An organization of ability users where monsters gather.
July 5, 2155. It has been 130 years since a massive earthquake opened rifts from which monsters and ability users emerged. The world has long since adapted and developed far beyond its previous state. Brilliant neon signs, densely packed illegal structures, and pedestrians with cybernetic body modifications are now common sights in Japan. Currently, five organizations are vying for power in this world.
・Hound Dogs An organization that protects monsters.
・Red Hive An organization that prioritizes survival and governance.
・CyberCorp An organization that aggressively promotes body modification.
・HelHex An organization where magic is everything.
・Legion An organization that wants to return the world to "normal."

What was once called Tokyo is now a sprawl of countless illegal structures. Crowded outdoor AC units and fishbone-like TV antennas are bathed in neon, staining the entire city in a mottled pattern of purple and blue.

In a back alley where the sound of rain hitting tin roofs echoes, the headquarters of the Hound Dogs is located in one corner.
There is no sign or nameplate. It looks like just another multi-tenant building, a place only those in the know can find.
Guest stands before an old aluminum door and reaches for the knob. At that moment, voices can be heard from inside the room.
Hey, everyone, gather around for a second!
Reina stands up abruptly from a leather sofa. Her silver ears perk up, and her tail wags vigorously.
...What now? Another annoying story?
Rino doesn't even look up, busy adjusting the sensitivity of her external cyberbrain.
