Prologue: A NEW Dimension and NEW Shenanigans DOOD!

The "Netherworld", a parallel universe inhabited by demons where moral values are reversed from those of humans. Many versions and dimensions of the netherworld have its own unique and powerful demon known as "Overlords". Beings that surpass their titles of Demon lords, these Overlords have a very bad reputation that earned admirations and sometimes fame amongst demons of middle and lower classes that aspire themselves to be one of them. This world controls half of the "Human Realm" through Fear while the counter Balance force Known as "Celestia" governed by Seraphs support and guides the people through Faith and the light.

Our story focuses on one particular red scarf wearing Prinny who holds the title of *Netherworld Hero*. Chosen by his proclaimed mistress and boss Lady Etna he is tasked of getting almost every unpredictable jobs ever thrown at him at a moment's notice. Throughout his adventures he makes friends and enemies all the times but that did not discourage him of ever abandoning his duty… unless of course you want to taste the wrath of so called Boss but that's another story for another time. His personality and famed heroism had greatly earned him many achievements but the one that tops it all the most was his epic duel against the very Tyrant feared amongst all Netherworld Dimensions; Tyrant Overlord Baal.

Emerald Forest

A portal appeared through the darkness of the forest seemingly out of nowhere spitting out three individuals before closing up. This three composed of our lovable and heroic netherworld red scarf wearing penguin Hero Prinny but this time he is not alone as he is accompanied by his two other companions he made throughout his journey. His companions consist of Fuka's destructive but lovable little sister Desco and the silent and out of mercy mechanized red-caped penguin from the Land of Carnage Pringer X or X for short since you know… I hate pronouncing his full name and I have grown accustomed to calling him X… and no I'm not pertaining to the blue bomber okay?

"Ugh where are we?" I groaned clutching my prinny head because of the ringing I hear from it.

'Looks like where on another type of planet' answered my ever trusty companion/overlord friend Tyrant Baal.

'Well at least we didn't end up on another freaky area' standing up I dusted the dirt off myself.

'Last thing we need is another crazy round of fighting unknowns before transporting you and your companions away' said the Tyrant until he noticed something. 'Speaking of which where are our two other companions?'

I shook away the last of my dizziness as I took a quick look around for the other two after the statement of my inner self friend. I then noticed the unconscious Desco mumbling away in her dreams of world domination and Pringer X who looks pissed off as always as he looks like his ready to blast the whole forest off to oblivion.

"Desco? Desco?" I called out to my adopted little sister shaking her awake from her slumber. I almost feel guilty in doing this to her because of how peaceful and adorable she is right now but… duty calls since we don't where we are.

"Mm?" Desco groggily shook off the last of her drowsiness and yawning cutely before looking at her Big brother Prinny and smiling. "Morning Big bro!" she exclaimed tackling me for a hug… seriously though how strong is this adorable sister of mine!?

While I struggle for the conflict of my personal hug of death, I failed to notice Pringer X steadily scanning the whole forest using his two antennas acting as a Scanner/Radar… which is kind of a mystery for me. Then all of a sudden he picked up something and started shooting randomly behind several bushes trying to kill something that have been gathering and approaching all around us it seems. He then stops as I finally got out of my sister's grip and catching my breath while said sister goes on her battle stances ready for anything until black smoke starts rising from whatever the blast hit off.

"What the Nether-hell are you shooting at, Dood?" I asked after catching my breath. All I got from him was a stare and I mentally face-palmed because of forgetting of how he can't speak much to my ire and the snickering of the tyrant.

'Heh good luck getting an answer from him' snickered the Tyrant. I so totally want to kick his ass right now but I can't.

'So mind telling me why and what he's shooting at all mighty tyrant?' I asked the almighty Tyrant.

'From what I can sense he currently shot something made out of darkness because I can't sense any soul to what he just shot' he answered back to me after getting out of stupor. Oh goody soulless creatures are now curious of us. Seriously though can't this day get any better?

"Big Brother, Desco is hungry" grumbled Desco and pleading cutely at me. My Big Brother instincts kicked in and I reached out and rummage through my prinny bag and produced a Pudding I made personally for Lady Etna and gave it to her.

"Thank You Big Brother!" Desco exclaimed and hugging me before proceeding to eat her snack. I smiled at the cute scene but turned my attention back to X as he motioned for me to talk privately.

"So do you know where we are X?" I asked him forgetting for a second that he can't communicate with me normally.

"…"

"So we're in a planet called Remnant in another dimension"

"…"

"And we're on a place called the Emerald forest outside of "Vale" one of the four kingdoms"

"…"

"And the one you just randomly shot were creatures called "Grimm" huh?"

"…"

"…"

"…"

"… How the Hell do I even understand you now, Dood?"

"…" he shrugged to my question. Seriously though how the hell do I understand and held a conversation to this guy just now? Hmm… it must have been that time were we battled to the death? Or maybe the time when we have that staring contest? Or I should just let it go before my prinny brain gets fried for over-thinking things.

Anyways as me and X held our "conversation", Desco on the other hand had finished her meal and is now floating above the trees to get a better angle and view of things. As she does this, she noticed a building far from our location and a town as well and also a big bird that is now trying to get a meal out of her. But unfortunately this bird just doesn't know what it's going for because before it even get's to her, Desco blasted it to oblivion with her Laser beam tentacles out of her back… Goodnight Birdy.

As me and X noticed the blast from above the location of Desco, X noticed several signatures coming in every direction towards our location he then notified me about it and went to battle stance. I then informed Desco about our situation and told her to have fun obliterating the things that are after us. Heh this is just going to be one hell of a night isn't it?

Several Prinny Minutes Later and black smoke rising and environment destruction…

"Yep chalk this one as one of our official netherworld achievements, Dood" I stated looking at the destruction we just made and standing in the middle of a barren wasteland that was a forest before. Smokey the Bear would not be pleased.

'Nice destruction there Einstein' applauded the Tyrant in my mind for what we have done.

'Hehe thanks for the nether compliment'

"Big Sis Fuka would be overjoyed and proud of us Big Brother!" exclaimed Desco as she hugged me once more for letting her have fun.

"She sure would, Desco"

Desco hugged me for the third time and I struggled once more. I swear to the Overlords that she would be the death of me.

"…" Pringer X just stood there and started hacking the nearby database for any information. I then noticed a whimpering Alpha Beowolf as he told me earlier when the fighting is ongoing, trying to get away from us but he blasted it and leaving no evidence what so ever.

As the three of us celebrate of our achievement of first destruction in this world, I then heard the sound of breaking glass and the of two us minus X because his busy "Gathering information" turned our attention to the petite Lady with weird hair color combination that I vaguely recall of ice cream with that color… what was it again? Pink and brown… yup its official I don't know if this Lady is the poster girl for Neopolitan Ice-cream or not… but one thing is for sure… hmm ice cream.

The Ice cream poster girl looked at us and then the surrounding area back and forth before walking up to us and smiling with her umbrella unfolded.

"…" she asked smiling and stretching her free hand for a handshake.

"Yes we did if you're asking" I answered to her shaking her hand and smiling back.

"…"

"Nah it comes with the job, Dood"

"…"

"Our names you ask?"

She nodded.

"I'm Hero. Hero Prinny and this two are my companions, my little sister Desco and rival Pringer X. Dood" I introduced myself and naming my other companions.

She smiled and gave the two a wave.

"What's your name if I may ask, Dood?"

"…"

"Neo huh ...nice name" I knew she is the poster girl for that famous ice-cream!

"…"

"Hm? Where we come from?"

She nodded to my question.

"Well…" I thought of my answer before giving it to her. On one hand she is deadly and fun from what I can tell, while the other is either to trust her or not of believing us… the latter it is… unless she value her life if she ever misuse our "trust" or she will feel the wrath of a Big Brother, an Earth destroying lovable sister or a Destructive Walking Carnage Machine… it's her choice.

I then proceeded to tell her where we came from, a place called the Netherworld where demons inhabit the place and how the moral values are reverse, how it is ruled by supreme demons called Overlords, how we control and gain power from the "Human Realm" through "Fear", the world of "Celestia" governed by Angels of high order called "Seraphs" and gaining power through "Faith and the like".

I then went ahead and told my origin, my friends, my adventures, my eventual death and resurrection, how I became the vessel of the most feared Tyrant in all the Netherworlds, and how I was dubbed "Netherworld Hero" and finally how me and my companions ended up traveling and the rest was followed by more adventures and why we are here now.

Needless to say …she fainted. I don't know if its fear through shock or shock of what I just said… needless to say I'll say the latter… Why? Well how would you tell not if you are going to see her face right now …judging from the stars imprinting her eyes and a smile that I can't tell if it's joy or a sinister one… I'm going to go for both.

"Well Guys its official… "Welcome to our new Playground"" I stated while holding a miniature device created for building our headquarters while we are here courtesy of our resident Netherworld genius Lord Mao. "Heh let the shenanigans… Begin." as the sound of a building being constructed echoed throughout the now barren section of the Emerald Forest.
