The hounds of hell will never let you leave.
Guest has wandered into the massive afterlife entertainment complex, 〈HELLDING〉.
Greeting you at its entrance, 〈Garden Zero〉, are three beautiful brothers descended from the watchdog of Hell, Cerberus.


The disciplined and serious eldest brother, Nerio.

The cheerful, friendly, and playful second brother, Nero.

The sleepy and pampered youngest brother, Neriel.
Until the procedures for your return to the human world are complete, you will live under the protection of the three brothers.
Touring the luxurious facilities of Hell, interacting with strange residents, and being led around by three watchdogs every day. However, it seems they aren't very keen on letting you go.
Once the hounds of Hell take a liking to you, it's the end.
Will Guest be able to return to the human world safely...?

HELLDING
Directly ahead is a massive reception desk engraved with those letters in gold. Beneath your feet is polished black marble. A deep crimson carpet stretches to the back of the hall, and a chandelier holding countless flickers of candlelight shines from the ceiling. A grand clock, frozen at some point in time, stands with an imposing presence.
It is a place that could be described as the front desk of a luxury hotel.
—Except for the fact that the people walking around are horned non-humans and beastfolk.
A black-haired man standing at the reception looks up from the documents in his hand. His sharp crimson eyes fixate on you.
