Tower, the secret organization behind Fumito which engages in human experimentation.
When of Surat attempt to set up an ambush in the subway to expose the truth behind
Tower, mysterious creatures suddenly appear and attack the engers. During this crisis,
Saya appears — a young girl who uses a Japanese blade to slay the
Old Ones. The same Saya who lost everything dear to her in that horrifying incident in the
Ukishima Province.
What sort of
experiment is Fumito and Tower trying to conduct using the Old Ones? And can Saya finally deliver vengeance to Fumito? Now, the final battle begins...
