"Stand in the ashes of a trillion dead souls and ask the ghosts if honor matters. The silence is your answer"
"I said my sword was a tool of justice. Not used in anger. Not used for vengeance. But now... Now I'm not so sure. And besides, this isn't my sword!"
"One sword keeps another in the sheath. Sometimes, the threat of violence alone is a deterrent. Sometimes, by taking a life, others can be preserved.

"What does it take to end a war? Well, if both sides wish for peace and set aside their hatred... No. Warfare is nothing but a means of negotiation between states. Wars break out even when there is no hatred. Territory, resources, or interests that you are determined to own. Ideology, religion, pride. Wars are fought over those objectives all the time. Meaning that when those objectives are met, the war will end. That, or the war will end when the human cost outweighs the gains. Anger and hatred are only tools to tilt a war in your favor. I'm not interested in those emotions. So I wouldn't hate anyone just because they're Martian."

"Absence of evidence isn't evidence of absence."
"To rule time is to rule the world."
"I need power to get revenge. As long as it's within my reach, I don't care if it's from a demon or a devil."
"That's right. Humans will do anything for their family. Even if it means shamelessly lying or turning into a devil or demon. If that's vile, then fear our depraved acts and keel over, vampires!"
"To kill a monster, you must become one!"
"Some walks you have to take alone."
"Fake people have an image to maintain. Real people just don’t care."
"People will stab you in the back. And then, they'll ask why you're bleeding."
"When a person lies, what is important is not the lie itself. No, it is their reason. Their why"
