- New title from the two-person K-indie team Meisomi… Steam demo revealed
- A psychological horror adventure set in the world of the dead in Greek mythology
- Illuminate the story of the afterlife with hand-drawn black-and-white illustrations and paper textures.
South Korean two-person indie development team Meisomi is preparing a new story-driven psychological horror adventure title, ‘Below Lethe’ .
Set against the backdrop of the world of the dead in Greek mythology, this game is a unique courtroom mystery style work in which you uncover the truth of the case using the memories of the dead as clues and prove the defendant’s guilt.
What particularly catches the eye is the visuals. The development team revealed that all in-game illustrations were drawn entirely by hand without the use of generative AI. The visual presentation, which faithfully preserves the distinctive black-and-white art style and paper texture, is expected to deliver a peculiar yet deeply immersive experience.
The trial in the underworld conducted with memories remaining in the River Lethe
In Greek mythology, the deceased who cross the River Lethe are bound to lose all memories of the living world. However, in this game, the memories left behind by the dead seep into the river and become key clues to solve the case.
When a soul stands before the court, the memories of those who have crossed the river before rise to the surface. Within those memories lie the fragments of life as seen by those who loved or hated the defendant, or by those who merely passed by in a fleeting moment.
The deceased standing trial desperately defends themselves by recounting their life. However, amidst the harsh rule that a just verdict can never be reached based solely on verbal testimony, the real story of the game begins.
The deceased standing trial recount their lives directly and defend themselves. The game starts from the premise that a trial cannot be decided by testimony alone.
‘Dikaion’ reconstructs the event by piecing together memory fragments
The player takes on the role of ‘Dikaion,’ acting as a prosecutor in the trial of the dead. By closely examining the fragmented memories floating on the River Lethe, they must uncover the truth of the case hidden beyond the defendant’s false testimony.
The process of deduction is quite sophisticated. One must accurately determine how many people were in the memory, who the figures were, and in what order the events unfolded. Then, by properly arranging the correct figures and actions on the ‘water of memory,’ the events of that day are vividly recreated. The memory thus completed becomes evidence to be confidently presented before the three judges.
Based on the evidence, the player must prove the defendant’s guilt and gravity in detail to arrive at a fair verdict. The judges will ultimately determine the fate of the soul by synthesizing the revealed truth and the defendant’s final plea.
The moment an obvious sin is overturned, and two endings
The first trial introduced on the Steam page begins ordinarily. As the defendant recounts their life and memories are revealed one by one, the guilt seems obvious. However, just before the verdict, one of the judges says, “Wait,” and the trial restarts. The truth the defendant has been hiding is brought to light, and the case, which was thought to be closed, enters a new phase.
Once the truth is fully revealed, the player must make a final decision. The development team explained that even knowing all the facts, it may be difficult to choose a single correct answer. Depending on the player’s choices, the story leads to one of two endings.
Hand-drawn black-and-white illustrations and paper texture catch the eye
In terms of visuals, the development team actively utilizes hand-drawn black-and-white illustrations and analog-style paper textures to create a unique and eerie atmosphere.
In particular, Meisomi emphasized that all illustrations used in the game were created 100% by hand without the help of generative AI. In fact, the tags ‘Hand-drawn’ and ‘2D’ are proudly listed on the Steam page, raising expectations for the unique handcrafted feel characteristic of indie games imbued with artisanal spirit.
Development Team Meisomi and Pre-launch Status
Development and distribution are handled entirely by the two-person development team, Meisomi. Supported languages include Korean, English, Japanese, and Simplified Chinese, all of which support interface and subtitles, but full audio is not provided.

‘The River of Lethe’ is a work with a unique setting in which scattered memories are combined to recreate the past, and a legal battle is waged using this as evidence.
In particular, it is expected to appeal to gamers craving a weighty, narrative-driven psychological horror adventure, as it goes beyond merely determining guilt or innocence to entrusting the weight of the sin and the final fate of the soul into the player’s hands.
