Disclaimer: Guilty Crown belongs to Tetsuro Araki, Production IG and Funimation. Final Fantasy XV belongs to Square Enix, Tetsuya Nomura and Hajime Tabata.

A/N: So here is another one-shot crossovering Guilty Crown with the long awaited video game, Final Fantasy XV (formerly Versus XIII).

This is the game that was first announce back in 2006, formerly part of the Fabula Nova Crystallis project, before everything changes for these games. I remember those days with all those Noctis fanart and stuff such as he and Lightning meet many times (and as a fan-couple). With the E3 2013 announcement and the demo finally playable, FFXV will be one of these games that'll renew Square Enix's esteem. It also gives our fandom more maturity compare to our teenage years (at the time when Advent Children, FFXIII and Dissidia were released). FFXV will be a huge game changer to Japanese role-playing games to the point it feels like Skyrim.

Crossovering with Guilty Crown should be interesting because I and someone once attempt to do a co-author Kingdom Hearts one since it's done by Nomura, but it's discontinued. Both series have a theme of heirs to the throne. If you expect Shu and Inori to appear, then you're mistaken.

Originally I was going to have this as one story, but I decide to split it to two parts due to being busy at college (well a semester is over and I gotta worry about summer). Let's enjoy reading this.


"There is nothing either good or bad, but thinking makes it so."

-William Shakespeare, Hamlet


Forest/Universe: FFXV

This is a fantasy world with elements of realism. It is something that feels more human rather than the blend of fantasy and science fiction.

Upon the news headline, the people mention about a civil war between two crime families: the Kingdom of Lucis and the Empire of Niflheim. In real-life, it reminds the movie fandom of The Godfather.

On the other hand, nature ignores human society. The vast forest gives an emerald vibe to this calm location. A river is heard streaming the clear waters with fish swimming. The grass remains light green as ever, as there are small fauna such as mice and lizards are seen.

Somewhere on top of a tree branch, a majestic bald eagle is seen about to fly off to the mysterious skies.

A skirmish adventure begins.


(Cue Somnus - Final Fantasy XV)


Episode Duscae: Versus Quest


Gas Station/Inside

It begins inside a gas station, to which it's located at the outskirts of the road. What it means is that the roads are where cars are driven for people to go on roadtrips or going to a destined place.

Four young men wearing designed black outfits are seen sitting in a round table, in which they are seen as childhood friends.

One has spiky black hair with a hairstyle that looks like a familiar Uchiha character and blue eyes with a black glove on his left hand, his name is Noctis Lucis Caelum.

Another is a tall man with dark brown hair straights to his back, amber eyes, jaw beard, and a long scar on his left eye, he is Gladiolus Amicitia.

Next is a man with short light brown hair in front of his hairline and green eyes, he is Ignis Stupeo Scientia who is the advisor to Prince Noctis.

Lastly is a young man with blue eyes, light freckles, and unruly blond hair named Prompto Argentum.

They are seen in a relaxing mood since their car needs to get fix. While Noctis and Gladiolus are casually sitting to let time go by, Ignis is holding some kind of a wanted poster.

Prompto is taking a peek at the poster, which reveals to be a picture of a bull-like monster with a scarred eye and a missing horn, "Ah, so we're going to hunt that Behemoth, right?"

"Yes, the Dread Behemoth's name is Deadeye." Ignis sighed while explaining, "This monster is rumor to be feared in this designated area."

"That's why once we think of something to kill it, we can get 25,000 gil enough to pay the repairs. Can't wait longer than never." Prompto smiled playfully.

"Look, we have yet to come up a strategy to tackle that Behemoth." Gladiolus warned the young man.

"As much as I hate it, he has a point there." Noctis agreed with his cool-minded tone.

"Not to mention keeping our highness in safety." Ignis added in concern about the prince.

Noctis respond to Ignis with a deadpan tone, "You know most of us can fend for ourselves even if we stick together."

"Yes, but it's just to reassure your chances to reclaim the family throne." Ignis said to Noctis.

Prompto puts his hands in the back of his head and groans, "It's such a bore!"

"Just hang in there." Gladiolus muttered.

Before they can talk more, the group notices a couple near the counter ordering something. One is a young man with long blond hair, blue eyes, a black mercenary uniform with a red middle strip and small coffin insignia on the left side. The other is a young woman with long pink hair, reddish orange eyes, a black dress, and barefoot.

That is strange, Noctis and his friends wonder of who these two are. Are they travelers or something? Nevertheless, the prince decides to get off his chair and begins to approach the couple.

The mysterious couple turns to see Noctis.

The blond-haired man begins to speak up. "Who are you?"

Noctis sighs and firmly answers to the stranger, "Me and my friends are wondering the same thing."

The pink-haired girl takes notice and simply gives a smile, "Aw, you don't have to feel modest about it."

"No, it's not like that." Noctis muttered to the cheerful girl in being embarrased. Ignis then stands up and steps in the conversation.

"Forgive our highness' shyness, allow me to do the introductions." The glassed man requested.

"Go on." The blond-haired man stated.

Ignis clears his throat and greets, "My name is Ignis. Our highness here is Noctis, the other two companions are Gladiolus and Prompto."

"So that means you're a prince?" The blond-haired stranger asked Noctis.

"Well, yeah I am." Noctis answered about his family lineage, "But I was still wondering about your names?"

After a few seconds, the mysterious couple decides to respond to the prince's question.

"Tsutsugami Gai." The blond-haired man stated.

"And my name is Ouma Mana." The pink-haired woman added about her identity.

"Wait, your surnames seem to be foreign." Noctis commented and wonder. "Does that mean you two are from somewhere far away?"

Gai then honestly answers, "Well, all I can say is that we're not in this world."

This gives a slight surprise to Noctis and his friends. Especially with the outfits and the presence that Gai and Mana caught their attention.

"Does this mean that you come here due to the Goddess of Death?" Ignis questioned Gai and Mana, he is talking about the goddess in their home dimension named, Etro.

"Hmm, let's just keep this one a secret. We're just travelers." Gai replied to him.

Mana then sees the wanted poster in Ignis' hand and points to it, "Oooh, what is that you're holding?"

Ignis looks at the Behemoth poster and turns to Mana, "This is a poster of a monster we are planning to kill."

"And that's the Behemoth he's talking about!" Prompto positively cried out, much to Gai and Mana take notice of the beast's name.

"Quiet, Prompto. We don't want them to get involve." Ignis chastised the younger man.

"Actually, this creature is taking our interest." Gai pondered about the group's mission.

Gladiolus gives a darkly stare at the light-hearted Prompto while Noctis facepalms of this self-act. Noctis' group is concern of their trust towards Gai and Mana to wonder if they really capable of fighting like themselves.

"So that means you are coming with us?" Noctis asked the two.

"Yep, me and Triton can help getting rid of that dirty, meanie beast." Mana smiled while giving a slight joke.

Prompto chuckles at the compliment, "Hehe, this girl digs my style."

"Maybe I can show you my skills to prove my worth." Gai offered.

"Hmm, perhaps we can let you assist us for a bit." Ignis made his decision to the blond-haired man.

"We better let Cidney know first." Noctis reminded his friends alongside the two guests.

With the rest of the party members nod at the black-haired prince, they are going to head outside for the side-quest.


Gas Station/Outside

Outside of the gas station area, a few random civilians are seen either filling up their automobiles, or just simply resting like Noctis' group. Speaking of them alongside their two guests, they meet the person Noctis has mentioned.

A spunky young woman is seen with short curly hair, olive green eyes, wearing a red cap with yellow outlines and a logo, wears a yellow jacket, that reveals her stomach and an orange bikini top with deep décolletage, wears jeans shorts with a brown belt hanging around her hips, thigh-high black stockings, white high boots on heels, and brown gloves.

Her name is Cidney, to which she speaks with a southern accent, "Hey! So y'all heading to the outdoors?"

"Yeah. We're ready to find that Behemoth to have enough gils." Gladiolus answered.

"And we'll do our best to succeed with some new allies." Noctis said about Gai and Mana.

Cidney walks towards the guests and stares at Gai for a bit to examine, then to Mana before backing off a bit.

"You folks have some strange people." Cidney commented about the two.

"Hey, I'm already weird myself as it is." Mana responded to the female mechanic's words.

"We're just supporting them so long as we don't get in the way." Gai honestly said to Cidney.

"You best take care of your girlfriend here as well, you hear?" Cidney grins at Gai.

Gai stoically wonders a bit, but Mana holds her beloved Triton's hand in letting him know that they'll stick to one another.

"Alright, then we're heading off." Noctis announced to the group.

"I'll lead the way, your highness." Ignis offered to lead everyone into the outskirts.

With that said alongside Cidney waving for her farewells, the group ventures to go outside for few reasons: to gain some experiences and for to hunt down the Behemoth named Deadeye. At the same time, they are waiting for their car to get fixed by tomorrow once they have enough money.


Outside/Fields

(Cue The Elder Scrolls V: Skyrim OST - The Gathering Storm)

At the vast plain area that is filled with light green grass, the sun remains bright as ever with some clouds. At a lake, two gigantic Sauropod-like monsters with heads that look like a cross between a bull and a boar are seen grazing peacefully. Their names are the Catoblepas.

Then, the audio of the grass is feeling slight footsteps, suddenly gets a bit louder coming from the humans.

Across the fields are six figures wandering as one party: Noctis Lucis Caelum, Gladiolus Amicitia, Ignis Stupeo Scientia, Prompto Argentum, Tsutsugami Gai, and Ouma Mana. Of course Mana is the only girl of the group.

After a few moments, Ignis stops and halts the group in advance.

"What is it?" Noctis asked the glassed man.

Ignis turns to Noctis and answers, "Well, I believe we should gives some training to Tsutsugami Gai and Ouma Mana."

"Training huh?" Gai raises an eyebrow in his curiosity.

"Yeah, maybe Noct should spare with you to see what you're capable off." Gladiolus commented.

Noctis recalls the times of his training session with his childhood friends, to which it pays off well in real combat.

"I'll accept the challenge." Gai responded and conclude, "But I won't fight with a 'weapon' yet, just my prowl instinct."

"You seem to be confident." Noctis muttered about the blond haired man's decision.

(End Theme)

Then, Prompto is seen advancing to Mana and smiles at the pink-haired girl.

"Hey there, how about we can watch the scene together?" Prompto asked somewhat trying to be nice.

However, Mana gives a playful smirk and ignores the blond-haired man. "Sorry bug, you know I'm taken."

This leaves Prompto slightly disheartened in a humorous matter. At the same time, Noctis and Gai are beginning to face each other in different sides. Noctis is wielding a standard sword called the Avenger.

(Cue Final Fantasy XV: Episode Duscae - Daytime Battle Theme)

Their audience is watching the training.

And then it begins. Noctis charges at the unarmed Gai with his sword, only for Gai to dodge on the right side and delivers a quick kick at Noctis. The black-haired prince sees it come and jumps away a bit.

Noctis then switches weapons to holding a Wyvern Lance, in which he does a Dragoon Jump and is lunging at Gai at the next turn. However, Gai's keen senses see it coming and evade the lance.

"I bet you're a trained person for a challenge." Noctis commented.

"Heh, and I thought your holding back." Gai smirked.

"We'll see about that." Noctis responded to Gai's taunt as he switches weapons to a great sword called the Zweihander, known in German as the 'two-hander' sword.

Noctis cries out and attempts to attack Gai by doing a few slashes, but Gai evades the blade each time. The black-haired prince delivers another one, only which Gai uses his bare hands to block and hold the Zweihander!

"Remarkable." Ignis said in slight amazement while fixating his glasses.

"How in blazes did he do that?!" Prompto cried out in wondering.

"Tehehe, Triton is Triton in pulling off his strength." Mana gives a taunting, yet light-hearted smile at Prompto.

Once Gai gets a hold of the great sword much to Noctis' brief surprise, he pushes back and delivers a swift punch at Noctis' face. Noctis backs off before having his weapon disappear.

(End Theme)

After the spare training is over, Gai and Noctis are given potions by Ignis to heal themselves. Gai and Mana notice that these potions are a sort of healing item during a traveler's journey.

"That's some nice reflexes you're having there." Noctis said to Gai.

"Gotta hand it too you, your not half bad." Gladiolus added to the results.

Gai can only give a coolly smile to the two young men with his arms cross while closing his eyes. Mana walks to stand by her beloved's side. This is indeed the chance in gaining Noctis and his friends' trust.


Thirty minutes after the sparing match, a great marsh is seen with mud covering much of the ground. The travelling party continues walking since Gai's sparing with the prince of the Lucis kingdom. Just then, they come across something surprising.

"Whoa guys, check it out!" Prompto cried out while pointing at something on the muddy ground.

The blond-haired man is right to get his friends attention. They see a large footprint that feels similar to a giant monster leaving a mark after rampaging a nearby town.

"It's so gigantic!" Mana blinks while staring at the the large footprint.

Gai coldly stares at the footprint with his arms cross and state, "So this is the sign of the monster you're looking for?"

"Indeed, Deadeye the Behemoth is a menace between these territories." Ignis answered to Gai. "We seem to find the first clues in tracking down the beast."

"Well, I'm not afraid of that beastie." Mana commented.

"I think you honestly are for a girl." Prompto joked.

"Please don't make fun of me being the only one with an all men-cast." Mana joked back at the blond-haired gunner.

Just then, the group hears some low bellows and wolf-like growls. There are two kinds of monsters. The first group looks like slender brownish-gray wolves with reptilian teeth called Sabertusks. The second group are large mammoth-like creatures with brown wooly fur and light gray faces called Garulas. The monsters turn their attention to the party.

"Guess we got company." Gladiolus muttered.

"Alright, about time to … for once!" Prompto smiled while ready his firearm.

Noctis turns to Gai, "Are you ready for change?"

"Yeah, I'm always like that." Gai nodded at the prince for a real battle.

(Cue Final Fantasy XV: Episode Duscae - Daytime Battle Theme)

The party group charges at the Sabertusks and the Garulas with their weapons and begin to hack and slash them with Mana supporting the young men by conjuring crystal powers much to the surprise of Noctis' group. Speaking of Mana, her 'innocent' voice fills in the scenery while the battle noises are heard in the background.

"Hi everyone, this is Ouma Mana speaking! I have a great time with Triton and these boyfriends. Well, that blond-haired guy with the gun did attempt to woohoo me over, but I rejected him. This Noctis person reminds me of my little brother who I once fell in love in the past, don't blame me, blame that rock back in our home dimension. He is some kind of a prince of my dreams, but I digress. Okay, why the heck am I mumble random stuff while I help out the men against these filthy beasts? We're almost done cleaning the mess."

Eventually, Noctis and his cohorts finish off the last remaining beasts before finding a safe passage at the end. They immediately ran towards that path. One battle to get some exercise is good for them, to which Gai and Mana have this experience.

(End Theme)


A/N: It's interesting that Gai Tsutsugami and Mana Ouma are the main guests instead of Shu and Inori that some readers expecting. Granted since their deaths, these versions of them are given the opportunity to become watchers of other dimensions, starting with their interaction with Noctis and his friends.

Apologize of Mana's monologue at the end instead of showing the full wild battle alongside the spare between Gai and Noctis is short because again, time constraints and school, but it doesn't matter either way.

See you in the second half which will complete this one-shot.
