They got out of the elevators to the final 10th floor and found Fumio and Black Sperm waiting for them. He was greeted, hugged and in awe of the new push cart. He was shown the dream vision and was incredibly shocked by it. "Mom! That's just...wow..."

"I know. But we know the truth of what happened now," Mitsumi sighed.

"Oh. The other bedroom below us. I never asked. Was that also decorated?" Saitama asked.

"Yes. It was matching on both sides, just reversed in room looks. This way no one can argue on better styles," Metal Knight chuckled from his hovering robot.

"Good. Hmm. And that dining place?" Saitama asked him.

"Recall the setup from the dining hall in City X. It is a miniature version of that room and half the size of a party room. As agreed, none shall sit in the master dining chair. I have enabled it to collapse down on itself to remain hidden away while you are gone," Metal Knight assured him.

"We'll want to put some nice decorations on the walls. Like those portraits and stitched rugs," Tacki pointed out.

"Easily acquired. Leave that to me," Metal Knight chuckled.

"Hmm..." Stable Rock mused and looked at the hallway to the main apartment door. "What...is on...this floor...?"

"Not much on walking in, actually. The elevator section sort of curves around to the main room, as you can see. The walls are hollow in case we wanted to do something, though," Metal Knight suggested. "There are no other rooms on this floor, so it's much like the room below us. Just a short entrance to display something and the rest is for the main penthouse room."

"I have...an...idea..." Stable Rock chuckled and focused. The hallway walls suddenly vanished away to reveal ten feet of blank space to the main walls on each side. He climbed out of the push cart, grew larger and focused for intense wealth to start falling from his shell in waves. A large ridge of solid gold rose up from the ground to help contain the loose wealth like a banister at three feet high, and he made small hills of wealth.

The entire strip he did made up twenty feet up to the main room doors from the elevators with ten feet filled in from the pathway. It would be as though they would walk through a massive treasure vault to reach the bedroom. The highest mountain of wealth stood well over ten feet tall, and it would easily be a good two feet in depth at the lowest sections. Then he moved to the other side to do the same thing.

"What...are you doing...?!" Mitsumi gaped.

"Yes! Don't stop!" Saitama squeaked out with excitement.

"Wow..." Garou blinked and saw several two foot wide stalactites of solid gold drop down from the ceiling. Now these were covered with gems and just out of reach of anyone touching them.

"A few of those gems would easily set me up for a few years," Bang chuckled. "Even into an early retirement!"

"Oh?" Stable Rock tilted his head at him. "You...have...debts...?"

"Not really. And you don't need to give me anything," Bang started before blinking at the mound of sparkling gems shoved at him. "Oh...ah..."

"Yours...to sell..." Stable Rock snickered. "Cold Snap! Make...an ice...wall...to shield...the stones...?"

"I can do that," Cold Snap beamed. "I'll make it crystal clear, too!"

"Will there be a way that I can go in whenever I want?" Saitama asked.

"From...your room..." Stable Rock nodded. "A...side door..."

"Yes! Treasure hallway! To go with my treasure bedroom! I love it!" Saitama said with a boyish giggle of delight.

"Oh, geez..." Mitsumi groaned to get the others laughing.

"Look...down..." Stable Rock said. The main runway was now a sheet of gold with small bumps in it to keep things from slipping. Small gems now encrusted the sides of it up to the golden barriers to be a half foot in width for decorations. Gems even sprouted to cover the walls in a form of shimmery glitter. Now there were solid gold poles at four inches around that shot up from the ground to stand at six feet in height. They formed small cages on the tips of them to hold the same, massive diamonds that were in the party rooms on the prior floors to make nine poles on each side. It was almost like lanterns holding the massive diamonds on each side of the path in matching form.

"Mitsumi. If there is one other place that I want to live close by other than our main apartment..." Saitama started.

"It's here, right?" Mitsumi had to ask.

"Yes. Unless we have our bedroom with wealth like this. It's here. Right here. This is what I always wanted," he said with a nod.

"You want this more than me?" she asked. Garou cringed with laughter and had to squeeze Lily to stay calm.

"No," Saitama said flatly. "I will dump all of this to have you with me. Without question. You know this. Everyone knows this. This is nice to have. You are a need to have. See?"

"Oh. And if I chose to walk away from all the money...?" she said with a small smile. Now he looked at her with a serious neutral stare.

"Stop it," he said to get her laughing softly. Then she went silent at how he gazed at her. "You are completely priceless. Nothing is worth more than you. Just by you being with me...you make me the wealthiest man alive. With or without money. I couldn't care less about that. It's you that makes the difference."

"Ah...oh..." she blushed hard.

"But I'm not complaining about the extra money. That's a bonus," he grinned a bit wickedly and got her squeaking at his tight squeeze. "I know you're numb to all of this. But I'm not. I love seeing this! But I love seeing you at my side even more. So don't think that I love all of this more than you. That will never happen. Okay?"

"Okay," she smiled and let him kiss her ravenously. He made a motion to the bedroom and paused when the double doors became solid gold. Then they became encrusted with gems of all types and sizes.

"Yeah. We can move out of the apartment to here. That's not a problem," Saitama said while staring at the doors. Mitsumi rolled her eyes, and Genos easily pushed them into the penthouse space. That was when they realized it was completely empty. There was the main bedroom in the back with a luxury bathroom, a deluxe kitchen large enough for Orotsu and a small staff to work in, and a gorgeous dining room space with large windows facing the city sunset. Two more guest bathrooms, two extra guest bedrooms and a living room when one first walked in made up the rest of the floor.

"I can share a room with Cold Snap so you can turn one room into a nursery," Fumio nodded. "We can decorate our room just fine."

"What do you need me to bring?" Cold Snap asked.

"You should totally get a fold out couch bed for the main room. It can be emergency living space," Tacki chuckled.

"We need some wonderful hanging lights from Isobe's collection," Mitsumi beamed. "See what he thinks?"

"He fully agrees and is picking things out now," Inichi chuckled.

"Would it be possible to get solid gold tables and counters? With gems all over them? Like...a border?" Saitama asked with a grin.

"Gold wouldn't be good for cooking on. It would be best with slate with golden veins through it. We can do back splashes in the kitchen as a border around the sinks and counters," Cold Snap said. "I'm talking to Orotsu right now. He wants to be here to inspect everything."

"That's fine. He would know best," Mitsumi agreed. He was quickly brought to them from Cold Snap's blue spark. Orotsu moved straight into the kitchen and looked at Metal Knight's hovering robot. A heavy discussion was now made to acquire some very specific equipment to be used in the off hours of Neutral Grounds. He was adamant to be wherever Mitsumi was going to be staying.

"I refuse to let anyone else cater to her needs. I know Anno may be the only other exception, but only if I know I cannot be there for her. And that won't happen," Orotsu said calmly while inspecting the cabinets.

"You don't have to do that," Mitsumi said softly.

"I want to. That's my choice," Orotsu chuckled. He shifted into his human form to ensure he had free reign and movement through the whole kitchen. He did like how the central island in the kitchen was free-floating to move around as he liked. He studied the hanging suspensions for tools, pots and pans on the ceiling for easy reach. He even tested the sink and installed oven. "The oven needs to be a quadruple burner. Or even with six burners for my cooking needs. This one can be moved to the Neutral Grounds kitchen as an extra cooking stove for Anno."

"That can be done," Metal Knight agreed. Siren was still in his lap in his underground base, and she nudged him softly. He muted the microphone to give full attention to her.

"You...don't mind doing all of this for us. Right?" she asked softly.

"My dear, Siren," he chuckled. "I already said that Mitsumi is family to me. She's a baby sister and introduced me to new technology. Even to you! And, I said this before, but this is most fun I've ever had! I get to be creative! As much as I enjoy building new attack robots and testing things, it's nice to see things from other perspectives. It gives me new ideas on how I can apply defensive measures, too, by hiding them in plain sight."

"So, the money also doesn't bother you?" Siren chuckled back.

"As Saitama said, the extra funding is a bonus," Metal Knight grinned at her. She laughed softly with him and kissed him passionately. He unmuted the microphone and began to place orders for various soaps, bathroom supplies and even some nice nursery furniture. Tacki had Genos scan a whole list to report to Kianna to inspect what was needed in the main apartment complex, too.

"I'm getting tired..." Mitsumi sighed and pressed into her husband's neck.

"Oh? Okay. Rest," he nodded and lay back a bit more for her. He ensured the blankets were secured around their hips to keep things hidden. Not once did he separate from her to keep his growing son happy. She ran a hand up his costumed chest to get him to look at her. "Crap..."

"What?" she frowned.

"Your eyes. Yeah. Eh...is there a button I can push on here? Or move me into the bedroom with her and close the door?" Saitama asked the others. Genos was quick to push them into the master bedroom. The pets in the cart got out to start inspecting the room to work on furniture and room designs. Stable Rock lumbered in before Genos closed the door so he could help.

"We can ignore things, Dad," Cold Snap said.

"Not when you're like this as my son. Change your form or go out there," Saitama ordered him lightly. Cold Snap blinked at this and shifted into a smaller version of his stag form. "Good. Ah...Mitsumi...?"

"Husband..." she murmured in a sultry way. He growled in complete response and fully tackled her. Cold Snap moved to lower his antlers at the door just in case anyone tried to get in. Even the fans moved from Mitsumi's belts to hover around the room protectively. At an odd sound outside the bedroom, Saitama turned to glare at the intrusion. Mitsumi turned his face back to hers to remind him to ignore it all. He returned to relishing in her scent and complete warmth of her embrace.

"We must be quieter!" Fire Flight warned the others when they set in the beautiful lighting. "I was just informed that Saitama almost berserked!"

"What?!" Kamikaze blinked.

"He is much in the mindset of his prior days with Mitsumi. The 'bedroom days' from what Shenjou just showed me. He is...unpredictable now," Fire Flight said lightly. "Mitsumi has brought this mood back out from what her son desires for protection. They desperately need to stay home tomorrow to balance this. Every other day will need to be like this now."

"Every other day?" Kamiko asked with complete concern.

"Yes. I have been sensing the fire building within her. It is not good," Fire Flight sighed. "Even Cold Snap had to become an animal form to stay safe with them. He is guarding the way in with the fans."

"I hope Mom will be okay," Fumio frowned. Black Sperm nodded and let himself continue to get held. Back in the closed bedroom, Saitama finally brought Mitsumi to the peak of pleasure she needed.

"Are...you okay...?" Saitama managed to pant out. He rolled onto his back to let her nestle into him with complete contentment.

"I think so..." she mumbled and sighed hard.

"Gonna need a bath at some point," he said and yawned. Tangled Vine had jumped into the cart and carefully pulled the blanket around them neatly with his tail. Then he carefully moved to snuggle against Mitsumi to purr heavily.

"Such a good kitty..." she said with exhaustion. Cold Snap turned from the door and tilted his head at Saitama. On seeing him nod, his son reverted into his human-like self.

"You okay now, Mom?" Cold Snap asked.

"For now," she smiled. He giggled at the fans when they settled around and on the cart. Blue Ripple had climbed back into the push cart with Overgrown Rover to settle around their feet. Stable Rock snorted and lifted himself up to sniff at Saitama's face. That got Mitsumi laughing at it.

"What?" Saitama asked his pet. Now he saw how the walls were set with massive diamonds of sheer size and various coloring. A glittering diamond disco ball was set in the middle of the ceiling, but it was also the base light for a ceiling fan of crystalline blades. Saitama rose up slightly to see that the floor was a gold base with small diamonds of various sizes dotting all over it. Now he looked at his earth monster pet with complete shock.

"You...like...?" Stable Rock asked and tilted his head cutely.

"I love this," Saitama said point-blank to get Mitsumi laughing at it all. He reached over to get his pet swooning at the head scratching. "What about the bathroom? Should we have ice themed diamonds in there with white gold?"

"Hmm..." Stable Rock mused and backed down. Then he lumbered into the bathroom to start revamping a lot of the fixtures to gold and gems. He replaced the basic tub with a golden one lined with gems, the standing shower was now slate with streaks of gold with ice-clear crystal doors and even the toilet was made to match the bathtub.

"Are you seriously going to crap on a gold toilet?" Bright Bolt asked. Mitsumi found herself laughing hard at that.

"It's gold?!" Saitama asked to get all the strong monsters laughing. "I want all of my toilets to look like that!"

"You are going to crap on your wealth?" Mitsumi had to ask.

"In it. Not on it. In it. There's a difference!" Saitama said to get the monsters laughing even more at it. "And it doesn't stay! It gets flushed!"

"Oh, dear..." Mitsumi sighed. When the bedroom door was opened by Genos to move them out, it took all that everyone had to keep from outright laughing. Of course, Bright Bolt had to mentally share the conversation.

"Let's make treasure beds in all the bedrooms," Fumio grinned. "And they will only be for here. Is that okay, Dad?"

"Yes. That's fine," Saitama nodded. Tangled Vine and Stable Rock moved to get to work. Now that the rest of the penthouse was getting set with golden walls with gems with the floor set to be the same in the other rooms, the furniture started to get looked into.

"You know he's gonna want all gold, silk, variously colored velvet and gemmed up furniture," Tacki grinned. "This penthouse is literally a live-in treasure vault. Also, if we ever want him to come back to the original apartment, then we'll need to revamp that place, too, to match this. Think about it."

"I am curious on what it would be like to sleep in a treasure bed," Fumio admitted. That got Saitama laughing softly. Mitsumi noticed the elegant, gold and crystal light fixtures being placed all over from Isobe's collection. Tacki had made sure all of them were working and fixed up properly. When dark red drapes of velvet came in to line the windows on golden curtain rods, Mitsumi actually found herself finding a small appreciation for it.

"Oooh..." Saitama grinned on watching her eyes start to light up. "Is this finally starting to catch your interest? As much as mine?"

"If it's done tastefully, yes," she admitted. "I like elegant furniture. Beautiful pictures and rugs. I like seeing things that almost resemble the dining room in my childhood home."

"And even cute kitten pictures?" he chuckled at her nod. "So, I know you mentioned it before. I wonder. The chests in the training rooms. Would those be acceptable for you?"

"Hmm...yes. Those are elegant and are part of my heritage with the clan," she agreed. "Even the family chest that uses rings to open it."

"Ah! Okay. Now I get what you like. So, I have an idea of something to display outside the elevators," Saitama grinned. Stable Rock and Tangled Vine were already on it from his thoughts. As they now began to construct an elaborately made chest of gold and wood, Mitsumi had a small idea.

"Stable Rock, you can't make pearls, right? Since those are made from oysters? I was thinking of a beautiful pearl necklace of sorts. But those aren't metal, right?" she asked him. Stable Rock paused and looked at her with a grumble to show she was right.

"He can't make them. But I can..." Blue Ripple snickered.

"What?!" Saitama asked. Now the others looked at Blue Ripple. Stable Rock chuckled and had a small pile of extremely grainy sand appear. Blue Ripple levitated one grain in the air to snap down on it. Then he made a motion with his mouth as though swishing it around before spitting out a beautiful, silvery white pearl of complete perfection. It was a good inch around and stunned everyone.

"I was wondering how we got pearls in the doors of your themed floor," Mitsumi chuckled. "Or were those purchased?"

"They were purchased," Metal Knight confirmed. "When we started on the themes, I was told what we needed to have. Stable Rock was able to find them and install them with his gems. Blue Ripple, can you make the pearls any color at all?"

"I can. If the sand grain is pink, the pearl becomes that shade," the water monster nodded. Tacki gestured to one of Blue Ripple's fans to come over so she could inspect the handle. She studied the fan veins and picked up the pearl to examine it. Blue Ripple already knew what she wanted to do. "I can make pearls as small or as large as you need them."

"Good. I know the fans are fantastic as they are, but I think small pearl inlays would be nice. With tiny diamonds," Tacki said and began to make small spacing motions with her fingers. "Child Emperor has the designs for these fans, so I think I'm gonna call him and do a redesign. A small one, that is."

"I can call him for you," Metal Knight offered.

"So, what's up with the chest?" Saitama asked.

"We will...make...a decoration...from it...on this...floor..." Stable Rock winked a glowing amber eye. "For the...elevators..."

"Will it be filled with treasure?!" Saitama asked with excitement.

"I would like to see it filled with actual jewelry," Mitsumi smiled.

"And gems! And loose gold! All of it spilling out before you see the main hallway! Yes!" Saitama grinned mischievously. "We can do that!"

"I can make some jewelry stuff for it. I can get on that right after the fans I need to make," Tacki nodded. Mitsumi chuckled and looked away. Now Saitama looked at her questionably to get her to talk.

"I want to train again," Mitsumi sighed and ran a hand up her husband's chest. He looked at her with a small smile. "It really does feel good to train."

"Okay. We can make plans for that," he nodded.

"And...hmm...why do I feel like I want to punch something...?" she blinked. Now he looked at her and found himself grinning. She gave him a look and sighed hard before snuggling into him.

"Yeah...my power seems to be infiltrating a bit much, eh?" Saitama chuckled. He ran a hand over her back to calm her down. Then he thought. "We need punching bags for her. Not for me, obviously, but I think we're going to need a few for training with, anyways. Can we get a few good ones?"

"I can see what will be available and best in quality," Genos nodded.

"I'm starting to feel restless..." Mitsumi frowned.

"Remember how I said before that she would get urges to train? This is one of those urges," Fire Flight said. Shenjou seemed to frown, but he noticed Mitsumi's eyes start to glow again. He was quick to point it out.

"Crap! Can you all finish this place without us? I think I need to run with her around the track at home. We'll come back here later, and we still have stuff to do today, too. The place is pretty much done, right?" Saitama asked while quickly fixing up clothing under the blanket. Mitsumi rolled her eyes with boredom to show she clearly had to do something.

"Mitsumi?" Tangled Vine asked. She looked at him and forced a small smile. Now she squealed when he jumped onto to her nuzzle into her. He purred deeply and kept nuzzling until she was completely calm again.

"Thank you, kitty," she sighed and cuddled him. "I still need to do something, though. I know I'll be cooped up later, so I want to do something now. I'm normally not like this, but..."

"It's from our son. I get it. We'll work with it," Saitama said to calm her. He got out of the push cart and lifted Mitsumi out to hold her. Then he looked at Cold Snap and said, "Son, we need to get home. I know we have some monsters to look at and possibly kill. Who all is staying?"

"I should go with you," Kamiko said. Genos also planned to go with them. Fumio wanted to stay to help with the furniture decorating. Black Sperm was clearly staying with Fumio to protect him.

"I need to finish your fans. I'll go with you," Tacki nodded. Kamikaze glanced at Bang to show they were both going back.

"I want to see how you plan to train. It may give me tips for Lily," Garou chuckled. Lily blushed and nodded.

"I want to help finish up here," Fubuki smiled.

"Rendor is back at home with Miss Tatsumaki," Inichi chuckled.

"I shall head down to the restaurant after finalizing what I need in the kitchen here," Orotsu said from where he was still evaluating the kitchen. "We may need to duplicate what we need back at the apartment home."

"We can do that!" Siren chimed in from Metal Knight's robot.

"If you...need something...let me...know..." Stable Rock snorted.

"Yeah. Where they go, we go. We have enough of our power here to work with anything at a distance," Bright Bolt nodded his horse-like head. Blue Ripple had made quite a few pearls of various colors and sizes for the penthouse. Fire Flight knew that she had to follow them to keep an eye on Mitsumi's growing son.

"We should check on Wind Crane Clan Mother first," Mitsumi said.

"Okay. We'll be back later tonight," Saitama nodded. He found his head turned to Mitsumi's face when she used a single finger on his chin. A kiss was planted on his mouth in such a way that he found himself growling in it. "Crap..."

"Dad! Hold on!" Cold Snap said. He was quick to send his parents back to their main bedroom in City Z with an ice blue spark. Mitsumi's fans followed swiftly in their own way to always be with her.

"We have...crap to do..." Saitama grunted and got locked in a possessive kiss. At the feel of her hands moving to get his costume off, he groaned and lost his senses. It was fifteen minutes later when he became aware of what happened. He noticed the pets were in the room. Parts of his costume were all over the place with hers. He had her locked to him in such a way that his body was refusing to let her leave his side. "Ah...damn..."

"Hmm?" Mitsumi asked while nestled into him under the blankets.

"Our costumes...are they...okay...?" he grunted and moved slightly to look.

"Tacki has to fix them," Bright Bolt chuckled. "She's here and waiting. Cold Snap is outside the door to keep others out."

"Craaaap..." Saitama grimaced.

"It's okay. She plans to make a set of costumes for emergency removal with hidden snaps. It's needed for Mitsumi's pregnancy, so she'll study how the costumes were torn apart to ensure where to place the snaps properly," Blue Ripple chuckled. "She knows it wasn't done on purpose. Now that you're alert, we'll gather up the pieces. At least the buttons stayed on! It was mainly the bottoms that were a bit roughed up. Don't worry about it."

"I..." Mitsumi started. Saitama pressed a finger to her mouth to gently silence her. Then he held her close to show she wasn't at fault.

"I'm going to tell you again. Don't. Say. Sorry. Okay?" he said softly to get her to shiver and nod. "We're all going to work with this. We know it's needed from my son. What's happening now may likely happen with the next one. Just don't apologize for this. I know we have a few things to do now. Just let me know when you think you're good for us to dress."

"I love you," she said with a touch of defeat.

"And I love you, too," he said tenderly. "And what's that tone for, eh?"

"I just...have so much to do today with you. And I wanted to check on Wind Crane Clan Mother..." she frowned. He nodded and pressed a hand to her belly. Then he paused at the soft gasp of relief she gave out.

"Mitsumi?!" he blinked.

"It just...feels good...when you do that..." she shivered. He frowned hard at this and paused at something he felt. Now he examined her belly and noticed the definite extension of her womb.

"Okay. This is worrisome," he admitted. She whimpered softly and got cradled. He thought hard and muttered, "I think I see why you were told that you can only handle four kids out of safety. If they're all like this...well...okay. We'll see what happens."

"And...if it happens...with one...right after another..." she winced.

"Eh...yeah..." he sighed. "I can only hope your body instinctively keeps mine from berserking out if it does come time for you to have kids again. I mean...ugh. I just don't know..."

"I'm sure that everything will be fine," Blue Ripple assured him. "Worry about it later. Focus on her and her needs right now."

"Yeah," Saitama nodded with complete agreement.

"Ten more minutes like this?" she asked. He nodded and reclined back in the treasure bed. She snuggled into him, and Overgrown Rover was quick to trot over to them. It laid itself right over his hand to keep it on her belly. Then it huffed at him with a small whine.

"Thanks, doggy," Saitama sighed. He noticed that Mitsumi had fallen into a deep sleep, and he glanced at the other pets there. He saw the fans on the walls to show they were alert, but resting. They must have followed us back from Cold Snap's teleport. Okay. I'll let her sleep. I'm sure something to eat will be made soon. I'll have to convince my son to let her move around again.

We do have a few things to do now that we're home. I'll give her an hour to sleep. That should be plenty of time for the others to prepare our 'guests' and get things ready. And I want to see Miu's murderer first. That one will be killed on sight. As she said. No mercy. No excuses. Absolutely none.
