Chapter 1: First Evolution

A blood curdling scream erupted from Ryoma alongside a massive pillar of green light that rose through the heavens that was accompanied by extremely powerful shockwaves which obliterated the terrain for hundreds of meters from the epicenter. 

His body, mind, and soul were elevated to an unprecedented degree as side effects of the two hearts fusion. Each and every single cell inside his body was rebuilt to perfectly contain and utilize Getter Rays generated by the Heart, practically turning his body into the equivalent of Getter machines that can passively grow stronger and evolve by absorbing Getter Rays. Then his mind was greatly enhanced, making it able to seamlessly handle the massive amounts of information from everything he would absorb, along with the ascension of his soul to handle the burden of absorbing things with souls. 

He was now practically turning into the human form of Getter Emperor, albeit currently much much weaker than the real deal because he needs time and resources to grow and evolve. But even then, this cosmic horror machinery is still a force to be reckoned with even in its larval stage and this unsuspecting new world would be its first meal.

=====================================================================

[Fusion Complete! Congratulations Master!]

Theresa's cheering voice and the fading pillar of light signified the end of the excruciating process that felt like eternity for Ryoma. And He was now lying again on the ground but this time, it has been turned into a crater tens of meters deep and hundreds of meters wide.

"Ha… Three times…. Three fucking times i had to experience things like those!!! It's not even a day yet!! I can't get used to it, im not a masochist for fucks sake… but…."

After the pain faded away completely, he stood up and took a look at his own body that was now naked after the fusion procedure as his clothes had been blasted into smithereens by the previous light show.

He has grown taller plus his body has become much more athletic and robust than before. The feeling of endless amounts of energy flowing inside his body was really intoxicating, never in his life he felt so much more alive. 

He too realized that his mind had become so much clearer and could even process many more things at once. He could even remember every single thing from his previous life from childhood until the time of his death. Some embarrassing and painful memories that he had already forgotten even resurfaced, making his face twitch a little. 

"It's worth it… but I don't want to go through that again, ever! Anyway, how much time has passed since we began the procedure?"

[5 minutes, Master]

"Only that long? I thought it took like hours or even longer…."

[That would be the case if you wanted to be rebuilt into something else. But since you subconsciously still wanted to keep your human body, The Getter Emperor's Heart abided by your wish and only perfected your body even further. Furthermore, It's really familiar with human body too so the procedure became even shorter.]

"Makes sense…"

From what he could remember, the Getter Emperor always supports humanity for some unknown reasons. His chosen ones were mostly humans, but there was a case of an alien that became his chosen one but he fought for humanity too so this can't count as an exception. He even went far enough to suddenly act as a reinforcement when humanity was on a brink of destruction and turned the tide of the war by annihilating the home planet of the alien invaders. 

Ally of humanity but the enemy of all…..

"So…. next is finding out what world this is huh?" 

"ROAAARRRR!!!!"

Suddenly frenzied earth shaking roars echoed throughout the whole forest. Then loud footsteps of something humongous approaching could be heard along with small earthquakes. 

[Master, gigantic hostile life forms approaching from 1 and 6 o'clock]

"Ohh so we got company.. Theresa, Insert Shin Getter Robo in Quick Launch and prepare to trigger the Full Transformation Mode!"

[Affirmative!]

Ryoma then felt another immense surge of power throughout his whole body. The shared stats from Shin Getter provided him another huge boost of power to his already heavily enhanced body. Being more careful against something unknown is mandatory after all.

"Battle Wing!"

A pair of huge metallic bat wings unfolded from his back then he flew high into the sky in order to get a better vision of the entities that were currently targeting him.

"Hmmm… great, turns out I was transmigrated on an island in the middle of nowhere…"

Now that he was high in the sky, he now has a better view of the terrain and the two hostile giants. Furthermore, he could see the huge crater his fusion had caused, a mountain in the middle of the island, Forests which covered the whole Island, and ocean which surrounded it. 

"And those two giants… Hmm I think I know what world I'm currently in.."

He saw those giants in a certain anime. They are around 100 meters tall, have pale brownish skin, overly muscular body, some kind of green armor covering their left hand arm, bandages covering half of their face with a bulging eye visible in the part not covered by them, and somehow they wear shorts. Ohh and if he looked closer, he could see a humanoid figure inside the scar in the middle of their forehead. Overall, they looked like giant zombies that were controlled by little zombies like Dr. Zomboss. 

"Akame ga Kill… is it correct, Theresa?," he answered while dodging huge chunks of debris the size of a few story buildings that the giants throw at him leisurely. 

They were slow, too slow for him to take them seriously. And if his answer was correct, then nothing in this world could threaten him at all.

[Verifying the answer and visual proofs within the database….]

[.....]

[Correct Master, this is Akame ga Kill World]

[Congratulations, you have Completed the Main Quest "New Life! New World! New Opportunities!"]

[Rewards have been sent to your inventory]

"Nice…. Now let's annihilate these ugly motherfuckers! Theresa, disable the stats sharing of Shin Getter Robo!"

[Are you sure Master? The shared stats from Shin Getter will boost your combat capabilities by a huge margin and will provide you with more safety, please reconsider your decision]

"I want to test my own body first so weak targets like them are perfect. Just in case, prepare to activate Full Transformation if things go south."

[Your wish is my command, Master. Disabling stats sharing…]

Then Ryoma felt huge chunks of strength leaving his own body, making him a little nauseous but he can still keep his concentration that was proven by dodging another barrage of huge debris easily.

 "Hmm let's try this, Getter Beam!!"

He stretched his right hand and opened its palm, then a gigantic pillar of green light fired off from it into one of the giants, devouring its whole torso and everything behind it for as far as the eyes could see. 

"Sigh… seems like I really have nothing to worry about in this world… hm?"

He noticed a tiny bit of increase in his strength alongside the complete genetic information and memory of the absorbed zombie giants in his mind which were put in a separate place like a partition that he can access whenever he wants to. 

'Wait, hold up…. doesn't that mean i can replicate all kinds of genetically based abilities after i've devoured some parts of their users?.' he thought as his eyes widened at the realization.

Now He kind of understood why Getter Emperor is called The Enemy of The Universe, even in its initial stage of evolution it could already do this much. Then what about in the future? Maybe he can just eat concepts and use them? 

"Next is to test my physical power"

After breaking out from his musing, he flew to the other zombie giants below with speed a few times faster than lightning then punched its head with all of his strength. 

"HA!"

BOOM!!!

The poor danger beast's head and whole body literally go 'splat' and the explosion from the aftershock creates another huge crater that decorates the island.

"Damn…. nothing can really stop me in this world," he said in amazement while looking at the destruction he had caused.

[It's completely normal Master, after all you have fused with the core of machine that is called as Enemy of The Universe in its native reality, your whole being has been reborn to become compatible with it, and currently both of you and the heart are currently in the initial stage of your evolutionary path so you will definitely be capable of more amazing feats in the future!]

"Okay... Ah yes, I can't waste food." He then devoured the remains of the two danger beasts by firing another Getter Beams and gaining another slight increase in power. 

"Hehehe, it's time!" Then, he cackled while rubbing his hands in anticipation FOR THE GACHA!!!

"Theresa, do it! Roll the Gacha!!"

[Very well!]

[Using Mech Gacha Tickets x3]

[Establishing Connection with !%@&$&%#*!%]

[Shuffling gacha capsules….]

Then a tab showing three gacha capsules, one silver and two golden appeared before his eyes. and with a burst of light, they were opened, showing what was inside them.

[Congratulations! you obtained GM Sniper K9 x1]

[Congratulations! you obtained Zhen Xuan Wu x1]

[Congratulations! you obtained Zhen Zhu que x1]

[All Obtained Units will be placed in the Hangar]

"Hmm, great first pulls, one long range unit and two melee units that are from the same series. Quite powerful too, at least in their respective world. They have great utilities even though their raw power is quite low."

First is GM Sniper K9, a customized GM Sniper II that is made and used by Renato Brothers in Gundam Build Fighters. Like its base unit, the GM Sniper K9 uses sniping as its basic tactic, but the strategies of the Renato brothers enable it to use tactics that are unthinkable with other Gunpla. The K9 Dog Pack, which is the backpack part, can be separated and used as a self-propelled artillery unit that works in conjunction with the GM Sniper K9 itself to hunt down opponents.

Zhen Xuan Wu is the second generation of one of the Far East Four Spirit Beasts units, Xuan Wu the Black Tortoise from Iron Saga. Like its predecessors, Zhen Xuan Wu is an ultra close range fighter that uses its own limbs to decimate its enemies but unlike Xuan Wu, Zhen Xuan Wu has additional 4 arms on its back, allowing it to deliver faster and more devastating rushes. Representing the water element, Zhen Xuan Wu attacks have freezing properties, allowing it to hinder its enemies movements. Its trump card even allows it to freeze time for a few seconds.

Zhen Zhu Que, like Zhen Xuan Wu, is the second generation of one of the Far East Four Spirit Beasts, Zhu Que the Vermillion Bird from Iron Saga. Representing the fire element, Zhen Zhu Que was made for one purpose, to incinerate its foes to ashes as all of its attacks have devastating fire properties, including its feather drones that can shoot homing fireballs or flame lasers. Like a phoenix that was reborn from ashes, Zhen Zhu Que can restore its durability when it's in burning state, rendering fire based attacks almost useless against it. 

While their kits are powerful and have many uses, their raw power isn't that much, even the one with the strongest destructive capability among them, Zhen Zhu Que can only burn down a city in seconds. 

"But that's okay, the shared stats from Shin Getter will cover their shortcomings. Next is time to glow up! Use the Appearance Customization Ticket!"

[Affirmative, Initiating Appearance Customization Tab]

A character customization tab resembling the one in many MMORPG appeared in front of his eyes. It showed his current full body appearance, naked, then a selection of body parts he could customize on the right side of the screen. 

"Hmmm, why do I look so good already? hah and my Precious down here is bigger than before! must be because of the fusion process"

Short black hair, extremely handsome face with a dazzling pair of emerald coloured eyes, stunning athletic body that is 193 cm tall with 8 packs and amazing proportions which is not as lean as a swimmer and not as bulky as body builder either, and most importantly….. 23 cm long D!

He was quite good looking in his previous life, but now? He is a lady killer through and through. 

[Yes Master, it was like how I have explained before. Though you have to be careful because your current looks will attract some troubles.]

"Haaah, I know, they will be those kinds of troubles. Anyway, please close the customization tab, i'm already satisfied with my current looks"

[Closing Appearance Customization tab…]

That item was useless for him now, trying to change anything might just ruin his current looks. Now it was time for him to dress up, clothes maketh the man after all.

"Use the Custom Outfit Ticket"

[Affirmative… Opening Custom Outfit Tab]

[Do you want to see some outfit recommendations first, Master?]

"Very well, please show me"

[Yes, Master!]

[Examining World Information…..]

[Measuring the client's body….]

[Generating results…..]

After a while, Theresa finally shows him the selection of outfits. There are so many of them, even too many…. There were even yakuza suits and yukatas. 

'It feels like shopping to be honest…. i can make them myself but i'm no designer so meh'

After scrolling for some time, he finally found his pick. A black tight fitting long sleeved shirt with thin gray stripes, layered with double breasted white vest, a pair of black pants coupled with black and silver military shoes, white military coat, purplish blue tie, and metallic black gloves. 

'I might be mistaken for a high ranked personnel when i wear these, convenient'

The outfits are pretty comfortable despite their quite formal theme, he even did a split to test his pants and they surprisingly weren't torn apart. 

"Now that I've got the drip… I want to directly go and claim her but i'm worried about the control over my power"

Sometimes obtaining absurd amounts of power all at once will make the control of the said power an absolute mess and he was really worried about it. 

Especially now that if he wanted to completely capture the heart of a certain murderous, sadistic, but loving general, he needed to defeat her in a fight! Not just using a pure silly smile because he wanted to be the one in charge. Plus, he was really afraid of accidentally killing her….

"Hmm… then let's just stay here for a while. Theresa, set all the newly obtained units to the Quick Launch Slots"

[Affirmative, anything else Master?]

"Launch and took control of GM Sniper K-9 and Zhen Zhuque miniaturized feather drones to monitor these people of interest from the sky of the Imperial Capital and immediately inform me of their sightings and conditions"

After saying his orders, he uploaded the appearance of the people of interest that act as the plot points of Akame ga Kill World from his memories to Theresa.

[Your wish is my command..]

And immediately after that, a 18 m tall navy green mecha along with 64 palm sized vermilion feather drones appeared with a burst of light particles, then they flew away to the northwest of the Island in order to keep an eye on those characters.

"Now… It's time for the training montage I guess?"

Finished with the initial preparations for his future plans, he walked deeper into the forest to find something good for training dummies and some lab rats.
