I think this topic is strongly needed. Since there are so many demons in the world that no human can know all of them. Since this is school of onmyoji I'm sure sooner or later some of the students will meet a demon. That's why I want to ask ppl who met any demon to write a maximum information about him here. We need our own archive about demons. I'll write an example. I've met a demon that looks like black shadow about 2.3 meters tall. It has scary white face that looks like a mask. Around him is always pitch black darkness. He provokes a human to walk into the darkness where he attacks him and drains his spiritual powers. 3 seconds is enough for him to drain more then a half of your spiritual powers. So be very cautious. He fears of gods powers so you can drive away him easily with any of the spells you learn here. He can also read your mind. So be careful. After he attacked you he might attack your friends and family or ppl you've just met. Even on the internet.
Right. Please write here everything you know. Also while batteling try to learn about demon as much as you can. Thank you.

i dont have the third eye so i cant see demons for now. are there even demons on the net? how come only u and Abe have met them? how can u fight demons on the net?@_@

i have no fighting experience so far, the most nasty things i've encountered so far are just ghosts.

but i would like to share about a demon from the visions of my friend. these demons appear from shadows, i have no physical details about them as they are of different shape and sizes but they cannot come out of the shadows to attack when there is light. but they are smart enough to destroy every single source of light emitting device or thing so that they may attack. these creatures destroyed an entire powerful civilization (which are skilled in dragon hunting and has killed my friend's family including him in the past) in a single night. Be careful of them as they might be in this world as well, light is they're only bane so far. they cannot come out of the shadows when there is light, but they are smart enough to destroy even torch lights from a distance so be careful.

Thank you for sharing some information ^^ It would be easier to exorcise demons if we know something about them. But these demons seems to be very dangerous creatures...
There are no demons on the net. But demons can read one's mind. That means if you having a conversation with someone on the net, that person's demons might attack you. No matter where you and that person live. The demons can reach you if they will find you in memories of your conversationer.
