[He would casually point at Horus, although he wasn't sure if it was the same kind that lives within the Abyss.]
"That. That's a demon. Some prefer being called deities but whether you are a god of fertility, the underworld, or even the sun... you are a demon, or an evil spirit."
[He would take a deep breath as he puts the ideas in order within his own mind.]
"As there are beings we record through mythology, religion and even urban legends... those images stay within our mind. Whether these ideas came to us first, or we created them from watching the real thing pass by, the truth is that Demons are all of them. Every devil, every type of angel, any and all legendary beasts from all points in history from every culture, within their realm, they are made real."
[He would stand up and walk up to TV screen yet again, placing his hand on the corner of it.]
"We call this realm the Abyss, although Mister Nakajima called it Atziluth, those siding with God call it Demon World, Makai within national occult texts. I think the term 'Expanse' is more popular these days, more so than my time's 'Abyss'. Anyways, demonkind in almost its entirety has been identified, and most have been grouped in different races. Tyrant, Fiend, Vile, Tenma, Avian... to name a few."
[He would put once more a single hand through the TV screen.]
"Now this is the important part and why learning how to deal with demons is important: This realm is one only but deeply connected to all reality, and it completely disregards the passage of time. What this means is... that any timeline and universe is in danger the moment a gateway is opened; these ruptures on space-time are usually permanent... that's what happened to my Tokyo back in 1992 when I was 15. Demons began invading and their sudden appearance took many lives, including my mother, Tokyo itself was pure chaos and then was bombarded with nuclear weapons and in the following years the entire world fell in a global conflict using demons as weapons. She saved me and then 30 years passed. When I came back during 2022 the entire world was in ruin. Everyone was gone, most humans had been killed."
[Kazuya would stop speaking, and softly gasps with both eyes open wider than before. He would remain static for a moment before retracting his hand from the TV and would then rub his left arm. His breathing had gotten heavier, but he would force himself to go back to his senses.]
"......The Abyss... and demons, are all born from humans. Just like Shadows are to individuals, demons are that to the entire human race as a collective. Demons are unhinged humans, in a way. They are for the most part sapient creatures or at least sentient, with some wishing nothing but our extermination while treating us as food, while others are happy to cooperate with us and live by our side. It's... a mistake to think of demons as monsters or animals. In a way... they are also part of humanity. What I teach is a way to deal with demons; if you can negotiate, you must, but if you cannot and words will do nothing anymore, you must be strong enough to fight, and skilled enough to kill them in one move."
