Inheritance

Rei held Aiko as they were walking toward the city of Camelot. Rei wanted to come here as it meant that he would be ascertain what time it is during the holy war. Making two cloaks Rei covered both him and Aiko.

"This will help us hide from other people senses." Rei said with a smile as he looked at Aiko. She nodded as she hung the hood lower. Leaping to the roof, Rei made some silencing seals to silence his foot steps as he jumped across from building to building. Rei could see that Camelot was overrun with demons.

'hmm, I hope that Arthur hadn't died yet, I don't want Merlin to be sad.' Rei thought as he sent out his haki. He could feel that the city was mostly filled with demon life signitures while there was a power human life force going towards the castle. Rei smiled slightly as he couldn't feel Meliodas' signiture.

'This either means that dad hadn't lost his emotions and is still with Eli chan or that he did and is somewhere else. I'd much rather the first option.' Rei thought while he leaped towards the castle and walked calmly. Walking through the walls, Rei could really marvel at the infrastructure.

"Aiko chan, this place is quite amazing isn't it?" Rei said as he showed Aiko the decorations.

"?How do you know my name? I havn't told you yet." She said tilting her head.

"Errrr....

*BOOOOMMMMM!!!!!!

A sudden explosion cut Rei off as he looked towards the direction.

"Lets go Aiko chan, there is something interesting over there." Rei said as he switched topics and walked over to the location.

Rei sat on top of a wall with a smile as he and Aiko watched what was happening.

"Why don't you help?" Aiko asked.

"Hmmm, because it's coolest to arrive just before disaster?" Rei said with a slight tilt of his head.

"Like a hero?" Aiko said turning her head to Rei.

"Huh, I suppose so. After all, years ago I did want to become a hero." Rei said with a smile as he remembered about his life in Boku no Hero Academia.

"I did? So you don't want to be a hero now?" She asked.

"You really ask the hardest questions now don't you. Well I suppose it's because there is no good or bad. There is only the zone in the middle and some people are just lighter to darker. Everyone has their own back story and while I may be a hero to someone, it also means that I'll be a villain to someone else." Rei said as he looked towards Arthur who pulled out Excalibur.

"So your a lighter shade of grey?" Aiko questioned as she looked towards Rei.

"Hmm, I'd say I'm more in the middle as I have done evil things to people." Rei said.

"Well you're a lighter shade of grey to me." Aiko said as she leaned more on Rei.

'Stockholm syndrome? Well I did kill her mum and take her with me.' Rei thought as he gave Aiko a side glance before looking back at Arthur. Right now, Arthur was using the techniques that various human legends had left behind in Excalibur.

"He's going to die." Aiko said out of nowhere as she looked at Arthur fighting back against top ranked demons.

"Hou~ How can you tell." Rei said with curiosity as Aiko was able understand what was happening.

"Weak points are showing up everywhere on his body while the two demons don't have a single one that was hit by him." Aiko said shocking Rei slightly as Aiko was able to see the weak points of people.

"How can you tell that these are weak points?" Rei asked wanting to confirm.

"There are red dots everywhere on their bodies." She said simply.

'She would be perfect to be an assassin with this talent.' Rei thought.

"AAAAHHHHHHHHHRRRRRRRRRGGGGGGGG!!!!!!" Arthur screamed in pain as blood could be seen appearing every where on Arthur's body.

"Righto, it's my turn now." Rei said as he stood up. He was about to set Aiko down when she grabbed him signalling him to bring her along. Rei only shrugged as he jumped down.

Cusack, one of the highest rank demons, crouched near Arthur as he looked at him and spoke.

"You made two grave mistakes lad. First is your fatal lack of power, I'd wager that the sword contains countless souls of countless human heroes and granted you power. But with that the strain was much bigger. I'm sure that you trained yourself but you couldn't reach their level so now your body is destroying itself. And the second...you trifled with the wrong opponents." Cusack said as he was about to use his ability to control Arthurs' body.

"You made one too, no detecting me." Rei said as he placed a hand on Cusack's shoulder shocking everyone as Rei seemed like he appeared out of nowhere. Cusack couldn't move as he was drenched with sweat. The pressure he felt from Rei was on par with the demon king and could easily kill him at any moment. Rei threw Cusack backwards as the body made a shockwave as it collided with Chandler, who was also one of the highest ranked demons.

Merlin appeared a split second after Rei threw Cusack as she was about to attack him. She was shocked at the sudden appearance of this duo as even she didn't detect them. One small and one large, the pressure she felt from the large figure was the same as what she felt from the demon king and the goddess.

Rei waved his hand as he healed all of Arthurs injuries with nature magic while Merlin was about to attack due to the fact that Rei might of wanted to harm Arthur.

"Who are you?" Merlin questions on guard in case Rei tries anything.

Rei chuckled slightly as he lifted his hood.

"It's been a long time Merlin how has it been?" Rei smiled as Merlin hugged Rei.

"You have no idea how worried I was when you disappeared." Merlin said.

"Well let's talk later, we need to get Arthur out of here first." Rei said as he separated from Merlin. She nodded as she teleported all of them away.

Landing on Hawk, everyone of the 7 sins where shocked at the three new additions that Merlin returned with. Removing the cloaks completely. Rei grinned.

"Yo!" Rei said while Aiko gave a small wave towards the group.

"REI CHAN!" Diane shouted as she shrunk down and gave Rei a hug. Rei only smiled wearily when he saw King looking at him with jealousy.

"Rei." Meliodas walked out with Elizabeth while he smiled as Rei.

Seperating from Diane, Rei looked towards Meliodas and gave a grin.

"How is everything going with Eli chan?" Rei asked as he gave a shit eating grin. Meliodas grinned back as his made an ok sign.

"So mind bringing me up to date?" Rei asked.

"Sure but first who's the kid?" Meliodas asked pointing at Aiko in Rei's arms.

"Oh her? I picked her up on the way to Camelot. Her village was completely overrun by demons." Rei said.

"Haaa, like father like son." Merlin said as she walked over since Diane helped bring Arthur to a room to rest.

"What do you mean?" Aiko asked curious.

"Well Meliodas here also picked up Rei when he was a baby on his way to Liones." Merlin said.

"So Rei isn't shorty's real son?" Aiko asked tilting her head.

"Ay, don't call dad shorty." Rei said as he gently bopped Aiko's head. She held her head as he nodded.

"Dad adopted me so I'm not his biological son." Rei explained to Aiko.

"Are you going to adopt me?" She asked.

Rei thought about the things he will be going through. The higher realms, enemies and most importantly going to different worlds.

Rei then shook his head.

"I can't, I'm going to be going to much more dangerous places and I can't protect you if I did take you with me." Rei said as Aiko looked down.

[Host, if Aiko breaks the barrier of ranks herself, she would be able to go to the higher realms but not the different worlds.] The system displayed it's message.

"How about this, I'll give you something to help you get stronger. And it will tell you what to do to find me. So that way you'll be able to decide whether you want to follow me or not is that ok?" Rei asked as she looked up at him and nodded.

"Right guy's I'm going to make something for Aiko, if there is anything important tell me after I'm done is that ok?" Rei said as he asked the group.

"Sure go ahead Rei chan." Merlin said with a smile while the rest nodded.

Rei nodded as he took Aiko to a lab he made in the boars hat years ago.

"Right then Aiko chan, I'm going to make an inheritance seal which imprints some of my teachings into your soul. What you do with it will be up to you, but if you decide that you want to join then at one point it will remodel your body to make it so that you will be able to reach my strength ok?" Rei asked one more time to make sure. Aiko nodded as she started to watch Rei make his inheritance seal.

'What should I give her...Mana control, body control. I should also give her a way to make her own Zanpakuto...' Rei though as he started to make the seal. It contained a weaker form of Unlimited phantasm works which is only usable once to help her make a Zanpakuto. He then started to add different techniques and ways to understand concepts and laws. How there was another level beyond laws and the tribulation to reach divine rank. Higher realms and finally a weaker version of instance that can be used by her and her only as the technique is bounded to her soul, sage mode and how to achieve it.

Adding a drop of his blood, Rei made it so that when she was sure that she wanted to follow him, it would convert her to a vampire. Granted that it needed her permission. Rei also started to make some slight changes and made it so that she only need mana instead. As a final touch, Rei made it so that it would be able to save her life a total of 5 times by summoning a portion of his power. Rei started to stablise the seal as he wanted to make sure that it didn't harm Aiko in anyway and that even if she didn't want to follow him, it would still protect her 5 times regardless. To help her out, Rei made some instructions on how to access each of the inheritance so that she won't be lost.

"Ok, Aiko chan, are you ready." Rei said as he looked over to Aiko, she nodded as Rei then sent the seal into her soul and directly imprinting itself to her soul so that it would follow her even if she were to reincarnate in case she changed her mind. Aiko didn't feel a thing but knew how to access it.

"Thank you." She said as she looked at Rei.

Rei only smiled back as he held her in his arms once more.

'To think that I'm able to give out inheritances now...' Rei though as he walked out of his lab.
