I set my sights on the My Hero Universe, aiming to fill my arsenal with powerful quirks. My primary targets included Eri, Overhaul, Number Six, Star and Stripes, Eraserhead, Monoma, and, finally, Shigaraki.
Eri and Overhaul were relatively easy targets compared to the others, so I decided to focus on them first. My plan was simple: enter Eri's dreams and make a deal for her quirk in exchange for her freedom. Once that was secured, I casually took all the quirks from Overhaul's henchmen and the man himself. But I didn't leave without tormenting him first, informing him with cold satisfaction that he and his comrades were now quirkless. Watching his mind break under the weight of his hypocrisy—preaching about curing the world of quirks while using his own—was particularly satisfying. "Pathetic," I spat as I left him broken.
With Eri in tow, I hypnotized her to forget everything about the world of quirks and the horrors Overhaul had inflicted on her. To her, it would now seem as if her parents had died in an accident and I had adopted her. She would forget the world of My Hero Academia entirely.
Next, I set out to save another child: Tenko Shimura, who would later become Shigaraki. I carried the sleeping Eri as I traveled to an alternate timeline of the My Hero Universe, back to a time when Tenko was still a child, untouched by the darkness that would later consume him. I stole his quirk and replaced it with the Float quirk, which I had taken from a dying Nana Shimura before arriving. His father was furious at first, but with a minor hypnosis spell, I managed to turn things around. I made sure they would be safe, but just in case, I informed All Might and Gran Torino of their location and used hypnosis to ensure they would protect the family.
The rest of my targets were easier to obtain. I simply took their quirks at the moments of their deaths, whether from old age or battle. I didn't see the need to extend their lives, unlike the children. Finally, I stole all of War Arc Shigaraki's quirks, alongside those of Endeavor, Twice, Hawks, Yaoyorozu, Kurogiri, and, with some spells, One for All.
All these quirks brought with them the echoes of their former users. Though they were an annoyance, I had plans for them. I purchased a skill called Parallel Processing, allowing me to exist simultaneously between the echo world of quirks and the normal world. I also decided to train my Haki by holding the echoes back with sheer will alone.
During my quirk-stealing spree, I discovered an interesting synergy between Monoma's Copy quirk and All for One. By fusing them, I could create endless copies of quirks and store them within All for One. I could then exchange these copies in the system to gain points. Using a separate cell for parallel processing and the Six Eyes' automatic function, I set up a passive point income system.
Albedo and I returned to Nazarick. "Here," I said, handing Eri over to Albedo. "Give her to Pestonya to be taken care of. Make sure she grows up happy and loyal to me and Nazarick. And when she calls for me, I wish to be informed immediately. Do you understand?" I locked eyes with Albedo.
"Affirmative, Lord Gilgamesh," Albedo replied before teleporting away.
Now alone, I could focus on consolidating my new abilities. First, I upgraded New Order by fusing it with Takaba's cursed technique. The first order of this newly improved quirk was that I would grow stronger the more I fought. I added a binding vow to improve this: the more time I fought the same person, the less I would grow, down to 10% efficiency. However, if I fought someone new, my rate of growth would be even greater. This applied to both quirks and magic.
The second order was that all quirks I possessed would act as if I were born with them. This included the ability to power stack. The third order was that I would never be overwhelmed by the choices of abilities at my disposal. This allowed me to properly sort, combine, and execute my abilities without forgetting any of them.
These were the orders I could implement with full efficiency. I could do more, but this amplified quirk wasn't strong enough to fulfill my goals without some restrictions, thanks to the binding vows.
Now, for the points. My hit-and-run tactics in both the MHA and JJK universes had earned me a significant number of points, not to mention the hidden achievements and the points I gathered while galavanting in the Konosuba verse.
First, I upgraded the potential of my template's quirks and techniques to match Gilgamesh's powers, and perhaps even surpass them. I would still have to work to reach that potential, but it was a start. I also spent points to improve my Gate of Babylon. I added a cleaning feature to keep my treasures from getting dirty or corrupted, a perk to channel my Kaleidoscope magic through the gate, allowing me to not only travel the multiverse but also duplicate my treasures by letting them inhabit two spaces at once. This removed the burden of using the Kaleidoscope manually. Zelretch had his sword, and now I had my gate to do the same. It also prevented my gate from being closed without my permission.
Finally, I purchased a magic core. It was unfilled, as I planned to infuse it with various energies later. I chose the weakest one, but it had the potential to reach EX rank, allowing me to save some points. I began fusing it with my energy merging skill, combining Type-Moon mana, Spin energy, Hamon, cursed energy, Haki, the mana from the Overlord verse, and that of Konosuba.
