Gildarts: Good to see that you're alright, Son in law.
Neos: Don't call me that. To think using your magic to enlarge the crack so the other can follow me.

As Neos try to move he stumbled on his feet, after going to that world the only rest he have is the 10 minutes that he pass out, before forcing himself back up.
Gildarts: Are you okay?
Mana: Nii-san, are you alright?
Neos: I'm fine, just...
He didn't say anything only stood there, not moving.

Porlyusica: Problem Child.
She hit him in the head with a stick.
Makarov: Please go easy on him, Granny.
Porlyusica: This Problem Child is going to be the dead of me.
Mana: Please don't say that.
Porlyusica: He have multiple broken bones, strain muscle, and even lost of blood. He should heal with time, make sure he doesn't move too much so his wound can heal.
Wendy: I can heal him.

Mira: Look like I won this one Neos.
She smile showing him a peace sign with a blue 1th ribbon on her other hand.
Erza: Of course you won, most if not all of your votes are male.
Mira: Unfortunate are we.
Erza: Everyone is literally stunned that he can sing that they forgot to vote.
Mira: But he only miss out on 1 vote, what a shame.
Visible spark can be seen as the two woman glare at each other.
Cana: I'm surprised you can sing.
Cana have her arms fold, having her arms on top his head as she lean on him, her chest again the back of his neck.
Neos: Of course I can, I found some magic weapons that have musical property. I wasn't going to enter until a Milk Monster let it slipped to Erza.
Mana sneeze while drinking her glass of milk almost dropping it.
Erza: You need to express your self more.
Mira: Before believing anyone, continue being What you're believed to be; nobody's perfect. So cool!
Levy: Where did you come up with those lyrics?
Neos: On my adventure.
Cana: Now I'm kinda curious. What interesting story do you have?
Neos: Well I guess I can share some.
Levy: You willing share a story on your adventure?
Cana: That's a first.
Neos: I got nothing better to do, if I get injury again so soon, Porlyusica will probably kill me. That mean I have to go to Takemi instead.
This gain all of their attention.
Two year ago
Mana: According to the map it should be here somewhere.
The little girl is sitting on top of her brother shoulder, in the small boat they riding. Striker a small boat made by Neos to help him travel around in sea.
Neos: It location said it should be around here somewhere.
Mana: I can see somekind of large magic energy over there.
She pointed up ahead.
Mana: Although it's under the water.
Neos: Probably where we need to be.
Neos feet erupted in flame as his boat began sailing towards the direction.
Natsu: Wait!? You have a boat that run like that!?
Neos: Yes, I call it Striker.
Wendy: You don't get motion sickness? I mean you didn't have physical contact with the boat.
Mana: I don't need to, like how Happy and Carle carry you and Natsu. I have Nii-san.
Lisanna: Awe. That's so sweet.
Wendy grunted glaring at Mana
Gildarts: Can I see that boat? It sounds so cool.
Erza: Anyway so what happened next?
Neos: Well.
Neos/Mana: Water Gills!
The two siblings cast their spell having gills marks on their neck. Neos have his front foot push down as their boat dive down. Mana point her finger up ahead.
Mana: [That way]
Neos give her a thumbs up.
Neos: [Right]
After sometime travel they reach it, the lost kingdom of Juhani.
Levy: Wait! The lost kingdom of Juhani!? One of the lost empires in the age of God?
Mana: Fourth age of humanity. It happened after the end of the age of God.
Neos: But after Ragnarok the god where kill and circle of rebirth started.
Mira: I don't see what that have to do with this lost kingdom?
Mana: After rebirth the amount of god left lower to the point of extinction the amount of pure blood gods can be counted with 1 hand.
Neos: They leave many artifact and remnant of the old god as a part of our world history.
Erza: So many complicated words...
Erza look a bit embarrassed.
Neos: Back to the story.
As the two siblings making their way into the lost kingdom, they are being chased by a humanoid shark monster.
Riding the boat through the ruin as the two try to not get tear to pieces by the monster.
Mana turn back, projecting a harpoon gun fire at the beast as it easily dodge the harpoon, she throw the gun away. As Neos bend left moving his boat to turn left, the shark monster also turn left not letting it sight off the two siblings.
They both can use their magic but casting spell took longer since water will get into their mouth making it harder for them to finish their spell.
Neos: (Note to self, I should add a way for me and Mana to speak underwater)
They see another shark beast with a literal blade on it head as it try to cut them, he move his boat to the right, more shark beast appear as the two sibling got surrounded by all sides.
Mana: Hmhmhhhmhh! (There are too many of them!)
Neos: (Screw it!)
Pushing his back legs down making his boat move upward as the army of shark monster follow.
Mana: Hmh?(Huh?)
Neos suddenly grab the back of Mana neck and throw the little girl upward sending her flying out of the water.
Erza: You did what!?
Both Kagura and Erza are grabbing Neos collar.
Mana: He throw me.
Wendy give of a small giggles imagining Mana screaming while being throw.
Elfman: Throwing a little girl isn't manly at all.
Neos: Big talk, I like to see you come up with a better solution.
Elfman: Uh... Well you could give her a warning.
Cana: Criticize him later what happened next?
Mana: HAAAAA!
As she fly out from the water.
Mana: Stardust Dragon: Silver Wing!
A pair of silver wings grow out from her back as she float a bit looking down, suddenly the water spark up with red lightning as many shark monsters body float up fry by the lightning.
Mana: Nii-san!
Neos and Striker rise up from the water coughing his clothes a bit darken.
Mana: Are you alright?
L.S: Yeah. *cough*
Dark smoke come out from his mouth.
Gray: Wait you get damage by your own lightning?
Neos: Elemental Mage have a resistance to their element. No one is immunit to it.
Mana: Water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water, as these charged particles can freely move.
Erza: Uhhhhh. What?
Lucy: Basically saying water conduct electricity.
Mira: Oh!
Neos: Anyway.
Now the two sibling in swimming into the ruin kingdom.
Mana: [Where should we search first?]
Mana use sign language to communicate with Neos as he does the same.
Neos: [We stick together this time, water isn't our field of battle.]
Mana: [Right.]
As they travel through the ruin they go to many room, many where abandoned until he reached a room fill with boxes, opening it they see shiny gold coins, jewelry and gems. Closing the box as the two sibling began to transport the riches into their inventory.
Natsu: Wait you two actually found gold!?
Happy: Aye sir.
Neos: Yeah.
Erza: How much money do you both have?
Mana: We lost count, now we're just keeping it in a share storage.
Cana: That mean you two are filthy rich. Right?
Neos: Probably, pretty sure I can bury Erza alive around 10ft with those gold.
Everyone Else: What!?
Everyone else except the two sibling yell hearing about the money they have.
Gray: You're joking right?
Neos: Why? It not like we can't do that, unless Erza actually fight back.
Erza: I won't mind taking a bath in a pool of gold and jewelry.
Mira: Oui!
Lucy: Wait if you two don't have problem with money why are you two still taking jobs?
Neos: I take S-Class jobs because it actually give a challenge. And some of it actually located in places we need to go anyway.
Mana: Other than the maid job by Mermaid Heel, the other jobs I took is 1 or 2 normal jobs and the rest are S-Class.
Everyone else: What!?
Everyone else yell in shock again.
Neos: Of course she's with me.
Erza: How many S-Class missions have you two go to?
Mana: I only been on 6.
Neos: 8.
This make some of the S-Class mages turn away while Gildarts just have a cheeky grin.
Gildarts: 12 years old and already 6 S-Class Missions. Not bad kid.
Mira: I only been on 1 and that was a failed.
Erza: I only been on 5... and I failed 2. Can't even compare to my little sister...
Lisanna: Mira!
Mana: Erza!
The two girls call out their sister names worrying for them.
Neos: Back to the story.
As the two continue to move through the ruin until they all reach a open room with a trident.
Mana: (Wow)
She turn to him.
Mana: [Can I take that?]
Neos: [Go ahead]
Both communicating through sign language, as they swim to it. Mana try to pull the trident out, her face began to turn a bit red before she pull the trident out holding it about her head in victory.
Mana: (I did it!)
Suddenly the ground began to shake violently as the ground crack open, as a giant octopus came out.
Neos/Mana: (The Kraken!?)
Neos turn to Quake as his his weight increase making him sink like a literal rock. Neos stomp the ground as rock spikes came out to hit the creature, one of it tentacle was about to reach Mana make the girl arms flailing as it slimy tentacle reach closer to her.
Mana: (Nooo! Get away!)
Suddenly the trident light up as the trident pull her spinning to a direction as she move out of the way of the tentacle. She flung to her brother headbutting him in the guts as the rock spikes hit the octopus.
Mana: (I'm sorry!)
Water began to go into his mouth as he quickly close his mouth using the gills in his neck, to filter out the oxygen and the water. It tentacles move to them as Neos grab his sister before stomped his foot again this time an earth wall came up and block it. Neos look down at her and she look up at him.
Their eyes met and she imidietly knew what he want to say, she raised the trident in her hand as Neos turn back to his base form. The two sibling was sent flying out of the water spinning.
Mana: So dizzy...
The surface water began to darken along with the sky as the sea monster rise up and a storm began. It tentacles rise to catch the two sibling, Neos then throw Mana up higher so the tentacles missed her as Neos body turn to light.
Neos: Split!
His body split slipping past the tentacles now there are Lightning Storm, Cyclone and Ice Neos.
Cyclone: Air Shot!
He fire air blast at the monster as an ice bow appear in Ice hand and lightning blades on L.S hand.
Ice: Crystalize Shoot!
L.S: Wrath of Neos Slashes!
His blades cut off the tentacles while the ice arrow freeze it. The sea monster easily shake off the ice as it tentacles regrow as it grabbed L.S.
L.S: Burst!
A burst of red lightning spark out electrocute the monster making it let go of Neos. As Mana began to fall down she see a bright light flash behind her.
???: Triple Contact Fusion!
Mana: Triple Contract-
She fall the water before she get to see her brother.
Natsu: Wait, Triple Contact Fusion!?
Gray: Stop interrupting flame breath!
Gajeel: We just get to the good part!
Natsu: What was that you ice maker!?
Erza/Mira: Quiet!
Both girls grab the two head of the fire and ice mages and slammed them at each other making the two of them faint.
Erza: What happened next?
Mana: Uh, well.
Mana quickly rise from the water as she look up at her brother. Her eyes widen seeing her brother clothes have a deep blue and dark cyan color. His body look a bit bigger and a pair of actual wing with feathers on his back.
???: Ultimate Typhoon!
And with a flex of his wing creating massive whirlpool appear spinning around as it takes Mana up with it before she was send flying.
Mana: NOT AGAIN!
Erza/Kagura: Neos...!
The two girls are now on top of him pinning him to the floor as their eyes glare at him.
Neos: I didn't notice she was sent flying by my spell, I was too busy not getting us both kill by it.
Cana: How do you even survive living with him for four years?
Mana: You'll get use to it, I was even at blame for some of his injuries and accident.
The girl said sheepishly while both of her index finger poke at each other.
Levy: Like what?
Mana: I kinda almost got him kill... multiply times.
They all look at the girl a bit worrying, until Neos speak up.
Neos: It isn't your fault.
Mana: But I got you poison and we have to rush to Takemi.
Neos: Okay some of it was your fault! Can we finished this story already?
Mana: Right!
After Mana was sent flying, as Neos fought the giant sea monster, after sometime he found her on the water surface. She was angry at her brother but soon she realized she didn't hold the trident anymore.
Neos: Look it's over there.
Mana: My trident!
As they make their way to it a giant fish with cat head rise up.
Neos/Mana: Heh? A cat fish? A fish cat!?
The beast bit the trident and began going back down.
Neos/Mana: HEH!? GET BACK HERE YOU OVER GROWN SUSHI!
The beast turn back trying to intimidate the sibling but it imidietly freak out seeing the two sibling charging at it with blades in hands, it freak out and accidentally swallowed the trident before diving back down in the water to try and escape.
Reality
Neos: And we send three days chasing it until we lost it.
Mana: That over grown fish sticks ate my trident. Just wait until I find it and actually turn it into actual fish sticks.
The girl pouted making an adorable face, Neos just patted her head as everyone began to laugh at the hilarious and anticlimactic ending.
