I'm Nagare Natsuru, and I Turned into a Kampfer from the Start

After being reincarnated on Blue Star in another dimension, the protagonist gets a new name: Sena Natsuru.

He carries a System that lets him copy skills possessed by people from other worlds in the anime multiverse.

He can use the magic of the Holy Queen from the world of Overlord,

and the Breath of the Flower taught to Makomo in the world of Demon Slayer.

Just as Sena Natsuru thinks he's living in an ordinary world where he'll never get the chance to use these abilities,

he saves Shizuku Sango, who is being hunted by a blue Kampfer.

Afterward, an unknown person sends him a harakiri doll?,

and then he turns into a Kampfer warrior?

Shizuku Sango: You saw me naked, so you're responsible for me.

Akane Mishima: You saw the student council president naked, so our relationship should go further than hers.

Mizuki Kondo: He's my childhood friend!!!
