Raising Yanderes to save the world

Kael Arden had only one conclusion after dying twice.

Yanderes were disasters pretending to be human.

In his first life, Kael was a therapist specializing in emotionally unstable patients… until one of them became obsessed with him and killed him while begging him not to leave her alone.

He thought death was the end.

Instead, he woke up inside the fantasy world that had haunted his dreams for years—a world where he had once been the mentor of the legendary Hero.

While the Hero stood in the spotlight, Kael remained behind the scenes, guiding the heroines destined to become world-ending calamities.

The Saintess.

The Dragon Princess.

The Necromancer.

The Demon Queen.

Everyone believed those girls loved the Hero.

Until Kael died… and the girls destroyed the world trying to cope with losing him.

Now reborn years before the apocalypse, Kael wants only one thing:

Stay far away from emotionally unstable women.

That was the plan.

…But instead of falling for the Hero like they were supposed to, the future calamities have started becoming attached to Kael far earlier than before.

And with the mysterious Yandere Raising System forcing him to “save” them, Kael is beginning to realize something terrifying:

He may have been the reason the world survived for as long as it did.
