Comprehensive Guide to Agent Sirius: DLC Content and Verified Status

Agent Sirius is a mystery-themed RPG developed by Lunarian and published by Saikey Studios, officially released on April 10, 2026. The game has gained significant attention for its blend of high-school detective work and supernatural investigation, alongside a robust "Pleasure Corruption" system. Core Gameplay and Story

Players step into the role of Beni Akesuzu, the president of the Detective Club at Star Haven High School. While she appears to be an ordinary student, she is secretly an operative for Bancho, an organization specializing in supernatural threats.

The Mission: Investigate a series of strange incidents involving "Poison" monsters that use pleasure brainwashing to dominate the school.

The Partner: Beni is accompanied by her overseer and loyal partner, Nadeshiko Shiratora.

Investigation Loop: Players explore the school campus, gather clues, and interact with a cast of characters to identify eight potential suspects before the academy falls.

Combat Mechanics: Battle consists of simple, avoidance-based mini-games. The difficulty is intentionally low to prevent blocking story progression. DLC Content: Uragiri no Kingdom (RJ01259073)

The DLC, often referenced by its DLsite identifier RJ01259073, introduces an expansive sub-plot titled "Uragiri no Kingdom" (Betrayal Kingdom).

New Narrative: The DLC shifts focus to a "yuri marriage" between the hero and heroine, which is threatened by a new antagonist, Noroshi Ren. eng agent sirius dlc rj388166 rj01259073 verified

Dark Side Routes: It adds extended "bad-end" sequences where players can control corrupted versions of the heroines to actively spread influence rather than stopping it.

Verification: The "verified" tag often refers to the Steam Deck Verified status, confirming that the game's interface and controls are fully optimized for SteamOS. Key Features of the Corruption System

The game's defining mechanic is its "Pleasure Corruption" system, which creates a sense of escalation as the protagonist loses control.

Chain-Fall Design: Defeat in battle does not lead to a game over. Instead, it unlocks one of five distinct corruption types.

Reversibility and Spread: Once fallen, the protagonist can turn and ensnare her own allies, allowing players to experience the story from both sides of the conflict.

Visual Variety: The game features high-quality artwork by Sanatsuki, including extensive character portraits that change based on the current corruption pattern. Technical Specifications Agent Sirius - Steam Community

Part 9: Troubleshooting Common Issues

Even with a verified DLC, problems can arise:

Issue: Game crashes after patch install.
Solution: Run verify.exe again. If it shows "Patch mismatch", re-download RJ01259073 from the agent’s official source. Corrupted downloads are common.

Issue: Text is cut off or overlapping.
Solution: The default font lacks kerning. Download the agent’s recommended font pack (FreeMono or Noto Sans CJK) and place custom_font.ttf in the game’s root directory.

Issue: "Agent Sirius DLC not recognized" error.
Solution: This means you installed the patch over the wrong game version. Update RJ388166 to v1.08 or higher via DLsite’s update section. Then reapply the agent DLC.

Issue: Save file says "Japanese only" after English patch.
Solution: Verified patch v2.1 and above supports cross-language saves. But you must start a new game for the first run. Old Japanese saves will show garbled text.
