World End Syndrome presents a compelling narrative tapestry woven with themes of identity, bullying, and supernatural romance, set against the backdrop of a city where the dead are returning to life. The visual novel boasts complex characters, largely well-translated dialogue, and an intriguing lore surrounding the Yomibito, beings who resurrect every century. However, these strengths are significantly hampered by a cumbersome game mechanic that transforms the journey to uncover the full story into a grueling endeavor.

Set in the seaside city of Mihate, World End Syndrome was not what the reviewer initially expected based on its title. While apocalyptic elements exist through the Yomibito legends, the core of the game focuses on a more personal, localized mystery. The gameplay loop resembles a dating simulation mixed with a choose-your-own-adventure. Players navigate Mihate after a lengthy prologue, choosing which locations to visit, such as the school, the seafront, or a local cafe. The critical issue arises because the game provides no indication of character locations. A player's choice of where to go progresses time, and this progression occurs even if the intended character isn't encountered.

To compensate for this, World End Syndrome expects players to frequently save and reload game files. Once reloaded, icons appear next to locations, indicating which characters were previously present. This save-and-load system, which feels like padding, forces players into a repetitive cycle. The reviewer suggests that a system akin to Persona 5, where character locations are visible without time penalties, would have been a more player-friendly approach.

One of the initially encountered characters is Saya, a member of the wealthy Kamashiro family. Initially appearing arrogant and cold, her arc gradually reveals a more vulnerable side, struggling with her sense of illegitimacy and her true parentage. This narrative, while leaning on tropes of the affluent character with a hidden heart of gold, is handled with elegance. However, even her story begins with fifteen days of brief, seemingly pointless interactions as she hires the protagonist as her assistant.

Saya's narrative takes a darker turn when she faces a stalker, who is revealed to be her biological father. Her struggle with her identity and insecurities culminates in a touching high school romance, only to end abruptly with her death at the hands of a Yomibito. This unexpected outcome left the reviewer confused and prompted the need to consult external guides to understand how to achieve a different outcome. It was discovered that the protagonist's death is unavoidable in certain paths, forcing players to complete the game multiple times to uncover the full truth.

To reach the "Truth" ending, which reveals the secrets of Mihate and the protagonist's shocking fate, players must experience all five romance routes. Miu's storyline is crucial, as her unique "Hawk's Eye" ability allows her to sense the unnatural state of the undead. While the writing remains strong throughout these playthroughs, the knowledge that only one specific path leads to the intended conclusion diminishes the player's sense of agency. The narrative reveals the protagonist's past trauma, including the death of his sister and subsequent online harassment, which drove him to seek a new identity in Mihate. The game explores the concept of "world end syndrome" as a metaphor for the traumatic shifts individuals face when their reality is shattered, suggesting that meaningful connections and empathy are the cures. This theme is unfortunately undermined by the character of Kensuke.

Kensuke, intended as comic relief, is described as one of the most detestable characters encountered. His actions, including attempting to photograph female students in compromising positions and exploiting Miu's vulnerability, are not only unfunny but actively detract from the game's mature themes. His presence, especially his interjections during serious discussions about the town's disturbing events, consistently breaks the immersion. The reviewer expresses a strong desire for an option to remove Kensuke from the game entirely, as his constant trivialization of sensitive situations negates the narrative's gravity and makes the difficult journey through the "world end syndrome" even less bearable.

Despite these significant gameplay and character frustrations, the underlying story of World End Syndrome is powerful and ultimately rewarding, provided players can persevere through its mechanical shortcomings. The game's intricate mystery and emotional character arcs are present, but they are buried beneath a frustrating and often tedious interactive structure and the presence of an irredeemably irritating supporting character.
