After a bit a ship arrived as the hatch opened the captain walked out and blue team saluted

Y/n : "Sir what are you doing here"

The captain smiled

Captain : "Blue team great job again, and without air support you are dismissed"

Blue team headed to the ship while the captain turned to the group

Captain : "I know you all must have a lot of questions, why don't we have a chat in private please follow me"

Timeskip

In a large room was the 4 Satan's, Michael and Azazel and the rest of the group was behind them, and the captain of the ship they were on had Blue team stand behind him

Captain : "now I believe that introductions are in order"

After they all told their names the captain spoke up

James : "while you can just call me James, and behind me is Blue Team, so I know you all have some questions"

As they were asking questions Y/n couldn't take his eyes off Kuroka and Koneko, he couldn't help but want to ask them about if they are really his sisters, this didn't go unnoticed Blue team could see Y/n really wanted to know if they were his long lost sisters just then Master Chief spoke up

Master Chief : "Sir promission to speak freely"

James : "granted"

Master Chief : "I would like to ask a question of my own"

Sirzechs : "and what would that be"

Master Chief : "my question is for those to"

He points at both Kuroka and Koneko who looked back at him

Master Chief : "you said your name is Toujou correct, does this mean your sisters"

Kuroka : "yes"

Master Chief : "do you have a brother by any chance"

Koneko : "how do you know about that"

Rias : "Koneko you have a brother???"

After the girls told everyone that when their race was being attack their brother stayed behind to give them time to run, after they finished everyone understood

Rias : "so that's why you would always leave on the same day every year"

Kuroka : "yeah we made a grave for him and we go every year to visit it"

Asia : "what was his name"

Koneko : "Y/n, Y/n Toujou"

Y/n's eyes widen while his team and the captain just smiled, Y/n looked at his captain who smiled and nodded just then Master Chief turned around and walked back but as he past Y/n he put his hand on his shoulder

Master Chief : "it all up to you now brother"

Y/n : "thank you"

James : "Blue team please introduce your selfs"

They each took turns at taking there helmets off and stating their names

Master Chief : "John-117, Assault Co leader for Blue Team"

PO1 : "Kelly-087, Scout member of Blue Team"

LTJG : "Frederic-107, Assault and CQC Member of Blue Team"

PO1 : "Linda-058, Marksman member of Blue Team"

Just then everyone looked at Y/n who took his helmet off, as he did they saw his white hair and Hazel eyes

Y/n : "Y/n Toujou, Leader of Blue Team"

Just then everyone was shocked apart from Blue team and James who knew Y/n's past, just then everyone heard sniffling they looked to see Koneko and Kuroka on the brink of tears

Kuroka : "Y...Y/n is that really you"

Y/n smiled

Y/n : "Kuroka, Shirone you've both grown up a bit haven't you"

Just then cat ears appeared on Y/n and his tail came out of his Spartan armour, just then Koneko and Kuroka ran to him crying their eyes out and soon started hugging him as they did Y/n gave his helmet to Kelly and began hugging his sisters back

Y/n : "I missed you both as well"

After a bit

James : "Y/n why don't you and blue team take your sisters a go catch up while we finish up here"

Y/n : "thank you sir"

As they left the group looked happy all but Issei who was annoyed

Timeskip

Sitting at a table Blue team sat with Kuroka and Koneko as the siblings caught up on somethings, they were shocked to hear Y/n has been cured of his sickness for sometime and is now fit as a horse

Kuroka : "hey Y/n can I ask you something"

Y/n : "what's that"

Kuroka : "why Is everyone looking at us"

They turned to see every recruit in the cafeteria looking at them with stars in their eyes

Kelly : "your brother is kind of a legend here"

Koneko : "your a legend here"

Kelly : "you should hear what the girls say about him"

Y/n : "don't go there Kelly"

Blue team smirked while Kuroka and Koneko glared at Y/n

Kuroka : "oh, what do they say"

Keely : "oh nothing much just how strong he looks, and how they want him to pin them down and..."

Y/n : "Kelly, are you trying to get me killed"

Y/n's eyes widen as he saw Koneko and Kuroka holding a knife

Y/n : "what's with the knife"

Koneko : "Y/n what she said isn't true...right"

Y/n : "help me"

Small Timeskip

Blue team was laughing as they just saw Y/n's sister try and kill him, only when he told them he didn't do anything with anyone they calmed down

Kuroka : "good then"

Y/n : "why do you care if I've slept with someone or not"

Both girls blushed but no one noticed

Kuroka : "as your sisters we need to give you the go ahead on any girl you may want to date"

Y/n : "what kind of bullshit is that"

Everyone laughed while the girls scalded Y/n
