Chron: "You said that you will teach me demon's magic. So why are we heading to Asura's house?"
Old man: "Because he's more suited to teach you about this magic. Wel, mainly because he is 'Sin' bearer."
C: "Sin bearer? What is that? I have never heard of something simmilar to this when I was still in my hometown."
O: "Well, it's due to the fact that Asura is also very old."
C: "Unlike certain someone, he looks very young."
O: "Sometimes I want to rip your head off."
C: "Hehe."
Old man and Chron went to Asura's house.
C: "Hi Asura. It's been a while."
Asura: "Yup, good to see that you're progressing in your magic."
C: "I want to put it straight. Can you teach me demon's magic?"
A: "I guess I will do it.
So let's start with the basics. Unlike angel's magic, which is mainly focused on buffing allies, demon's magic is to debuff. It might be with using weakening spells, poisons, sleeping attacks or even mental attacks.
Inferior form of demon's magic is dark magic, but don't mistake it with black magic.
Black magic is terrifying and is also a huge taboo in a lot of places.
With black magic you can cause discomfort to other people and only few chants can really kill opponents. But with demon's magic it's different. You can for example curse someone and make it so he/she will die after certain amount of time. Of course it requires a lot of mana but you aren't the type to lack it so it won't make too much difference for you. I nreality your mana pool might be comparable already to stronger adults.
The basis of demon's magic and dark magic is negative energy. People's grudges, angers and much more things that can produce negative energy caused creation of those two magics.
The biggest source of negative energy is people's sins. They can produce huge amount of negative energy and you can just take it from your surrounding and use it.
Of course it's not everything."
