Airi POV (our mc is dreaming is what she thinks, it's all just dreams. We know it's her past memories though. This is centuries before the 1st and 2nd rift wars that happened with the 3rd gen) 

768 A.D. (Ariel's death) according to the dragon's calendar year

"Kana it wasn't so bad," Airi sighed. 

"You call Elis escaping after clawing her threat from a arranged marriage not bad," Kana shouted. 

"Normally we don't interfere with humans or dragons," Airi corrected.

"So your saying this isn't a exception then," Kana asked. 

"No it's fine the longest she's alive. The Phoenix 15th generation princess has escaped from the dragons marriage. Told you she couldn't stand it there," Airi smiled. 

"You know what happened last time we helped someone by had," Kana said. 

"Of course it was a national class disaster. We changed his fate from dying by the hands of the pure angels 5th generation. (Pure angel is used by them to refer to angels without a taint of human blood. When they refer to angels without saying pure it means they have mortal blood.) Then again, you begged us to save such a pure innocent soul but what happened to him." 

"I know I was wrong! Ok, you win this conversation. I didn't know he would demonize and wreck havoc on half this world," Kana shouted.

"Younger sister your not in the wrong. We had no way to see the future then. What's done is done. Besides you went into traveling in remorse over his death. After all he was your student," Airi said softly. 

"Sister how's your daughter, Akemi," Kana asked. 

"I know you hate when we sisters fight so what do you think," Airi sarcastically said. 

Kana gave a stiff smile as Airi gave her a sharp look. 

"How's Aoi then," Kana asked. She wanted to break the silence that was being made as Airi stared at her. 

"Oh you had to ask, what do you think it's been centuries but she's still in her baby form after what her father did to me. Aoi was almost turned into a still born if I didn't put her into that machinery into deep sleep she wouldn't be alive now," Airi shouted as she banged her hand on the table. 

Her cup of tea spilled all over as the floor cracked from her hit as the table spilt into millions of pieces.

"I guess your hatred for men came from how he betrayed you. Him almost breaking your mind after getting your trust has changed you so much. I'd rather have the calm cool headed sister back," Kana stiffly smiled. 

"Really then my hate shouldn't be affecting others too much," Airi said nonchalant.

"No sister whenever we go to public you give such a dense killing intent and aura to men. Yet your normal to women, can you tell me what he did to you that changed you so much," Kana asked. 

"I won't say much of it but one of the reasons I he left me in the depths with those soul reapers." 

"Yuck you mean the A ranked, ones those things are nasty they eat a human while it's soul is still in the body and they enjoy eating them raw with bloods and guts. Don't tell me he left you to them," Kana shivered. 

(Soul reapers have ranks S, A, B, C, D, E, F, G. They each skip a rank the most nasty is A rank soul reapers eat souls while humans or other races are inside that body. Where as soul reapers S rank fight them to keep the peace of those worlds as well as guide souls. They pretty much maintain the balance of worlds. Soul reapers Ranks: S

"What do you think. That's one of the things he did to betray me there were a lot more he did. I won't name all of them."

"So he trapped you there for a bit," Kana sighed. 

'No wonder my sister looks at men with so much hate. What else did that idiot Dark Elf do to betray my sister's trust,' Kana thought. 

"By the way sister just a question why do you care if I look for him for revenge," Airi asked suspiciously.

"Just this isn't like you," Kana joked.

"I wonder about that. I don't go killing children (boys) but I'm fair to all I see."

"You've change a lot sister. How are you taking care of Akemi," Kana asked.

"Hm easy I left her to train in the dark elf forest. (To hunt his relatives) To survive the forest of course. Oh and I told her all about her father. No details left out. She must be so pissed about her younger sister still in a baby form being developed inside that machine."

'No sister your creepy smile like he deserves it is leaking. And you shouldn't go telling her about what he did to you so easily! She's a child that's just 6 years old. 600 years old by human years but to us that's nothing we count her as 6 year old. But you shouldn't even leak info to her about it. Wasn't it supposed to be between you and your ex,' Kana wanted to scream.

"But wouldn't you rather get back at him in a round about way so he can't do anything back," Airi reasoned.

"Wait it's messed up to use her like that," Kana said.

"Well it's great for her to train her assassination skills."
