○ Confrontation

Based on these new clues, you can continue Interrogation, Confrontation, and further combinations.When all clues are gathered, the truth will reveal itself.

○ Worldview

Belmarc, a City-State where magic and science coexist.
After The Great Cataclysm, Belmarc became a city that could collapse again at any time.
Therefore, it placed “stability” as its highest value.
Risks are eliminated, possibilities are managed, and unpredictable beings are restrained.Can you push yourself forward within the current of order?

○ Scenarios

You can play five incidents intertwined with magic and science.
Each scenario unfolds independently, with an estimated playtime of approximately 1 hour and 30 minutes per scenario.

At his teacher’s request, Orin welcomes a girl who entered from outside the City-State.Her name is Aera.
She possessed incomprehensible power, yet was strangely human.That meeting, which began as a simple “favor,” soon comes into contact with the darkness of Belmarc.

Scenario 1, The Edge

On their way to the checkpoint, an unexpected incident falls before Orin and his companions.A mangled corpse, false testimony, and a Cognitus waiting for entry.In that gray zone where the hand of the law does not reach, judgment was always in someone’s trigger.

Scenario 2, Walking the Line

An audit dispatched to the Association, and two corpses discovered in the restroom.One person who existed at the same time, in different places.To follow the truth was always to cross someone’s line.

Scenario 3, What One Wishes to Believe

A victim of uncertain identityAn unconfirmed cause of deathThough we believe in many things as we go on living,
what is it that you wish to believe?

Scenario 4, What Must Be Done

The final incident where controlled justice and personal choice collide.

○ Characters

In Belmarc, a city where magic and science are intertwined, three races coexist.Humans possess neither magic nor transcendent computational ability,yet they occupy the center of Belmarc through their remarkable adaptability.Venerifa, a race that survived the witch hunts of the past,possess animalistic traits and can wield various forms of magic.Cognitus, mechanical lifeforms created for war,were recognized as sentient beings 78 years ago and became members of the City-State.In Belmarc, where interests clash,you will resolve various incidents as a Fixer.

Recommended Feb 26, 2026
I've gone through more than half of the first chapter, and so far the content seems quite rich. There are also a few minor issues that could be improved. - no fast forward, we need `ctrl` - 9px pixel font is illegible and squinted for Traditional Chinese, and 12px pixel font will greatly improve it. - only one save slot, [spoiler]When I accidentally opened the tutorial in the console, my save file just got reset. :( [/spoiler]
