After a grueling battle, Haruyuki managed to defeat the Legend-class Enemy Archangel Metatron, meaning it's only a matter of time before the ISS kits that have been polluting the Accelerated World are destroyed as well. Everything is finally working out for once...until the Red King, Scarlet Rain, is kidnapped by two members of the Acceleration Research Society-Black Vise and Argon Array!
Now, to keep his promise to protect Niko, Haruyuki must hunt down Black Vise using the special boon he received from Metatron. Meanwhile, Kuroyukihime closes in on the real-world Tokyo Midtown Tower with Fuko, Utai, and Akira in the hopes that they can disconnect Niko from the portal there, but rescuing her isn't as simple as it seems...!
