Rias POV

      I have been looking through every concievable book on ancient monsters that appeared long before mankind. I think I finally have a lead on one of the monsters when the tsunami warnings start blaring. I use a magic circle to get a higher vantage point and see a large wave coming towards shore. I quickly use the stongest barrier spell I've got to make a shield to protect the city, the wave hit and I can just barely keep the wave at bay. As soon as the wave subsides, I am joined by the rest of my peerage.

Akeno: Rias, are you alright?!

Rias: Yes, I'll be okay.

Issei: What do you think caused that wave?

Rias: I have a hunch, I just hope I'm wrong.

      We all then hear a rumbling sound from the water and see a giant lizard looking monster rise from the ocean and then roar.

Asia: Rias, what do we do?

Gasper: Koneko, I'm scared.

Akeno: Rias?

     After a moment of silence.

Rias: We fight. We first need to make sure no mortals will be harmed while we do this. Akeno.

     Akeno and I cast a spell that transports all of us and the monster to another dimension so we can go full power without humans getting in the way.

Rias: Asia, Gasper. Stay close to me. Rosweisse, Akeno hit it with everything you've got. Issei, give Gasper some blood, then hit it in the flanks with Koneko, Kiba, and Xenovia. Find any sort of weak point.

     Issei accesses his Balance Breaker and charges a fire shot and hits the monster in the face, giving the others time to flank it and hit it in it's sides. From those attacks, I could tell this monster was nowhere near (Y/n)'s level of power, I call for everyone's attention.

Rias: Keep me covered, I need 1 minute!

Akeno: You'll have it. Everyone hit and run, keep it's attention off of Rias!

Issei: Alright, let's kick some ass!

Everyone draws the monster's attention by hitting it then backing away to avoid a counterattack. I, meanwhile, am charging the most powerful spell I can muster, I concentrate and build up all of my magic power.

Rias: READY!

Akeno orders the team to move out of the way and I unleash my spell and hit the monster with everything I've got.

(A/N): Like this but a hundred times more powerful.

     The spell hits the monster creating a massive explosion, I drop to my knees and Asia comes to my aid.

Asia: Rias?! Are you alright?!

Rias: Yeah, that just took a lot more out of me than I'm used to.

     The dust clears and we can all see the monster dead on the ground.

Koneko: Do you think that was one of the monsters (Y/n) feared was coming?

Rias: Considering we were able to beat it, I highly doubt it. But I fear this is but a taste of what's to come. We need to continue training, no slacking from anyone, we need to be ready.

(A/N): Psych! I was just kidding this isn't the first monster haha! Seriously, if Zilla could be taken down by a bunch of jets, missiles and tanks, then there's no way that it could stand up to a bunch of devils. Have a good one guys, I have just narrowed down all of Godzilla's opponents and will be writing them out shortly. PEACE OUT!!!
