Both parents seeing their sons with their girls made them smile.

Gabriel is quite surprised that she doesn't sense nothing of lust or greed from them looking at the girls it is pure love that she's sensing.

Nami is quite surprised that (y/n) is not making a perverted look or anything which made her smile a little with a interest look.

Nico same thing but looking at issei remembered his words when she gave his younger twin her excalibur.

Now everyone look at the exit.

Twins: Let's go. Said in sync with determined look.

They prepare themselves for battle.

Then claire along with liddy and erica change to their battle uniform which made (y/n) blush a little.

Especially sona which made him face red and steam coming out.

Albion:{Damn partner you have the girls on the ropes for you.} Said in his mind.

Later.

They reach outside of the school and noticed the magic circle not far and magic tendrils going towards it.

Kokabiel: So you along with your angel wife and gabriel to face me. Said with a smirk.

They narrow their eyes with a serious look.

Angelica: Don't be to overconfident war monger it will be your downfall. Said with a serious look.

Then kokabiel snap his fingers summoned a big light spear and send it to the school gym destroying it leaving nothing but a giant crater.

Kokabiel: Well hope you can entertain me. Said with a smirk.

The girls a bit nervous to see what he did to the gym and both brothers stood their ground but still a bit nervous.

Ddraig:[Calm down both of you he's trying to put you two nervous and out of focus.] Said through their minds.

Albion:{Yes that's what he always do show off his power and make his enemies nervous to strike without thinking.} Said through their minds.

Both brothers took a deep in and out breaths to calm down and stay focused on the fight.

Kokabiel: Since you all came all this way for for fight then let's see you can handle my army and my pets. Said with a smirk.

Then a light appeared beneath his throne and shoot down to the ground which caused a hole to appear and fire coming out.

Y/N: Guess they are his forces. Said with a serious look.

Rias: We can't handle them while dealing with cerberus. Said with a worried look.

Both brothers look at each other and nod which both of them raised their arms up and a small magic circle appeared above it calling to their partners.

Sona knows (y/n) along with his brother can handle the enemy who follows kokabiel but worried if he fights the warmonger.

Sona 'thought': Please be careful my love. Said in her mind with a worried look.

Tsubaki right beside her noticed her worried expression well she isn't the only one worried for the white dragon emperor.

Then suddenly kuroka widen her eyes when her ears twitch and quickly turn around.

Kuroka: Heads up we got company heading this way. Said with a serious look.

They noticed the sky changing in multiple colors meaning the enemy forces of kokabiel are coming.

Sona: We can't fight while holding the barrier. Said with a concern look.

Kuroka: You and your peerage keep the barrier up we got you covered. Said with a serious look.

Both parents went close to her while watching the smoke cloud where kokabiel is.

Angelica: Impressive as always gabriel. Said with a small smile.

Which she look at her for a moment and back at the smoke staying focused on the fight.

But unknown to them she did make a very small smile being praise by her sister just like back then.

The smoke clears to see kokabiel cloak a bit torn while smirking at them.

Kokabiel: This is really interesting, never imagined the left hand of god and lucifers right hand fighting together. Said with a smirk.

Angelica: Don't think you have a chance. Said with a serious look.

Kokabiel: Oh on the contrary I was hoping to face you two again after my defeat back then. Said with a smirk.

Devolos: Oh yeah I haven't forgotten those time you sneak in to attack devil territory where civilians are. Said with a serious look.

Angelica: And sneaking to attack heaven as well. Said with a serious look.

Which he got a little mad at that reminder because it's true he tried to attack while their leaders are occupied on the front lines but didn't count on devolos and angelica who stayed at their territory to protect their homeland.

Kokabiel: If you two been on the front lines back then the fallen angels would have won the war. Said with a serious look.

Devolos: From the beginning I never cared about the war, only to protect my kind for incoming forces that will sneak in. Said with a serious look.

Angelica: I did the same to protect heaven for incoming forces until the heavenly dragons started to fight each other. Said with a serious look.

This got gabriel surprise to hear from them sure back then during the war her sister stayed in heaven to protect it which earned her position as god left hand.

But to hear that from devolos who is a devil only cared to protect his kind from threats, hearing what he said made her wonder more about him and how angelica fell in love with that man.

Gabriel will save it for later because she sees kokabiels aura flaring.

Kokabiel: I'll make sure to have vengeance for my humility defeat. Said with a smirk.

Down on the battle both brothers pushed the enemy back this got the girls to move in to support them.

In a distance asia along with yubelluna, xuelan, scarlet and erica looking at the battle seeing everyone doing their best.

Asia couldn't help but worry seeing her lover and friends fighting to prevent a war which she hope they can win.

Then erica noticed her worried and place a hand on her shoulder gaining asia's attention.

Erica: Don't worry asia they will be fine as long they work together. Said with a smile.

She nod of understanding but couldn't help but worry.

Then scarlet noticed something and got in front of them.

Scarlet: Heads up they noticed us. Said with a serious look.

They look to see some stray exorcists running towards them.

Yubelluna: Erica, xuelan both of you stay close to asia. Said with a serious look.

Both of them got in position and erica summons her weapon ready for anything.

Then scarlet summons her armament ready to fire.

Scarlet: I know that we must prevent some collateral damage but knowing these bastard don't care about it, I'll apologize sona after this. Said with a serious look.

Then she shoots multiple missiles heading to the enemy hitting them with an explosion.

Yubelluna noticed some coming out and shoot her fire bomb attack at them hitting them on impact.

Yubelluna: You and me both will apologize to lady sona after this. Said with a serious look.

Both bakugans look at each other.

Lumagrowl: Two down. Said with a grin.

Shadowgrowl: Four more to go. Said with a grin.

Then they noticed the first two of them get back up and look at them.

They growl at each other but noticed some of their targets close by and went after them instead.

Both bakugans widen their eyes and quickly went after them.

Shadowgrowl: That one is heading for asia and the others. Said with a concern look.

Lumagrowl: The other heading for (y/n). Said with a worried look.

Then yumi landed in front of asia.

(Y/N) dealt with the fallen and noticed the guard dog impaled which knows that yumi is here and sees her with asia.

Y/N: Your alright. Said with a smile.

Rias noticed yumi and smile to see she's fine and then hit eight more enemies with her power of destruction.

Asia: Thank you yumi. Said with a smile.

She nodded with a smile and went to join in the battle.

Shadowgrowl appeared in front of the impaled while his aura flaring.

Shadowgrowl: Say goodbye mutt, Abyss doom stream. Said with a serious look.

He shoot his purple beam attack destroying cerberus roaring in pain and disappeared.

Issei just got the enemy and then noticed rias along with akeno getting surrounded.

Issei: Ddraig. Said with a serious look.

Then he jumps in the air and aims at rias and akeno.

He just smirk.

Kokabiel: Never. Said with a smirk.

This got them to be on guard.

They suddenly disappeared and reappeared in front of kokabiel to strike him with their swords but he quickly blocks them with his own light swords.

Once more they vanished which clash in all directions making everyone almost hard to see how fast they move except for devolos, angelica and gabriel.

Gabriel: How can this be the dark side of excalibur to manifest?. Said with a surprise look.

Angelica: I think it's because both issei and (y/n) are twins but different magical properties whicb is why the sword manifest, light and darkness working together. Said with a surprise look.
