Akiyo Oshima was a successful man, with wealth, status, and a perfect life. However, by giving in to the temptation of betrayal, he awakened the wrath of the one entity he should have never angered—his girlfriend, Sayuri, who turned out to be Death itself.As punishment, Sayuri cursed him. Akiyo was stripped of his identity, his form, and even his gender. In every world, a new body would be created for him, allowing him to inherit memories and a random aspect of personality. Now, he must live as Shizune Accursed. But her new existence was far from a second chance. Trapped in an endless cycle of reincarnations, Shizune awakens in different worlds, with no control over her fate. And in each of those worlds, there's always a Yandere she has met or will meet, whose obsessive love inevitably leads her to her death—whether by possessive love, madness, or simply the need to have her all to themselves.Condemned to die over and over in the arms of those who love her in twisted ways, Shizune, in an attempt to understand the burden of manipulating others’ feelings, finds herself on a dangerous path. Will she survive and break this curse? Or will she remain forever trapped in a cycle where love is uncontrollable and always leads to death?Whether in a fantasy, futuristic, or modern world, where anything can happen, the question remains: who is really on Shizune's side? Are they allies she can trust, or just more Yanderes waiting for the perfect moment to seal her fate? Among men and women, even within her own family, Shizune will need to figure out who she can truly trust… before it’s too late.
