Previously:

The leviathan takes a few steps back before running as fast as it can and rams into the mech sending its main body and legs back into the cliff leaving its arms still wrapped up by the Sea Feilong. The leviathan charges up a beam attack to finish off whoever is piloting the mech but that's where I come in to interfere.

"Everybody get off and spread out to distract them as best you can!" I shout.

And following my command, everybody got off quickly and started shooting their various weapons towards the leviathans. Once it was only me on top of Ker, he jumps off the cliff as I pump my mana into him causing him to grow 10 times his size like before which makes him only slightly smaller than the leviathan that it's almost not noticeable.

Without stopping as the leviathan is still charging up its beam, Ker uses the force from his run to bite into the neck of the leviathan causing it to loose balance and fall into the sea prompting Ker to sink his claws into its body, pinning it to the sea floor. Before he could bite its head off a Sea Feilong is quickly approaching from our right while the other one is getting distracted by multiple dust powered rounds.

Ker quickly jumps back, narrowly missing the Sea Feilong's bite as it goes re-enters the sea. We stay on guard with Ker focusing on the leviathan and I'm keeping watch for the Sea Feilong. The leviathan gets up and with a pained roar, runs at us again. It goes for a swipe which Ker easily dodges despite his size before retaliating with a head but to its head causing it to stagger back.

Ker was about to charge but the Sea Feilong soared up into the air behind the staggered leviathan with a beam already charged up in its mouth. It fires and Ker quickly runs around the leviathan as the beam is following only a few giant-sized steps behind us. A few seconds later and it dissipates as the Sea Feilong drops back down into the sea. That whole time of Ker avoiding the beam was enough for the leviathan to mostly recover before it tries to charge at us again.

But that was unsuccessful as Ker's tentacles emerge from under it and wraps around its limbs, holding it in place. Ker charges at it after ducking under another attack of the Sea Feilong. He bites down on the creature's already damaged neck and proceeds to rip out a large amount of its flesh right from its neck. It tries to roar but the air only comes out through the gaping hole in its neck. Ker quickly kills it by biting it from the back and mimic what he did before by ripping out a large amount of flesh. Now it's a clear view from one side to the other before Ker swipes its claws at the already thinning portions of its neck left that's barely keeping its head up.

Its head promptly falls off already turning to black smoke before getting absorbed by Ker. Before it even reaches the water it's already been absorbed with its body quickly dissolving into smoke as well. The Sea Feilong quickly pounces from behind us and I can already feel Ker preparing to use his tentacles. But suddenly, just as he's about to use them, loud metallic thumps can be heard and it turned out to be the mech that I thought was disabled.

It intercepted the Sea Feilong's attack by jumping before hitting its face with its knee, sending the Sea Feilong back into the Sea yet again.

'Kratos, Erebus said that they're running low on their ammo and won't be able to distract the other Sea Feilong much longer'

'Tell them to stop, we just needed them to stall so we could kill that leviathan'

'Alright, relaying your message.'

And not a few seconds later the group stopped firing at their Sea Feilong, and it quickly goes to the aid of the one we're fighting. I look at the one that's piloting the mech and it seems to be an old woman to be piloting it with a proper looking uniform on. I gesture her to stay back, and I can see her visibly get mad and is about to protest when both of the Sea Feilong jump up from both our sides.

We react quickly as Ker sidesteps the initial attack before biting down on its neck like he always does. It tries to wrap its serpentine like body around Ker to try and do some damage to him, but Ker just increased his strength before a loud crunch could be heard. The creature slowly stops wriggling and goes limp before getting quickly absorbed.

We look over to how the armless mech was doing and it was doing alright with only having kicks available to be a viable source of damage. That was until the creature wrapped around the mech from its legs up to where the pilot is. It brings its head back to strike at the protective glass but Ker intervenes before it can go that far.

He jumps in while hooking the creature's neck by his claw as he falls while bringing the head with him. It tries to resist by trying to use the mech as a support to stop it but that only served to deepen the claw that's already in its neck and make it shred its insides. It lets go due to the pain before it quickly gets its head crushed by Ker.

After it got absorbed by Ker, I see that the mech pilot still looks ready to fight Ker. Even if she saw what he did to the leviathans, and that she would be no match for him, she still looked determined to fight to her death it seemed.

Ker takes a step toward our group and the mech takes a step towards us. We take two steps and it follows. And soon after, Ker ran straight at our group with the mech chasing us and is slowly getting farther away as Ker is quite fast even at this size. We make it back to the others as Ker shrinks while he jumps. We land right when Ker makes it back to his normal size and we look back to see that the mech is still fast approaching.

"Do any of you know who might be piloting that mech?" I ask.

"I think it might be that Cordovin lady that Maria was arguing with when we were at the military base, because I think I remember Maria talking something about her having a mech." Oscar says.

"Then if we want a chance to actually get to Atlas legally, I think we should see what she has to say." Ruby says.

"I'm with Ruby on this one." Blake says.

Everybody else agrees before Raven asks me, "Hey Dominus, what did you do to increase Ker's size?"

"I gave him my mana which allows him to grow to the size he was. I found that out during Jinn's whole spiel because there wasn't anything to do other than listen to her." I say making the ones who were there when Jinn did her whole thing flinch, don't tell me...

"Wait, who's Jinn?" Jaune asks.

"… We'll uh… tell you when we get back." Qrow says awkwardly.

"Really?" Raven deadpans, "You haven't told them yet? *groan*Now I'll have to deal with their reactions when we get back."

"What?" Ruby shouts, "Don't look at me like that, we just didn't have the right moment to tell them that's all!"

"Not to be rude, but in case you forgot, we have a giant mech headed right for us." Weiss reminds them.

And said mech has just stopped in front of us as the pilot who I now assume to be Cordovin looks down at us but probably at me specifically before speaking through her speaker, "State your name, and purpose of being here."

"I hope she realizes that she won't be able to hear me behind that glass while she's all the way up there." I say

When I didn't start talking and just stared at her she likely realized the problem before my scroll -who I gave to Raven before Ker jumped off the cliff- started to vibrate. Raven gave it to me and I answered the call.

"Now that you can hear me, I'll say this again. State your name, and purpose of being here." She says through the scroll instead of the speaker this time.

"My name is Dominus, I'm a hunter and I'm here to escort this group I'm with." I reply.

"While I appreciate the help with the leviathans, that doesn't mean I'll trust you. And I'm sure you can figure out why." She says.

"Would the word of the Schnee heiress be enough to convince you?" Weiss speaks up.

"Only slightly Ms. Schnee. I'm afraid that I can't let someone who can seemingly control grimm go just like that. I'll have to do a thorough interrogation to even give him an ounce of trust." She says.

"And I assume your not going to do that here and now?" I ask.

"Obviously not, you're coming with me back to the base or you will be arrested." She says trying to sound threatening.

"I doubt you'll have anything that I can't break out of." I say.

"Whether that's true or not, you'll come back with me one way or another." She says.

"Why don't you just go and get it over with, the quicker we can get this done, then the quicker I can kill that son of a bitch who took my daughter." Raven says.

"Fine then." I say before Ker flies me up onto the top of the mech as it begins its walk back to the base.
