In Greek myth, the dead drink from the river Lethe and forget their lives. In Below Lethe, they forget, but the river remembers. Korean two-person indie team Meisomi is preparing this story-driven psychological horror adventure set in the Greek underworld, and a demo is available now on Steam.
The game is a courtroom-style deduction game in which players uncover the truth of a case through the memories of the dead and prove the defendant’s guilt.
The visuals stand out first. The team says every illustration in the game was drawn entirely by hand, with no generative AI. Black-and-white art that preserves the texture of paper gives the underworld an eerie, absorbing look.
A Trial Built From the River’s Memories
Souls who cross the Lethe lose all memory of their lives. In this game, however, the memories the dead leave behind seep into the river and become the key evidence for solving cases.
When a soul stands trial, the memories of those who crossed before rise to the surface. They hold fragments of a life seen through the eyes of people who loved the defendant, hated them, or simply passed them for a moment.
The soul on trial testifies about their own life and fights desperately to defend themselves. But the game begins from a harsh premise: testimony alone can never produce a just verdict.
The Dikaion: Rebuilding the Past From Fragments
Players serve as the Dikaion, a prosecutor-like figure in the trials of the dead. They examine the fragmented memories surfacing in the Lethe to uncover the truth hidden beneath the defendant’s false testimony.
The deduction is precise. Players must work out how many people were in a memory, who they were, and the order in which events took place. Placing the right figures and actions on the “water of memory” then reconstructs what happened that day. The finished memory becomes evidence to present before three judges.
Using that evidence, players prove the defendant’s guilt and its weight and push toward a fitting verdict. The judges then weigh the revealed truth and the defendant’s final plea to decide the soul’s fate.
When an Obvious Verdict Unravels, and Two Endings
The first trial described on the Steam page starts simply. The defendant recounts their life, the memories surface one by one, and the guilt seems clear. But just before the verdict, one of the judges calls for a pause, and the trial begins again. A truth the defendant had concealed comes to light, and a case that seemed settled takes a new turn.
Once everything is revealed, the player makes the final call. The team says that even knowing every fact, choosing a single right answer may be hard. The story branches into one of two endings depending on the player’s choice.
Hand-Drawn in Black and White
Visually, the game leans on black-and-white illustrations drawn by the team and analog paper textures to build a distinctive, ominous atmosphere.
Meisomi emphasizes that every illustration was made entirely by hand without generative AI, and the Steam page carries hand-drawn and 2D tags.
About Meisomi
Meisomi, a two-person team, handles both development and publishing. The game supports Korean, English, Japanese, and Simplified Chinese for interface and subtitles; full audio is not provided.

Who This Is For
Strong fit for: fans of courtroom deduction games who want something darker and more mythic; players who enjoy reconstructing events from fragmented evidence; lovers of hand-drawn, monochrome art; players who value moral ambiguity and branching endings; Korean-language players, with native support.
Cautious fit for: anyone who needs a release date or price, since neither has been announced; players who prefer voiced narrative, as there is no full audio.
Less ideal for: those seeking action or jump-scare horror rather than slow-burn psychological tension.
The Takeaway
Below, Lethe takes one of mythology’s most evocative ideas, the river of forgetting, and turns it into a courtroom where the drowned memories of others become the only honest witnesses. Its memory-reconstruction deduction, a twist-driven first trial, two endings, and fully hand-drawn black-and-white art give a two-person Korean team a strikingly clear identity. The demo is the best way to step into the role of the Dikaion before the full release.
Demo available on Steam. Release date TBA.
