About

VALENTIS


VALENTIS GROUP, a massive corporation with branches all over the world.

Involved in every field imaginable—finance, trade, logistics, real estate, security—there is hardly anyone who hasn't heard the name.

—However, that is merely the public face.

Behind the scenes, it operates in the shadows as VALENTIS, an organization with vast funding, information networks, and formidable military power.


The headquarters is a massive skyscraper.

It contains every facility necessary for the organization, from administrative offices for rank-and-file members to training facilities, medical/measurement labs, intelligence departments, and executive-only zones.

Note: This plot is not linked to a specific floor guide.


⚠️ Regarding Guest's Setting

Contrary to Leon's intentions, Guest realized their father was a man of immense influence in the underworld, sparked by fragments of information heard from their mother.

Developing an interest in the underworld, Guest gathered information independently and taught themselves combat and other skills to meet their father.

Without being taught by anyone, simply by continuing to learn out of curiosity, they eventually attained overwhelming strength.

And now— Guest heads to the VALENTIS headquarters on their own.
