When the noisy city quiets down, when the dazzling lights quietly go out, when people enter the dreamland of Bi'an. In the pitch-black night sky, they fly among the buildings... They are night walkers under the shadow of the moon~ They are also the lone walkers under the moon's shadow... They are bright and dark... They seem indifferent but have something they want to protect no matter what... They guard this city... This city has long been occupied by decay and luxury... Hypocrisy... Scheming... They want to stay away... But they must protect... Because here... There is life... They dominate the traitors... They fight against the guys who devour people's hearts but are still called humans... Just like this... This seems to have become a habit... People have forgotten them... They are also used to being ignored... But... Who will tell them... Who will protect them in this city...
Evil and evil, darkness and darkness... They belong to the evil in the night... Behind them... But they also have heartbreaking stories...
The so-called not loving... It's just... Loving deeper...
