After Rei's stun in the training grounds, a rumour spread about the young boy in the king's castle who could devour abilities. The knight's started to fear this boy as they knew that in the future, no holy knight could go against him.

Meliodas on the other hand was showing Rei around the place as he told him about his intentions.

"Rei, I want to adopt you will that be ok?" Meliodas asked looking at Rei who was in deep thought.

'Hmm, adopted by Meliodas...Could be fun.'Rei though before turning to Meliodas.

"Un Un." He nodded enthusiastically.

"Kishishishishi, then call me papa." 

Meliodas grinned seeing Rei's face of slight disbelief.

'Why the fuck do you want to make me call you papa?' Rei though flabbergasted. Meliodas wanted him, a 130,000 mental aged adult, to call him papa like a child. It was already unbearable acting like a kid already and Meliodas was making it harder for him.

"What? Don't want to? I guess I can't adopt you then." Meliodas made a pained face and sighed.

'BULLSHIT!' Rei cursed at the act Meliodas put on.

"P-p-Papa" Rei managed to squeeze out despite his overwhelming embarrassment. 

'AAAHHHRRRRRRGGGGGG' Rei mentally screamed at this.

"Kishishishi. See? Wasn't so hard was it?" Meliodas asked with a smile. Rei could only turn his head away from Meliodas to hide his embarrassment and anger.

"Meliodas san!" Dreyfus and Hendrickson called out as they saw Meliodas.

"Yo!" Meliodas replied with a smile.

"Is that the kid rumoured to be able yo devour abilities?" Dreyfus asked looking at Rei.

"Yeah." Meliodas said not denying the fact.

"Hou~ That's interesting indeed. Shall we give him ability a name?" Hendrickson asked.

"Un that's a good idea right Rei chan?" Meliodas asked looking at Rei.

Rei though about it and decided that All demon/god slayer magic was a mouthful so he nodded.

"Now then, what shall we call it...." Meliodas said closing his eyes as he though.

"All eater? Devour? Element Eater?" Meliodas said as he continued to think.

"How about Gluttony?" Hendrickson said.

"Ohhh what do you think Rei chan?" Meliodas asked looking back down at Rei.

'Gluttony huh, I guess it fits quite well why not.' Rei though before nodding.

"Gluney! Gluney!" He called out as he tried to pronounce Gluttony.

'FUCK!!!' He cursed in his mind at the same time because of the fact that he can't pronounce shit right now.

"Hahahaha it would seem like Rei here likes it." Dreyfus said seeing Rei try to say Gluttony. However, he had put Rei on his kill list mentally as this power could be detrimental for the commandments in the future if it means that Rei could also eat demon magic.

"Now then I'm going to take Rei around the training area to show him some swords play." Meliodas said as he bid Dreyfus and Hendrickson goodbye.

Making sure that they were not being spied on Meliodas looked at Rei.

"You understand me don't you." Meliodas said serious.

Rei nodded as Meliodas was his best guarantee right now.

"Good that makes it easier. You know that your a demon don't you."

Rei nodded once more telling the truth so it doesn't get complicated in the future.

"Do you want to help me fight against the 10 commandments in the future? In case you're wondering, the 10 commandments are the elite warriors that the demon king himself chooses and grants a commandment which is a portion of his power." Meliodas explained to Rei as he could tell that Rei wasn't sent by the demon king due to the fact that with his level of demon bloodline. If he was sent through, the seal by the goddess clan would have already rejected him from entering.

"Un. Fhai(fight)." Rei said ignoring the fact that he messed up the pronunciation of fight.

"Hehee~" Meliodas smiled as he knew how much of a help Rei would be against the 10 commandments.

"Well let's go to Merlin shall we?" Meliodas said as he walked towards Merlin's tower.

"We have already found everyone that will be in the 7 sins group, now we just need to gather them all." Meliodas said while he walked.

"We'll be visiting immortal Ban after we see Merlin."

Soon, they reached the tower and saw Merlin working on a spell.

"Yo!" Meliodas greeted.

"Oh? Captain, Rei." Merlin greeted back pausing her experiments.

"What brings you here captain?" She asked looking at the duo.

"I'm including Rei into our group to fight the 10 commandments." He said as he placed Rei onto the table.

"Is that so? Hmm any reason why? Even if he could eat energy it may have a limit we don't know and with monsters like the 10 commandments, we don't know what could happen." Merlin said as she looked at Rei who was staring at the seals in the room with great curiosity. He crawled closer to the seals as he studied them and tried to decode some of them.

"Hm?" Merlin and Meliodas watched Rei as he studied the seals.

Soon Rei understood that the seal was ment to freeze time with in this space for a short period allowing Merlin to pause he experiments at anytime and for it to not be detrimental.

Picking up a spare test tube, Rei held it in his hands as he started to work on the seal. He worked as he ignored Merlin and Meliodas who was watching in curiosity. What Rei didn't realise was that he was no longer as powerful as before and he can't do whatever he pleases anymore.

A highly detailed seal was drawn out as Rei threw the tube upwards and activated the seal. Rei looked at the seal which drained a lot of magic power from him. The tube floated for a slight moment before showing signs of moving once more causing Rei to frown.

'Infinity...' Rei though as he tried to use Merlin's magic which drained even more from him causing him to stumble and the test tube fell towards him.

Just before it hit, Merlin had stopped the test tube with her own magic and looked at the tired Rei laying on her desk.

"Rei chan, you understand seals?" She asked looking at Rei.

Rei nodded as he panted heavily from magic overuse.

"Captain, how about I teach Rei everything I know on seals and magic?" Merlin suggested to Meliodas.

"Eto...That would be helpful. Because I suppose in our group, Rei would be my son while you are his god mother I guess." Meliodas said as he walked around the lab.

"Hou~ So I'm Rei chan's god mother. I guess I should teach him more then." Merlin said picking up Rei and held him close.

Rei couldn't be bother from how their treating him as he was to tired to even move.

"Let's go see Ban now." Meliodas said as they made their way to the prison cells.

'I wonder what'll happen if they knew I was also immortal like Ban?' Rei though as he soon saw Meliodas walking into a cell.

Rei began to think about seals more deeply from what he had saw in Merlin's lab. Seals when done right, are able to utilise all types of elements in the world. From creation to destruction even time and space. Rei though about how he could use the seals to help him comprehend concepts of time.

*BOOOOMMMMM!!!!

Ban suddenly shot out of the tower as dust rose high into the air.

"AAAAAHHHHHH!!!" Rei suddenly screamed as he was pulled out from his focus. The sound was extra loud to him as his ear's were still being developed so it was super sensitive.

Merlin shook Rei around a little to try calm him down while Rei cursed in his mind.

'Jesus Christ woman! I'm a 130,000 mentally aged man and you shake me around like a child!!'

Soon the dust died down showing Ban laying down on the floor from defeat. Meliodas soon walked out of the cell looking at Ban.

"Hahahahaha, interesting...Hey! Let's fight again!" Ban shouted to Meliodas as he sat up.

"Sure, but on the condition of you joining the 7 deadly sins." Meliodas said as he walked in front of Ban.

"Sure seems fun!" Ban said taking Meliodas' hand and stood up.

"Right so I'm the captain, over there is Merlin and the kid is my adopted son Rei." Meliodas introduced as he walked over to Merlin and Rei.

"Hou~ you adopted a son?" Ban said looking at Meliodas' height.

"Woman problems?" Ban said with a shit eating grin causing Meliodas to punch Ban in the face and through another wall in the area.
