-3rd person POV-
(Gils wearing the outfit above)

We start this chapter seeing the Gremory peerage, the heaven trio, the Sitri peerage, and Azazel riding a train to the Gremory Domain in the Underworld. Well the Sitri and her peerage are going to the Sitri Domain but they are riding the Gremory train because Lobster is taking them there on the train.

Gil: "Why do I have to ride this when I have Vimana?"

Gilgamesh asked because he had to go on a train with mongrels, and Azazel to get to the underworld when he could just use Vimana.

Gabe: "I thought it would be nice to travel with other people for a change Gil, plus this is th eonly time we're going to be traveing on this train with them."

Gil: "*sigh* fine aslong as your right I'll stop complaining"

Gabe: "Thanks and where did Enkidu go? I know that she was sitting next to you a couple of minutes ago."

Gil: "She's over there playing a card game with the devil mongrels."

He answered Gabriels question, whil gesturing towards Enkidu with his hand that was holding his cup of wine that Gilgamesh is always drinking.

Gabe: "Oh, thanks. Enkidu always somehow manages to sneak off somewhere without me noticing."

Gil: "Your my master so it's natural that I answer your questions."

Gil replied while opening a golden portal and taking out a small vile of liquid and then proceded to open it. It smelled like (think of something from your childhood), he then poured the liquid into his cup of wine and before he drank it, put the vile which was slowly refilling itself back into GoB (Gates of Babylon) and turned to Gabriel and said

Gil:"Do not freakout after I drink this."

Gabe: "Why? What is it?"

she asked now kinda worried about what's going to happen.

Gil: "What'snabout to happen will change my personality, my appearance, and will make my stats go down a little, but trust me you'll love it."

Gabriel was now worried and exicted due to what Gil said. Gil then drank all the wine that was in the cup and set it down. He was then surrounded in a golden orb and no one could see inside of it. The glow brought the attention of everyone else in the room, Azazel was very intrigued and wanted to find out what was happening to Gil, Sona and her peerage were defensive bcause one the holy aura and two Gil was really strong and they didn't know what he was doing until the glow enveloped the whole room and when it faded everyone saw.

A child standing there

Kid Gil: ooh~ I'm guessing my adult form has ties with you people."

He said in a manor that was resembling a child. Enkidu sighed and shaked her head knowing what was about to happen. then in the next microsecond Kid Gil could be seen in the clutches of Gabriel, hugging him as if he was a teddy bear.

(Kid Gil = K Gil)

K Gil: "Oh~ hello master. Do you like my form?"

Gabe: "Yes, yes I do!" she said excited about this form.

The train stopped at a large domain, The Sitri Domain, much to the dissapointment of the girls in the peerage because they had to leave and that meant leaving the very very adorable Kid Gilgamesh in the hands of the Gremory peerage and Gabriel. But they did take a few pictures of him and by "a few" i mean a hundred or more photo's of him. Sona made a magic circle and her peerage stepped inside it instantly being teleported leaving a empty cirlce, Sona, Tsubaki, and Saji to say farewell to the Gremory peerage. well mainly Sona saying farewell while Tsubaki and Saji (who is female in this) take more pictures of the forever adorable child king of heros.

Sona: "*ahem* Thank you Rias for taking my peerage and I to my families domain."

Lobster: "your welcome, and it's what friends are for."

Sona: "Well then, we will see you at the meet up then."

Rias: "Yes, yes we will."

and with tha tthe Sitri's were off the train, but not before Tsubaki got one last photo of Gil. Then Gabriel and Azazel got a message that the Norse would be coming to talk about the Khoas Brigade. They then took Rias, Enkidu, and Kid Gil into another room to tell them.

(timeskip to after they talk)

Azael, the trio, and Rias cameback into the room and told them about the Norse coming. Then the train stopped over a large Domain shocking mosly everybody, with the people that were not affected by it were Enkidu and Kid Gil. And before anyone could say anything everyone was teleported, seperating the azazel rias and the heaven trio from the rest of Rias' peerage.

K Gil: "well let's just see if they can handle the overgrown lizard or will they crumble without their leader"

he said in a malicious voice which shocked Rias because of how malicious this "kid" was when he is like 12 -13 years old.
then a big red dragon landed infront of the kingless peerage.

Rias: "what makes you think they will fail to keep up with it, Issei's the red dragon emperor after all?"

K Gil: "I've already seen it happen using my clairvoyance noble phantasm. now i have the option of helping them so they aren't as badly damaged as i saw them or I can stay here and watch them be beaten brutally, now I prefer to watch them be beaten brutally. But the choice is yours Rias. Choose wisely."

while they were talking Akeno took control of the peerage to lead them but every attempt to damage or even stall the dragon was met with the dragon easily countering the attempt by either shooting fireballs or just brute strength. but when Issei boosted enough to think he could deal some damage to the dragon he charged the dragon but the dragon saw him coming and was about to shoot a fire ball at him but Kiba and Xenovia stopped him but they were pushed back fairly quickly and before issei could connect with the strike the five people watching the fight saw the dragon charging up a massive fireball thinking that the red dragon could definitly handle it. but the truth was the five knew he couldn't and he would be severouly damaged, so Rias did the smart thing and-

Rias: "save him please."

K Gil: "I'll be back."
(terminator reference)
and with that we see gil lifting a metal cap off his head standing right infront of issei.

and pushed Issei back out of the way of the fireball and summoned the Sheild of the Gods.
K Gil: "Hades's cap of invisibilty."

that shocked everybody even the dragon but not Enkidu.

Azazel: "ok Tannin thats all, and Gilgamesh how do you have Hades's Cap of Invisibility?"

Azazel asked wanting to know why Gil had a greek gods item and used it in the Underworld where said Greek God rules.

K Gil: "remember wen i said i have a prototype of every legendary item if i didn't actually own the original one?"

Azazel: "Yea-- Oh, now i get it. that Cap is a prototype of Hades's made in another universe, right?"

K Gil: "Correct."

after that Azazel then intoduced Tannin the former dragon king and that he is a devil and was ordered to see what they could handle and what they needed training in. and then Ddraig said he knew him then a whole new conversation was started, k Gil transformed into his adult self because he was bored of all the grown ups talking.

Tannin: "You do realize Tiamat's still after you and your host, and she's also in the Underworld too?"

at that moment Gil started having flash backs to the Tiamat of another universe, ad was sweating hard. Enkidu knows how strong Tiamat is also from that universe

Gil: "ah, question how strong would you say Tiamat is, in this universe?"

Tannin: "well if she's as strong as a Maou or a little bit stronger due to her being a dragon and all, shes the strongest of the five dragon kings, but I have to ask why did you want to know?"

Gil: "Oh well in all the other universes i've been in she would be even stronger and could indeed kill even me, i had to get help to put her down. because If I used full power EA it would destroy the universe. and she was able to block a fraction of EA's power and be completly fine."

now that shocked a lot of people minus Enkidu. mostly ddraig because if he was in those universes he would already be dead by how strong Tiamat is in those universes. (you know which universes I'm talking about, the Fate universes.)

Rias: "If we knew of the summoning ritual and the chant would she be summonable?"

Gil: "No, and even if it was the master would either have to be on par with me so they wouldn't die to the power output Tiamat gives off and when you summon a servant you get a fraction of their strength so if even if the Maous or anyone else in the three factions tried to summon her the power they would get would instantly kill them due to them not being able to hold and store that amount of power."

Rias: "then how was Gabriel able to summon you if the master of the servant gets some of the servants power."

Gil: "Tiamat in other universes is the literal enbodiment of choas and she has a lot of power but its still weaker than full power EA. but i already told you why I wouldn't use it at full power."

Rias: "Oh, that makes some sense, i guess."

Gil: "The other universes are confusing as hell, so you even being able to somewhat understand it is a good achievement. Now we should go."

Gil: "Issei your going to have the roughest training due to my kid self having to step in when Tannin wasn't going serious on you guys."

then Issei got scarred because training is hard for him
(Issei hella weak, press X to agree.)

----END----

This is all for today we aint getting the hot spring scene because one Gabriel is an angel and I don't want Gabriel being dirtied by the devils hot springs.

So next time we will possibly get to the training or the young devil meet up, and good news the F/GO summoning system is being added to this but i'm going to change it a little. becaue the Fate summoning process and what happens during it is kinda hard for me to understand. I know I'm small brain dont bully plz.

so farewell till next time.
