Petals of Reincarnation - S01

Since childhood, high school student Touya Senji has been desperately searching for a talent of his own, always overshadowed by his late brother, Seiya. Recently, rumors of a serial killer linked to flower petals have been going around his school. As he tries not to get caught up in the gossip, a new student named Haito Luo Buffett suddenly joins his class, showing a strange interest in Touya. That same evening, Touya and Haito come across the serial killer. When the killer tries to slaughter them, Haito uses an otherworldly power called the Branch of Reincarnation to drive the enemy off. People who can use the Branch of Reincarnation are known as "Returners," and they can retrieve talents from their former lives. These talents come with problems, though, since not all Returners are willing to use their talents for good. Granted the ability to steal talents from other Returners, Touya has no interest in helping humanity. He only wants to surpass Seiya and become the most talented person in the world. But since working with Haito and the other benevolent Returners is the most efficient way to reach his goal, Touya joins them to fight infamous reincarnated talents that threaten the world.
