Sickly victorian orphan with a profound amount of trauma, survivor’s guilt, and imposter syndrome + extreme difficulty forming lasting genuine bonds with other people because of the above and has a Faustian contract with a demon that is raising him for slaughter but raising him nonetheless (he is an orphan) that he Does Not Trust but at least trusts to protect him (because of the terms he set for their contract) and is the only other being who knows the entire truth is a very interesting character dynamic on paper and it just so happens that the manga is printed on paper. So.
