Highschool DxD : The Lost Brother

Chapter 1 : Legend's, Legend's Never Die

Currently standing in front of a grave stood 2 girls, 1 of the girls had long black hair with split bags, she had Hazel-gold eyes with cat like pupils her name was Kuroka Toujou and standing beside her was her younger sister Koneko Toujou, she had white hair with 2 bags going past her shoulders and several loose ones she also has Hazel eyes, they both had a bunch of flowers in their eyes as they stood in front of the grave which said

Y/n Toujou

Died protecting his sisters, and will never be forgotten

As the girls put the flowers in front of the grave they held each other as they began crying

Koneko : "I..I miss him"

Kuroka : "I know you do Shirone, I do as well but he gave his life for us, the best thing we could do Is live for him and who knows he could be in a better place now"

Elsewhere

Y/n : "did someone drink the last Hetap, I'll kill you"

Back with the sisters

After saying their goodbyes they leave and head back to the Hyoudou residence, but what they did know was a group of covenant had just arrived and they decided to take earth for them self's....

Elsewhere

Currently eating lunch is Blue Team, as they did all the recruits couldn't help but look at them, after all the legends and story's they heard about the group, Blue team is considered legendary but the team ignored all of them and chatted among each other, just then

intercom : "could blue team please report to the captains office, I repeat blue team please report to the captains office"

Timeskip

Blue Team is currently standing in front of the captains desk

Y/n : "Sir you called for us"

Captain : "yes theres reports of the covenant attacking a planet of humans, I want you and your team to go there and stop the threat"

Y/n : "yes sir"

After leaving they grabbed their gear and got to a ship that was ready to take them there, as they boarded and sat down Y/n took a photo out it showed Y/n when he was younger standing beside his sisters, as he looked at it blue team couldn't help but smile at the sight, they know about Y/n not being human and how much he wants to see his sisters again, as they looked on

Pilot : "Blue Team we're above the targeted area, you'll have to jump"

Y/n : "ok so for the looks of things there seems to be 3 small groups fight the covenant separately and 1 large group fight the main force"

Kelly : "what's the plan"

Y/n : "we take the smaller groups of covenant out with stealth, and by my guess the groups down there are supernatural like me so we won't have to worry to much about protecting them, after the smaller groups have been dealt with we'll launch a full assault on the main force and wait until the air strikes take care of the rest of them"

All of the teams nods and the hatch openes

Y/n : "let's go kick some covenant ass"

3rd Person P.O.V

Sona's Peerage

Saji : "what are these things"

Sona : "I don't know but we have been given instructions by Sirzechs to hold them back as much as possible"

As the fight went on they started to become tired

Tusbaki : "S..Sona I don't know if we can keep this up for much longer there's to many of them"

Sona's eyes widen as her Knight Bennia was fighting of the covenant but she didn't see the one behind her

Sona : "BENNIA LOOK OUT"

Bennie turned to see a energy sword about to be brought down on her, she closed her eyes...but nothing happened when she reopened them her eyes widen as she saw a blade that looked the same as the ones the covenant were using go right through her attackers chest, the sword they when up and cut the covenant in half just then everyone stopped and thier eyes widen as they saw someone standing there in white Armor while Sona and her peerage looked confused the covenant looked afraid and Sona spotted this

Sona(mind) : "their scared of it, just what is that thing"

Just then the armoured figure spoke only 2 words

??? : "Kill Them"

Just then Sona and her peerage looked scared as the covenant they were fighting suddenly dropped dead infront of them

Timeskip

After saving the smaller groups they would run back and join the main forse

Sirzechs : "Sona, Sairaorg, Riser what are you doing here, you're meant to kill the ones in back"

Sona : "that's just it they are already dead"

Rias : "you killed them all"

Sona : "no a group of people in Armor showed up and killed them"

Sairaorg : "so it happened to you both as well"

Riser : "Riser didn't need their help in the first place"

Azazel : "where are they now"

Sona : "I don't know they disappeared when they were done killing them all"

Serafall : "I've never heard of Devils that look like that"

Azael : "same with the fallen"

Michael : "I have to agree no angle matches the description"

Sirzechs : "Well we will find them later but for now join the battle"

After a while everyone was starting to become more tired, as the battle went on Blue team watched but as they did Y/n's eyes widen as they landed on a pair of girls fighting beside each other

Y/n : "no it can't be"

Frederick : "Y/n you ok"

Y/n : "I..i think I see my sisters out there"

The rest of blue team looked at Y/n

Linda : "you sure"

Just then Y/n saw a covenant go and try to kill Kuroka and this pissed him off

3rd Person P.O.V

Bang

Everyone looked to see an elite that was behind Koneko and Kuroka had its head blown clean off, everyone looked and saw the same group that took out the covenant from bafore walking to the middle of the battle field as they did all eyes were on them, the group couldn't belive what they were seeing one moment the ailen race that attacked them are not afraid of them, then the next a group of 5 people show up and the aliens look terrified, just then what shocked them even more was that the white one ran in and started killing anything that moved after about half was killed the rest join in in what took no less that 20 minutes the group of 5 slaughter everyone of the covenant like they were made of paper...

Timeskip

After Blue team were done bodies laid everywhere, just then Sirzechs had to think quickly, after seeing this display of power and team work this group could kill them

As they were about to moved to them they hear the white one talk to someone

??? : "sir mission Is complete requesting e-vac"

Soon he turned to the rest of the group

??? "eta 5 minutes for e-vac"

Sirzechs decided to make his move

Sirzechs : "um excuse me"

Y/n turned around to see the group approach them, but soon saw the faces of shock as they stood in front of them, blue team stood tall about the rest of them, he could tell they were intimated by the size of them

Y/n : "can we help you"

Sirzechs : "who are you people"

Y/n : "we...are Spartans..."
