Eating breakfast outside a café Y/n was talking to Wendy and the others when he heard people chatting.

Guy : "hey did you hear about Royal Biblia Academy"

Girl : "no what about it"

Guy : "apparently there's an attack going on at the school, a group of students are holding the attacker off and people say they saw a dragon there as well"

Natsu(mind) : "Y/n"

Y/n : "yeah I already know....lets go"

3rd Person P.O.V

Currently at Royal Biblia Academy there was 2 separate battles going on, the first was Mira, Akio, Revi and Lugh they had to face a dragon also known as code D, meanwhile the others what to face someone named The White Demon Lord, Last Trinity.

As they battles went on Mira, Akio, Revi and Lugh managed to defeat the dragon and join the others in fighting the Last Trinity, after fighting for what felt like hours the group was at their limits.

Last Trinity : "well I'm impressed you've lasted this long but now I'm going to end this"

(L/T = Last Trinity)

L/T pointed a gun at the group ready to fire it as he did Tigia had got one of Y/n's guns that he left behind and fired it only for the gun to recoil and snap her wrist making her drop he gun and fall backwards. As she held her wrist in pain.

Y/n : "you know there's a reason I don't let anyone touch my guns"

Everyone turned to see Y/n standing there looking at Tigia.

Tigia : "where the hell where you...why did you leave us"

Y/n : "I'm sorry, I promise to exsplan everything to you I swear it but first"

Y/n picked up his gun before walking towards L/T as he did L/T fired his gun everyome looked shocked to see Y/n put his hand up.

Y/n : "Eihwaz"

As the bullet hit the shield it deflected up in the air before hitting the barrier The Last Trinity had placed. Everyone looked shocked as Y/n used an Thema like it was nothing.

Y/n : "you see I'm a reasonable guy...but when the one I care for get hurt...thats went I be come pissed off"

As Y/n made his way to The Last Trinity he kept slapping the shot fired at him with his hands.

Last Trinity : "no matter I'll just have to steal your power"

Y/n : "I've only used 100% of my demon heritage before but not once have I ever let my self go due to someone getting hurt....but for you I'll make an example of what happens when you pissed off a Sparda"

Everyone was in shock to see Y/n had completely changed.

As Y/n continued walking towards L/T he kept getting shot by L/T which would only bounch off him.

Y/n : "this is the part you run away"

Timeskip

Currently laying on the ground The Last Trinity had been beaten everyway thinkable, Y/n picked up the last trinity by the neck before driving the Sparda sword through him as he disappeared Y/n changed back and sighed he turned to see the group had shocked Looks on their faces....

Y/n : "so....yeah"

All : "WHAT THE HELL WAS THAT"

As they all questioned him Y/n saw Tigia walk to him with her head down.

Y/n : "Tigia I"

Y/n : "that was unnecessary"

Tigia : "pull a stunt like that again and I'll hit harder"

Arata : "wait how did you do that, what archive let's you change into that thing"

Y/n : "it's not an archive, that's what happens when I embrace my demon side I got from my dad it's called Sin Devil Trigger"

Arata : "damn I wish Sparda was my dad now"

Just then everyone heard clapping they all turned to see both Biblia and Liber walking to them.

Biblia : "that was quite the show you put on there"

Y/n : "you know I could kill both of you for almost getting them killed right"

Liber : "speaking of how did you use a Thema so easily"

Y/n sighed.

Y/n : "I left because my dad earned me that there's stronger people than I was and could hurt the ones I care for....so I left to become stronger"

Biblia : "but theres still a question...how much power did you obtain"

Y/n walked away from the group slightly.

Y/n : "well I mastered all the archives, I've even got multiple transformations, but I created a new one just for my self"

Everyone was shocked and in disbelief that he had learned all there was and even created something no one has seen.

Lugh : "I highly doubt that, given you have only be away for a few weeks no one could of master 1 let along all of them in that space of time"

Y/n smirked before everyone felt a powerful force push them back, they air around them felt heavy and even the sky turned completely red, just then everyone was in shock to see Y/n had changed but this one had a monster magic power like nothing they had ever felt before.

(TGS = Trinity God Sparda)

TGS : "this is my Trinity God Sparda Mode....so Believe me now"

Everyone nodded scared as they felt a monster power still after changing he smiled he looked at Biblia.

Y/n : "so this is it"

Biblia nodded which confused everyone.

Biblia : "yes I've already place your payment in your bags"

Mira : "wait what's going on"

Y/n : "my contract here is up....in other words the job is done so we're going home now"

Y/n looked at his home and sighed to see another contract.

Y/n : "I'll call Vergil to come and collect you guys I need to be going so yeah"

After kissing Yukikaze and Eclair and giving Kunou a hug he looked at Tigia and smirked but before he could say anything.

Tigia : "say one word and I will end you"

Y/n : "hehe ok fine....behave yourself my favourite Tsundere"

Tigia : "oh that's it"

Y/n quickly got on his bike and ride off

Tigia : "one day I'll kill him"

As everyone headed in side.

Biblia : "excuse me Yukikaze may I speak with you"

Yukikaze : "sure can I help you"

Biblia : "I was hoping to place another contract with zy/n but he left before I could"

Yukikaze : "oh what's that"

Biblia smirked......
