Chapter 1: CH1: Yoink Goes Rias Gremory
How long had he been in the world of DXD before he caused absolute chaos? It wasn't like he had done it on purpose. Zack saw a perfect red-headed waifu and yoinked her straight to his demi-plane. It wasn't like he kept her locked up or chained. She had a couple of kilometers to travel easily with plenty of wild game to hunt, and there were berries, nuts, and the agios fruit that drove people insane upon eating them.
Okay, that wasn't his main problem. He found himself in the DXD world after falling off the chaos ladder and gaining a skill. He checked his status.

Zack Sin managed to stop himself from taking many useless skills he couldn't level and focused solely on his primary skill. All he did was find fauna and flora he liked, and he pretended to be in the other world while taking advantage of the salary and shopping the gods provided. Zack bought an agios seed because the name sounded cool. The plant was cool. It increased mana and life attributes by 25 levels each and increased potential by 50% for each attribute. Unfortunately, the side effects were a little terrible.
The trees were made so powerful by the divine blessing of God Bael in the other world he didn't visit.
How was he supposed to know the girl would see the golden fruit hanging from one of his experiment trees and make a beeline for it? Zack had berserk bears under his monster-taming skill protecting the fruit, but she disintegrated them when they tried to ward her away from the trees.
Then she didn't just eat one or two. No, the girl chowed down on 50 and continued eating them while he watched on in horror as her body changed.
Black lightning crackled across her skin, and her wings had grown and separated into six pairs with small holes dotted their surface. Long spiraling horns grew from her head, and a forked tail encircled her waist. Her vibrant red hair was luxuriously long and glowed in the dark. She also walked around in the nude, growling and hissing as black orbs appeared before blasting any birds foolish enough to get close to the orchard. He kept her around the fruit as she guarded it.
Zack was barely able to direct her with his Monster Tamer skill. The fruit synergized with her better than he imagined, almost like it was made for her. Zack thought about what he knew about DXD but couldn't figure anything out. Bael was a demonic house in the underworld. What did that have to do with the god Bael from another world?
She was in no state to return to Kuoh, and a barrier surrounding the school kept people inside while a scary redhead with all the mana in the world questioned them.
How was Zack supposed to know so much shit would happen after he snatched her? He did know about her, but 5 minutes after she vanished, the school grounds were isolated. Zack thought that he would have more time. People always vanish in anime, and it took forever for people to find out.
Zack checked his phone. He was sitting at his desk staring off into the ether when the door opened, and a busty maid with snow-white hair strolled in. He didn't know her name and resisted the urge to use his system to find it out. He would be in a terrible situation if he showed any sign of guilt.
It was an accident. He was only admiring her hair when he accidentally grabbed her. That's what he did: He saw a plant or animal he liked and took it from nature.
He joined the school recently, and suddenly, the class's idol, one of the so-called great ladies, goes missing. It had been all because of his urge to collect things in his inner world. Rias was pumping mana constantly and expanding his world every second she was inside it, so maybe it was worth it. If he could escape this situation, perhaps he could get Rias to calm down and send her home.
The Satan who followed the maid in looked all business and had no humor in his features. Little lightning sparks danced around his hands as Rias unleashed but far more controlled.
"So you are the new student who transferred from where exactly? There are no records of your birth. Did one of the gods send you to start a war with our faction?" Sirzechs asked.
Zack remained silent, trying to think of anything to get him out of his current situation. What did he have?
He had Rias. Every minute in the real world, a hundred passed in his inner world. With Rias, his mana gains were insane. Time passed quickly, and his demi-plane swelled with the mana monsters that had expended there. Rias was no exception, significantly after she had changed.
"Speak; my king demands your answer."
"I have no," Smack!
His head bent to the side. It hurt. Despite all his training in his demi-plane, he wasn't at the level to fight them. He was still in the G rank and wouldn't cross into the F rank until he ranked up his skills.
Rias was already in the F rank as a demon, but that was busted. Nothing in his demi-plane was F rank.
So Zack had bent most of his focus on bringing her back to a semblance of sanity. There were only so many times screeching to get ahold of yourself could do to bring someone back from chemically induced berserker rage. Her mind might be mush from all the hallucinogenic fruit she consumed. Maybe it wouldn't be so bad. Perhaps she would only need a few more hours to regain herself.
When he next checked on her, she was masturbating and smiling at him like she knew it was him, and he was downright uncomfortable.
"You can bring me back if you want or leave me here. I don't mind. This has been a nice vacation."
"Thank god," Zack thought in her general direction, and she winced.
"Hey, there is no need to throw around such harsh language. You're the one who kidnapped me, you weirdo. So where am I? Are we in the underworld, but the sky doesn't look like it? "She flapped her wings, and suddenly, she was at the edge of his demi-plane, poking against its membrane. "This place is weird. Am I inside your sacred gear? Was I so beautiful it activated for the first time?"
"I'm speaking with your brother. What do I say to get him not to disintegrate me and doom you to being trapped on my farm forever."
"Oh, tell him I know about his secret sex doll and will tell Mother next time I see her if he doesn't let you off the hook. I'm going to destroy Betrothed, and it's all thanks to you. Oh, could I plant some of this fruit in the underworld? It doesn't seem to mind my demonic power." Rias said.
Zack focused on the trees and felt like cheering. Her body didn't neutralize it. Her demonic energy acted as a counteragent to the hallucinating blessing in the fruit. It was divine, and Rias neutralized it. Any old demonic energy might do it, and it was possible that if he found some that boosted plant growth, he could significantly improve the fruits.
"Give me a few hundred tons of underworld soil, and you have a deal," Zack said.
"We're good for it, and I can also get you the best fertilizer in the underworld. My family has a massive herd of camels," Rias said.
"Rias says if you don't let me off the hook, she'll tell your mother about your secret sex doll the next time she sees her," Zack said.
"Are you talking to her right now? Wait, is she using this to get out of her marriage with Riser."
"I can neither confirm nor deny it," Zack said.
Demons like Sirzechs were utterly unaffected by his Monster Tamer skill, but Rias was still affected. Maybe it had something to do with the fruit having unforeseen effects. Or it could be that her life force and magic were raised drastically simultaneously. Zack thoroughly planned to abuse the hell out of this discovery.
"That girl caused us so much trouble and then got cold feet when we responded as we should. Her peerage is worried sick, and it was all a scheme," Graffia said.
"You boy, I can't rightly reprimand you for going along with this foolishness. What did she promise you."
"300 metric tons of camel fertilizer from the underworld filled with demonic power," Zack said.
"You know demonic power isn't the best for growing things in the human world."
"Let's just say I have some fruit trees that desperately need it. I'll open a portal for her now." Zack raised his hand for theatrical purposes only. A portal opened, revealing a window into his Demi-Plane.
Lush bushes filled with red fruit dotted the floor of a dense orchard with large black-barked trees, lush red leaves, and beautiful golden fruit weighing the branches down. Only a few craters dotted the landscape, quickly patched up by his direct control over the demi-plane. Rias had already used the power of imagination to make herself a new pair of clothes. She returned to her human form; only her magic power had spiked to far higher levels, and Zack felt she was suppressing it.
Their eyes met, and Rias smirked at him. Zack felt endangered.
"Brother, as you can see, I'm fine, and all of this was a big misunderstanding."
"You will be punished for this young lady. When your father receives the full report, he will be furious. What if he pushes the wedding up further?"
"I'm willing to battle Riser in a rating game now without my peerage if that's Father's stipulation." Her magic power shot up before she quickly calmed it down and took a bite from one of his golden fruits after saturating it in her demonic power.
"We should make a parfait out of these. Do you have any other weird plants?"
"Those berries you stashed in your pockets are highly addictive painkillers. I don't recommend eating them."
Rias blanched and rummaged through her pockets before tossing the berries she swiped back through the portal before Zack closed it.
"I don't think Father will let new piece prospect join you. However, a world full of strange plants does sound useful. I've never heard of a sacred gear like that. It's like the garden of Eden but also not." Sirzechs said.
"Brother, you know how no idea is original. Maybe the sky father decided that there could only be one garden of paradise and sealed the other away." Rias said.
"Well, this has been a trying day, but you have paperwork to do, and I have memories to erase. Don't leave before I do. I can go ahead and give you the first delivery of fertilizer." Graffia glared at Rias, who only stuck her tongue out. "Some of us must hold to our side of the bargain, or no one would ever deal with demons again."
…
Zack couldn't believe his luck. He got away with it. How lucky could a guy be? He was almost home free with no holes blown through his body and a spicy redhead nominally under his influence. Monster Taming didn't make monsters obey him as enslaved people. It made them predisposed to like him.
Black feathers rained around him as he stopped and looked up. A gothic Lolita stared down at him with raven-black wings and so much cuteness. She would look fantastic standing on one of his agios trees. The raven-black wings would contrast nicely with the golden fruit aesthetic.
A light spear appeared in her hand as she stared down at him. "You feel stronger than normal. I bet you have a sacred gear inside of you. It's unlucky for you that I found you." She flapped her wings and flew straight through an open portal that closed behind her, and he kept walking. Zack waited for someone to freak out over a missing Gothic Lolita. When nothing happened, he returned to his apartment and masturbated furiously to his memories of Rias naked.
…
All right, maybe he errored slightly. A twelve-winged angel with a flat chest and three black halos floating over her head road him on the muddy ground. Her flawless white skin glowed in a healthy luster as she raised her tight ass and pounded down, squeezing his cock deep in her tight love tunnel.
"You stupid, sexy human. I'm going to ruin you. No one else will ever make you feel as good as me, and you'll feed me your delicious fruit every day. I'm going to go up to heaven with you in my arms and fuck you on Michael's desk all over his important papers. Oh, I'm cumming thinking of his stupid perfect stoic face now."
Zack had no idea who the hell she was. He tossed the gothic Lolita blonde into his demi-plane because he panicked and was defending himself.
"I don't have to take orders from anyone anymore. Look at me."
Zack stared at her impeccable blonde hair tied up in a big black-and-white bow. Light radiated from her body, with hints of darkness moving through it. Zack remembered that not only did the fruit increase someone's magic, but it also raised their potential.
He reached out and grabbed her firm ass in two great handfuls. The multiverse traveler leaned forward as she shook her hips and wrapped her 12 wings around him. She licked her lips and whispered in an unknown language in his ear. Her pussy sucked at his cock and gripped him like she was trying to wring him dry.
Maybe he should be more careful and make some monsters stronger than bears that couldn't deal with flying opponents inside.
"While that sounds like fun, let's get to know each other first," Zack said.
"My name is Mittelt, and I love creampies. Fill me up." The fallen said, and Zack groaned as he came into the crazy girl high off her power. That was it, no more tossing people inside.
He ate a few bites of fruit and didn't get the hype. Yeah, his mana and life attributes were shooting up, but that was what the fruit did, and it would be less effective in the E grade. All it did was take care of two attributes. That was hardly enough for him to reach the F grade. Zack would have actually to train to get stronger.
…
"So you want me to guard this place," Mittelt said.
Zack built a small castle next to the orchard, which is expanding. It might not be a good idea to start a supernatural arms race until he's ready.
"Yeah, if someone somehow manages to break into my demi-plane, I want you to stop them from stealing our fruit."
"So it's our fruit now," Mittelt said.
Zack smiled. His balls were life raisins after only a few weeks of training in his demi-plane.
Why was she affected similarly to Rias? Something wasn't adding up. He needed to do some research and maybe steal more angels.
