1 Chapter 1 Commissioned by, Definitely not Dio
You know filling out a Cyoa while some kind of mirror clone of myself that got his powers thousands of years ago and decided to allow me to pick my own powers was harping about how easy I had it was honestly nice. Reminded me of my grandpappy who was in the military, and served in the war. And although he was a hardass his words held wisdom and helped me keep my life on the straight and narrow.
Hence while my opposite who apparently got isekaied to Nier Automata first was complaining to me about all those worlds that got destroyed in the wake of the countless ROB's shenanigans I nodded along as I filled out the form until I realized all the drawbacks and the world choices were based on dealing with worlds on the cusp of an apocalypse of some sort.
They had all flavors of the world ending. Zombies, the moon shattering, the sun dimming to almost nothing, nuclear, monsters, super volcano, and so many more options to say nothing of all the world options being ass, to begin with.
"Why in the world would I want to go to the world of 'The Boys', DC or Marvel, worlds with their higher level apocalypses when their points don't make up for the danger increase?" I asked wryly and my opposite shrugged.
"Thats fair... Hmm yeah that's honestly a good point, here I got you on the world options and I will comp the price for you to get a modified behemoth base, a couple of upgrades to it, as well as the entire base actually being a Warhammer 40k Navy ship that will grow as you complete worlds." He said and my points fizzed on the form and I looked at him before he sheepishly explained that regardless of if I took the options people would be watching me go 'save' the worlds so might as well make it more interesting and doable.
Even with this Cyoa being very much NSFW it still had potent powers attached to it, like beast taming, plant taming, and several other things and when I asked for advice about what magic system I should take with the grimoire option my opposite firmly nodded as he told me to get RWBY aura.
"Why should I take aura when I can get WoW, Fate, or any other more powerful magic?" I asked frowning and my opposite looked at me like I was stupid.
"And how will you cast any of those higher magic's without years of learning? Even if you spend all your points on increasing your talent and comprehension you will still take a solid couple of weeks before you could cast the smallest fireball... But Aura and later on RWBY elemental magic is damn near instinctive and comes with a mecha shift weapon with infinite ammo." He said pointing out how my first world was going to be a lower-tier zombie world as the only peaceful world of Nekopara was greyed out with an X on it.
So thus I continued to fill out the Cyoa with my Mecha Shift weapon being a smaller battle axe with a handle able to stretch it to make it a proper large battle axe and able to switch from using rifle and sniper rounds depending on the length of the barrel and the weapon will take my Aura to form within the gun.
"Hmm. I see you are also a man of culture taking androids with your base to help protect and manage it." My opposite said proudly but then he warned me about how the first ship I got in the new world wouldn't be all too big at all so be aware that not all upgrades would come online at the start.
"Alright, I think that about sums it up." He said as he overlooked my Cyoa and finally, he nodded, and then the glowing tablet I was using to fill it out turned to pure light and shot into my chest. "Well, good luck dude and use that Karmic battery skill wisely. It is the most potent power you have." He said as a portal opened up behind me and sucked me into it.

Landing in Japan and the knowledge that my first world to dip my feet into was going to going to be a mash of zombies from Left 4 Dead and Back 4 Blood I fairly instantly knew the world I was within being High School of the Dead, thankfully I was given a single day to get acclimated into the world and learn how to pull up my aura to defend myself as already by the end of the first night I was already hearing over Tv's and radios as I wandered the streets of Tokyo how people with 'rabies' around the world were attacking people.
No... the biggest issue to say nothing of the base zombies of this world was the Back 4 Blood method of infection. That system of infection relied on tiny worms that would infect the host and I had no doubt that the people drinking any tap water would be infected in the coming days before the word could spread to heavily boil all water. Not to mention the zombies and special monsters from that series even with my powers were dangerous.
A twenty-meter-tall armored ogre made out of biomass from thousands of humans and animals would laugh in the face of a sniper rifle bullet after all.
Coming into this world I had several powers that I hoped would carry me far into these worlds as its not like I could merely sit in my massive ship base on each world and just leave when things got too hot. No, I had to survive a certain amount of time while also saving the lives of the natives and the more I helped bring the world back to normalcy the better my score for the world would be and the better rewards I would get. The powers being.
Healer, You can channel healing energy through your hands and into the body of the target. This energy can repair damaged tissues, alleviate pain, and cure illnesses. However, you have limited reserves, which can be depleted with excessive use. You must be careful not to overexert yourself when using this power, as it can cause you to become fatigued or even unconscious.
Builder, Your superpower is based on the popular video game Minecraft. You can create and manipulate blocks of different materials and shapes, and use them to build anything you can imagine. You can also craft tools and weapons to help you survive and explore. Along with being able to open a portal to the Nether.
Karmic battery, You have the power to gain energy from doing good deeds, whether it's helping a stranger, donating to charity, or saving a life. The more good you do, the more energy you accumulate. And with that energy, you can perform middle level miracles, such as healing wounds, creating food, or manipulating elements. If you accumulate a significant amount of good deeds, such as saving 10,000 lives, you may be able to use this energy to perform a major miracle. Examples of such miracles include the true resurrection of a single person, the ability to travel back in time for up to a month, or the restoration of several city blocks to their former glory.
Grimoire, which gave me access to RWBY aura and its elemental magic though I had no idea how to learn how to access my semblance nor its magic.
Adaptive Evolution, You have the power of adaptive evolution. Whenever you face a life-threatening situation, your body will change to survive it. For example, if you are drowning, you might grow gills and fins. If you are on fire, you might become fireproof. If you are poisoned, you might develop immunity. These changes are temporary, but some of them will remain as permanent enhancements. You might become stronger, faster, smarter, or more resilient over time. You never know what your body will do next, but you always trust it to protect you.
And lastly Beast Taming, You have the ability to bond with any animal you encounter, from a tiny mouse to a majestic lion. You have the power to tame animals and enhance their natural strengths. You can make them loyal, obedient and fierce allies in any situation. You can boost their speed, agility, senses and even their intelligence. You can communicate with them telepathically and see through their eyes.
The beast taming especially was going to be useful later on in the higher tier worlds as it would allow me to handle the horrible and literally eldritch monsters that will invade higher tier worlds to say nothing of native monsters that will come to an issue.
So with all my ducks in a metaphorical row, I realized how the school in which the Highschool of the Dead series took first place in would be a perfect first base before the infected started mutating and likewise grew far more powerful. So with that knowledge in place, I decided to skip waiting for the cast to reach the bridge and what not, and instead I took in the large school that was surrounded by a four-meter high metal barred fence, not chain link but actual almost solid cast iron steel bars that surrounded the school at the lower level with a thick gate and the school and its surrounding buildings itself was on a raised platform with a steep hill and a staircase that was a couple of dozen steps long to reach the level where the school was.
"Hmm with my Builder power I can also fortify the school even more... I just hope the school itself has enough food." I muttered as I took in the school in the early hours of the day after I went to a nearby store and bought a uniform to the school just lying about how I was a transfer student and whatnot.
So while I watched students and teachers alike arriving in the school I bemoaned how I skipped over the plant manipulation ability as it had a stupid revised price due to its insane power and how it could literally give users infinite food but as a couple of hours rolled by I watched as canon rolled in front of my eyes and as I saw the male teacher attempt to fuck up the male zombie that was smashing into the gate.
I heavily and mentally screamed as I missed the moment with my battle axe in sniper mode and I saw blood spraying from the man's arm as the zombie took a massive bite out of it.
"Fucking shit." I cursed as I pulled the trigger on my mecha shift weapon and with a loud crack the magical round pierced through the air my previous life's great experience in hunting combined with my supernatural body made the zombie's head explode.
I then ran down into the school to see if I could somehow salvage this situation before I decided to say fuck it and play the magic card what with that man coming to resurrect in a couple of moments so even as I ran over I coated myself in the dark blue aura of my soul. "Get away from the bitten man he is infected!" I roared and the teachers froze and went to inspect the man.
The major terrible fact about Highschool of the Dead zombies combined with all the other factors of the other sources of zombies combined together, was the fact that the time to kill for its infection and change into another zombie was faster than literally any other series as within not even fucking ten seconds would a person's body turn grey with black edges to their eyes and extremity's and they would lunge with the sprinting power of the other worlds zombies rather just the base slow acting dull zombies this world was supposed to have.
So as the newly resurrected zombie lunged to its feet with blood coming out of his eyes and grabbed open the white dress shirt of the red-haired female teacher who was wearing glasses, ripping it open and exposing her yellow bra I grabbed the zombie by its other arm and threw him over my shoulder with my aura-enhanced strength confident in both my aura and my 'Healthy' body perk that would conceptually protect me from the various forms of zombie virus.
"Sorry for being slow." I sadly apologized softly as I swung down my battle axe onto the zombie's head and with a crunching noise the womanly teacher screamed as blood splattered everywhere marking my entry into this world like the worst kind of birth.
