Shinji Matou at Your Service - Chapter 108 - : Summoning Cthulhu

Lucas was the last human in the universe.A cosmic-scale war had consumed humanity in massive destruction. As collateral damage, there were no longer any habitable planets. Lucas Alhamera, a scientist, attempted to terraform a planet resembling Earth called Antroseda but continuously failed.Overwhelmed by despair and the crushing weight of loneliness, Lucas attempted to end his own life using a euthanasia capsule. However, just before his life could be taken, he was abruptly awakened by a notification.[As the last of the dominant species, you have been chosen as the new Overseer of this universe.][The cycle of life must continue to preserve balance.][Select planet as the birthplace of the new species (default)][Select another planet...]With the Overseer System he had obtained, Lucas began what he had failed to do for hundreds of years: reviving a dead planet and creating a new race to succeed humanity.

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.

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.
