I'm looking for a manga where the protagonist is a boy (teen?) who fights monsters with his artificial partner.
- the monsters are created when 2 "seeds" (inside a persons body) come in contact with eachother, making the "hosts fall in love"
- the protagonist doesn't beleave in love and refuses to except any evidence of love.
- the partner is a manmade "container" to store the defeted monsters
- the partner is female, wears a bunny ear headband, and carries around a giant stuffed bear (bunny?)
- she would be described as a loly in her looks and dress
- the protagonist wears a hoodie bunny ears on it
- he fights with a weapon (scythe) made from his blood/essence?
- he works in a company where fighting these monsters is their job
- he suffers from a tramatic past and goes haywire a few chapters in.
