Songs in the Void: A Multiversal Score

Scattered Cherry Blossoms Universe, Human World, Japan, Kuoh.

After lunch ended, Tatsuo did as he said he would. He played the piano for the people at the Alaverus Mansion. However, when most of them tried to head upstairs to his guest room, they were confused when he stopped them. He then pulled the piano he made while in the Arifureta Universe out of his [Inventory] and put it in the livign room.

"Actually, now that I think about it, there shouldn't have been a piano in that room." Shiba Miyuki, one of James' [Bishops] from his second peerage, an exceedingly beautiful young woman with long black hair, blue eyes, a nearly perfect figure, and an almost perfectly symmetrical body, said while resting her right index finger against her chin. "I wonder why we never thought about that yesterday."

"It's because we're getting used to the crazy stuff that comes with being a devil, Miyuki." Tatsuya replied.

"I guess you're right, Onii-Sama." Miyuki said with a nod.

Meanwhile, everyone else found seats to enjoy the music. Kunou also returned before Tatsuo started playing. Then, Tatsuo spent the next few hours playing the piano. Though, he only sang the first song, which he received feedback on from everyone with an ear for music.

After the music was done, the group just hung out and did the things they liked to do. Though, it should be noted that neither Rhea nor Sona returned that night. In fact, they did not come back for the next few days. Sona also skipped training each of those days. Yet, despite being worried about Sona, everyone, even the members of her peerage did their best in training, determined to make their [King] proud when she returned.

At the same time, Tatsuo and Tio continued to learn [Dragon Slayer Magic] from Irene. And while it was relatively straight forward for Tatsuo, as he was attuned to the element of [Space], or rather [Void]. Tio was having a bit more trouble. Because she was well attuned to two elements, [Fire] and [Wind]. And Irene had no point of reference for such a thing. At least, the Irene in this world didn't. However, in the world where [Dragon Slayer Magic] should have come from, Alfonzo's and Elicia's world, there was at least one example of a wizard using more than one type of [Dragon Slayer Magic]. Though, they did not learn said magic in a conventional way.

Even so, Tio decided that she was determined to learn two kinds of [Dragon Slayer Magic], [Purgatory Dragon Slayer Magic] and [Gale Dragon Slayer Magic]. Even if she knew it would take more time and effort than just learning one. Luckily, Tatsuo knew from the Fairy Tail series that someone could learn more than one kind of [Dragon Slayer Magic] thanks to God Serena Even if he only learned it because he had several Dragon Slayer Lacrima implanted into his body.

Like that time passed without issue. Though, Tatsuo did notice something that he did not like. Despite how much he had trained during his time in James' Universe, his [Stats] had not increased at all. His [Skills] had no issue increasing in rank, though.

Yet, until he returned home and had a chance to speak with his mother, there was nothing Tatsuo could do about it. So, he decided that he would continue to train hard until his [Dimensional Travel Ticket's] time limit was reached.

Eventually, the normal routine was broken on the evening of the fourth day of training, or Tatsuo's, Aletia's, and Tio's fifth day in this world.

"Come on, Cuzz!" James shouted as he raised the controller in his hand over his head. "What kind of bullshit is this? How did that weak ass move eat through my super?"

"Face it, James." Tatsuo replied in a smug tone. "I'm just that good."

"Yeah, fuck that." James replied. "Run that shit back."

"*Sigh* I guess you won't be getting revenge for your grandmother, will you, James." A mature woman's voice asked in a somewhat amused tone.

"Nah, I got this, Grandma." James replied as he glanced in the direction of the voice.

When he looked at the owner of the voice, what James saw was an exceedingly voluptuous woman with extremely beautiful facial features and lightly tanned skin. Also, she had long white hair that fell to her hips and the most enchanting purple eyes anyone in the room had ever seen. Wrapping her sinfully curvy body was a sheer negligée while a pair of black stockings covered everything from the middle of her thigh down to the tips of her toes. And that woman was leaning on Tatsuo, draped over him as if she were a cheap suit.

This woman was Lilith, who along with the original Lucifer, created the Devil Race. Though, it would be more apt to say that instead of creating the Devil Race with Lucifer, she was used to create the Devil Race by Lucifer, as the 72 Pillar Devils, along with the six Extra Devil Houses were created via a ritual rather than Lilith giving birth to them. Instead, the ones Lilith gave birth to through natural means became the Succubi.

On a side note, Aletia was completely livid at the way Lilith was continuously trying to seduce Tatsuo. Unfortunately, her powers of seduction were too much for even Aletia to overcome. Meaning, she could not get too close without being affected by her. As a result, she was unable to drag that white-haired bitch away from Tatsuo like she wanted to.

Usually, Lilith did not appear in front of James in this form. Rather, she usually showed herself in a form that looked similar to Ophis. Though, instead of grey eyes, she had purple eyes and wore her hair in a ponytail. Yet, when she came back from taking a trip to a hot spring in the Underworld and saw Tatsuo, she immediately turned back into her succubus form.

Lilith then tried to seduce Tatsuo. For some reason that no one understood, like Maria, who was also a succubus, Lilith was immediately drawn to Tatsuo, as well. So, she basically threw herself at Tatsuo. Yet, Tatsuo paid her next to no attention, aside from being polite to an elder, that is. As for her attempts at seduction, he treated them like air.

That's not to say that Tatsuo did not find Lilith absolutely gorgeous. In fact, the only woman he would ever think of calling more beautiful than she was, was Aislynn. Also, he was not turned off by the thought of her having been with another man... Or two, if her being Adam's first wife was to be believed. Rather, Tatsuo was completely turned off by the way she acted as if it was only expected that he fell to her seduction.

"You just lost." Genkai intervened before James could pick his character for the next match. "Pass the sticks, Kid."

"Come on, Genkai." James said as he shifted his gaze to his [Pawn]. "Just let me get one more."

"You've already said that three times, Kid." Genkai shot back. "And I've waited long enough. You're not getting your grandmother's so called revenge. Just give up."

"*Sigh* Why you gotta be so straightforward?" James asked as his shoulders slumped. He then passed the controller to Genkai. "Fine... Take it. I'll get that revenge eventually, though..."

"Keep telling yourself that, James." Tatsuo said with that same smug smile on his face. "If you tell it to yourself enough times, it might even come true one day a couple of millennia in the future."

*Flash!*

Hearing Tatsuo's trash talk, James grit his teeth and clenched his fists. He then turned to look at Genkai again, prepared to ask for the controller back. Before he could open his mouth, however, a [Teleportation Magic Circle] appeared in the corner of the room. And judging by the symbols on the circle, it was someone from the Sitri Clan. Meaning, it could be Sona and/or Rhea.

When the teleportation was complete, two women were revealed. However, Tatsuo had only met one of them, Sona. Though, he did recognize the newcomer. 

With Sona, who was struggling to free herself, wrapped in her arms, the newcomer, Sona's older sister, Serafall Leviathan, one of the Five Great Satans, was a beautiful young woman appearing to be in her late teens and standing about 5'3" tall with long black hair tied into twin tails, bright blue eyes, a petite, child-like figure, and disproportionately large breasts. AS for her attire, she was dressed in a frilly, pink and black magical girl's uniform that showed off quite a bit of thigh and a generous amount of cleavage. However, instead of a cheerful smile, like what her source material would suggest, she had a solemn expression on her face.

"So-Tan, which one is he?" Serafall asked while scanning the room for the person Sona and her mother said might be able to cure their father. "Hurry up, point him out to me."

"Let me go first, Elder Sister." Sona said while struggling with a red face. "Once you do, I'll show him to you."

In response, Serafall stopped scanning the room with her eyes. She then turned to look up at her younger sister with an adorably confused expression on her face.

"I don't get it, So-Tan." Serafall said while tilting her head to the side cutely. "Those two things aren't dependent on each other, are they? So, why would you ask me to do that?"

"Please, just let me go, Sister." Sona said in a pleading tone.

"Hey, Sona, Sera-Tan." James said while waving his hand at the sisters. "How's your dad?"

As soon as the two heard James' voice, they both turned to look in his direction. A moment later, big, comical, anime tears started welling up in Serafall's eyes. Then, she finally let go of Sona before running towards James and throwing herself into his arms.

"Jay-Kun!" Sona cried as she buried her head in James chest. "Father is awake. But the doctor said he had no idea when he would fall asleep again or for how long!"

Meanwhile, as Serafall explained the situation to James, and the rest of the room by extension, Sona made her way over to Tatsuo, who had gently pushed Lilith away. And because she knew this was important, unlike the little video game matches, she let him go. Though, the look in her eyes made it clear that she had not given up on having him, for a reason that she was unsure of, as well.

"As you heard from my sister, my father is awake right now, Tatsuo." Sona said as she slowly and respectfully lowered her head. "So, if you are willing and able, mother will bring him here right away. 

"Huh?" Tatsuo intoned in confusion. "Wouldn't it make more sense if I were to go to him?"

"In most cases, that would be true." Sona replied with a nod while adjusting her glasses. "But this case is special. First of all, if we were to teleport you there, Lord Beelzebub would be able to detect your illegal entry into the underworld. And he would undoubtedly have questions."

"Then, let's just go on the interdimensional train." Tatsuo replied, excitement shining in his eyes.

Seeing the excitement in Tatsuo's eyes, Sona could not help smiling despite herself. She then shook her head before she shot him down.

"Unfortunately, that would open up a whole other can of worms." Sona replied. "Because if you were to enter the Underworld through the official channels, then, everyone with high enough clearance would get a report about you. And that would lead to more than just the Great Satans knowing about you. And not all of them are as... cordial... as we'd like."

"So... Basically, no one outside of this mansion knows about us coming to this world?" Tatsuo asked. "Not even Sirzechs Lucifer, Rias' older brother?"

"Well, let's just say that he doesn't have the most trust among those living here." Sona said in an awkward tone.

Deciding he did not need to know, Tatsuo just moved on with the conversation.

"Anyway, you can bring him here whenever." Tatsuo replied. "I'm ready to do it whenever."

"Thank you, Tatsuo." Sona said, nodding her head again. "The Sitri Clan will repay you for this. I swear it on my name as the Sitri heir."

"Seriously, kill that noise." Tatsuo said while waving dismissively. "Although we haven't known each other long, I'd like to thank that we're friends. So, don't think me for helping you like this, Sona."

'Friends, huh?' Tatsuo thought to himself. 'This is probably the first time I've actually called someone a friend out loud. Hell, three months ago, I don't' even think I would have understood the concept. Man... A lot has changed since I turned fifteen, huh?'

"I understand." Sona replied with a nod. "Well then, if you'll excuse me, I'll let Mother know she can come with Father."

With that, Sona turned around and moved to where most people teleported into the mansion. Then, she created a [Communications Magic Circle] and contacted her mother. At the same time, a pink and black blur slammed into Tatsuo and grabbed him tightly by his shoulders.

"Hey, So-Tan said your name was Tatsuo-Kun, right?" The pink and black blur, Serafall, asked while shaking Tatsuo back and forth. "You're the one who can heal my father, right? Well, you can call me Magical Girl, Levia-Tan. I protect the Underworld, Love, and Justice. By the way, do you wanna be on my show? You would be great as a---"

Unfortunately, Tatsuo was unable to respond. Serafall was shaking him so hard that even his well-trained senses were being overwhelmed. On top of that, her grip strength was insane. He was starting to lose feeling in his arms.

*Bang!*

Luckily, someone was there to save Tatsuo from the emotional Satan, as the butt of a crimson red spear struck Serafall on the top of her head, causing her to let Tatsuo go while covering the spot where she was hit.

"Ow~~! Scati-Chan, why did you do that?" Serafall asked in a whiny tone.

"Because the boy was about to lose consciousness due to your incessant shaking." Scáthach replied as she rested her spear over her shoulder. "Not to mention, you might have broken his arms had I not stopped you. And he needs his arms to use his [Purification Magic]."

Immediately, Serafall's eyes widened in surprise and fear. She then turned to look at Tatsuo's arms. After that, she raised her hands above her head. Then, she brought them together and made a heart with her fingers before moving her hands around and mumbling some kind of incomprehensible magic spell.

"Now!" Serafall said ash she stopped moving her hands with the heart symbol placed in front of her left breast. "Pain, pain, go away!"

*Sparkle!*

In the next instant, the heart-shaped space between Serafall's fingers lit up with pink and sky blue light. Then, it burst forward in sparks of light before raining down on Tatsuo. However, the whole thing was just for show. There was no healing effect at all.

"Uh... Thanks..." Tatsuo muttered while trying to regain his senses. "I... Urgh! Feel better now."

Though Tatsuo dry heaved a little while saying that, he managed to give Serafall a smile and a thumbs up. In turn, that caused Serafall to wipe a bead of sweat off her brow as if she had just finished a day of hard work.

*Flash!*

At that moment, another teleportation happened. And when the flash of light disappeared, Rhea appeared with a handsome middle-aged man with short, shiny black hair, purple eyes, and a haggard expression.

Understanding the man to be Dante Sitri, Tatsuo stood up from the couch, though he was still a bit unsteady. Even so, he, along with Serafall, Scáthach, and James, made his way over to the Sitri couple.

"Tatsuo, this is my husband. Dante." Rhea said as she noticed Tatsuo approaching. "He said he's willing to let you try."

"That's right." Dante replied. "Though, I'll admit, I don't have much hope of success. But Rhea and Sona asked me to give it a try. And since you said that at worst, nothing will change after your attempt, I chose to give it a try."

Nodding in response, Tatsuo reached out to shake Dante's hand, which the older man reciprocated.

"It's nice to meet you, Lord Sitri." Tatsuo said as he shook Dante's hand firmly. "Like I told them, I can't make any promises. But this is better than doing nothing. Especially since there's little risk of things getting worse."

Dante nodded his head in agreement. However, when he tried to release Tatsuo's hand, Tatsuo tightened his grip. Then, when he looked at Tatsuo questioningly, he was surprised to see that Tatsuo was frowning.

Dante was not the only one to see the frown on Tatsuo's face, as James, Sona, Scáthach, Rhea, and Serafall also noticed.

"Tatsuo, what's up?" James asked in a concerned tone. "Is the Sleep Disease too much?"

In response, Tatsuo sighed tiredly while releasing Dante's hand. By now, the entire living room had fallen silent while everyone's eyes were focused on him. He then took a deep breath and shook his head.

"No, I can do it." Tatsuo replied. He then looked into Dante's eyes. "As for the extra-long handshake, I was assessing just how difficult it would be to cure you. And all I can say is... *Sigh* I'm gonna be running on E by the time this is over. But... You'll be free from this Sleep Disease."

Hearing that, the Sitri family's faces lit up. Then, they all hugged Dante happily. Meanwhile, everyone else's expression softened, as well. Yet, there were a few people who looked even more tense than before. And they were James and Cu Chulainn. Because from the way Tatsuo sighed, they knew he would be so drained that moving the following day would be difficult. Yet, there was no way that Scáthach would allow him to skip training, either. So, the only thing they could do was pray to everything unholy that Tatsuo would survive the next couple of days.
