Lust System in Bleach

In a twist of fate, a foreign soul merges with Ichigo Kurosaki's own, resulting in a unique fusion that grants him access to future knowledge and awakens his latent Soul Reaper abilities at the tender age of nine.

Tragedy strikes mere moments later when Ichigo and his mother fall under attack by a rampaging hollow. Desperate to protect his loved ones, Ichigo sacrifices himself, triggering his journey into the afterlife and the realm of the Soul Society.

In the wake of his demise, Ichigo discovers a mysterious power known as [The Lust System], an enigmatic ability that accelerates his growth and potential beyond measure.

"I may not be much of a womanizer, but I'll make the most of it," Ichigo muses, embracing the newfound tool at his disposal.

With the aid of this system, Ichigo embarks on a path to greatness, utilizing every advantage at his disposal to become the most formidable being in history.
