The library would be a great start to the day
A green skinned guy had been at a computer for hour's and did what looked like research with the amount of books he seemed to have.

All in all it was a good source of information for the dark lord in disguise of what he could only say was a male version of the Irka persona that the OG Aku used against Jack in an alternate future.
Aside from some looks from people on his way over, this disguise was working quite nicely since he was able to go in the library with our worry. Although he made a note to buy some clothes since he was technically naked just using his powers to form his body and of course the looks he was getting from people were starting to bother him.
Could you blame him he was an introvert before he was Isekai'd as Aku.
He wouldn't say that Saitama being here didn't bring him some fear. Ah screw it he was very afraid of the caped baldy that he's pretty sure if he had the parts he would've pissed himself.
Although he was unsure if Saitama could kill him he really didn't want try testing that out.
He figured out where in the timeline he was at least in the MHA sense but screw trying to figure out what this world's japan had to offer since it would be a headache to keep track of everything since when he searched up top heroes, he saw Omni-man as one of the top heroes of the world.
This world was pretty much a hodgepodge of a couple shows and animes that feature heroes and he didn't want to keep track after finding that out.
He didn't want to rule the world since he'd relay on his meta-knowledge on these shows and then when something unexpected came up he wouldn't be prepared for it. He would just settle for ruling japan.
He didn't know how OG Aku could deal with a galaxy spanning empire.
Ugh he just remembered the freaking species supremacist empire of the Viltrumites..... Eh Invincible could handle that he wanted no part in that since he was a lazy bastard (emphasises on lazy).
A thought had just interrupted him as he got up and walked out of the library and decided to search for someone by using magic by locking into a certain person's Aura... life energy? sorta like instant transmission from Dragon Ball Z expect more magical.
He heard voices but they weren't who he was looking for so he kept looking until.... he heard a young girl crying who's voice he'd recognize as Deku's Daughter..... ehem.... he meant Eri.... yeah.
The Isekai soul was a villain no doubt about that and he was serious about at least ruling Japan in his own way but he had standards dammit and besides is this version of Japan really that bad under his rule with elements of MHA and One Punch Man existing here, would he really be worse then those corrupt humans.
Probably not but at least he was honest about being evil.
He would save Eri for no other fact that he wanted that power to working with him since he'd rather not have her against him and it's not like she would be adding much to his personal strength unless he tweaked her power to affect him in order to get him back to his original state of The Black Mass.
Maybe... Maybe
He needed to save Eri and luckily he just managed to lock on to her signature and teleport there and that little girl who was considered the embodiment of innocent was all kinds of cut up and bruised had a tear stained face cause she was left alone with the pain that was inflicted on to her by Overhaul's Quirk.
"Why hello there little girl would you mind telling me what your name is?" He appeared as Aku since he wouldn't lie to her using a different persona since he if he did that it would slip up eventually so it would be good to just deal with her as Aku rather than a pretender
Eri had looked at Aku's face and was terrified and why wouldn't she be with his horrifying appearance like that of a Yokai. Due to her young age and some of the times that she ran away she was told by Chisaki that if she wasn't compliment that a Yokai would come and devour her soul for being a bad girl.
"My name is Eri, are you here to take me away" She look was going to cry.
The Isekai soul didn't know how to respond to this since while he may have volunteered with children for a while he never encountered anything like this before.
"Yes" He held out his hand to hand and she took it.
"From now on you are the daughter of Aku and with that being said" He zapped her magic in order to do give her an extra horn that was similar to her other one except black. He wouldn't need to do anything else aside from being a decent caretaker to her and she'll be singing his praises.
He just teleported out of there since he would kill Overhaul eventually but only on his term plus he would be too easy..... well he did have this whole idea to just leave a ransom note asking for a lot of money... yen? for Eri's return but Overhaul would be a threat since he wasn't sure if his quirk could affect him not in the sense of actually hurting him but more like if Overhaul managed to take his essence and become similar to something like Aku-Jack and that would just be a stalemate since he wasn't sure if he could control him or not.
Despite being dumb, he wasn't going to risk actually fighting Overhaul himself.
Aku grinned a wicked grin as he got an idea, oh how ironic would it be if he "Trained" Midoriya in order to take out Overhaul alongside Eri like in the original.
He had his scent due to his enhanced senses so he could find where he lived. He didn't have anything else better to do and he'll get around to conquering Japan eventually.... maybe...
Well he was still afraid of Saitama but he might as well join him in Z City and be neighbors since according to him it was cheap and there were monsters around and plus there was.... THE MONSTER ASSOCIATION!!!
He completely forgot about them, did they exist here if so then he could take over that since he was Aku he should another title to his name King of the Monsters sounded nice.
While carrying Eri in his arms he made a phone in his hands to find where Z-City was and it was kinda far from his position so he teleported there and found it.
He didn't care about quirk laws since it's kinda dumb if a person had teleportation why wouldn't they use it to make their lives easier. He hoped that he didn't send up any flares but he doubt anyone would search for him in Z city.
He took a building for him and Eri it was just in awful and using magic again to make it clean and nice and do all sorts of basic necessities for him and Eri.
He would do one last do for today before hitting the hay even though it was still a little early but after casting so much magic he was exhausted and he couldn't tell if it was due to mental exhaustion or just that he was just tired from waving his hands around to cast magic.
Either way he was beat.
He cracked his knuckles and started to create one of his all time favorite villains.
Demongo but he wouldn't just leave him as a weak as he was in his start no he would make him a little stronger maybe up to a tiger level monster since he wanted Demongo to grow in power since he'd given him his ability to suck the essences out of people... pause
After a couple minutes he had done it! Sometimes he wished he had become Demongo since while Aku was a great villain he loved Demongo more.
There he was bowing to him.
"How may I serve you my masstar" Demongo said with his high pitched voice.
"You will be my most loyal minion and grow your power until you are given an invitation to join a group of monsters that should be growing there power within this city's sewer's and if I get even a hint of treachery from you there will be some consequences do you understand me Demongo"
"Yes my Lord" He said as he bowed again.
"Good now leave" and with that Demongo had flew out of the windowing and into the streets of City Z where Aku was sure he'd run into some monsters that would increase Demongo's power.
As for Aku himself and just sat in the newly magically created couch and just closed his eyes letting himself drift off to his dreams.
