After getting a thorough explanation from Gaia about his Status and at the same time having the chance to learn some important information along with it, like how each Level was separated into different realms, Zero continued on with inspecting the other functions in the system; starting with the Inventory.
The situation with the Inventory was as Zero had guessed; it had an infinite space that would be able to fit anything except living beings inside of it, although the teen did find the latter aspect a bit of a pity.
There were two things within his Inventory at present, well, technically three things: a purple book and a sword sheathed inside it's golden-blue scabbard.
As soon as the black-haired teen saw what was within his Inventory, his face gained a happy grin and his eyes lit up, especially as they locked onto the sword and scabbard.
"Hey Gaia, how do I take <Excalibur> and <Avalon> out of the Inventory?"
Zero asked impatiently as his eyes never left the legendary armaments on the blue system screen.
[As Gaia mentioned earlier, the System is connected to Master's soul so anything in the System within Master's authority can be accessed as long as Master will's it. In simple terms, Master just needs a thought to be able to summon things out of the System Inventory.]
Gain explained while giving her Master a look that said 'Why are you asking such a rhetorical question?'.
"Right, I knew that. I guess I was just too excited that I didn't bother thinking about it. Haha."
Said the teen in realization before he concentrated his thoughts onto both hands which were held out in front of him. Gaia had already hopped off her Master's palm and onto his head where she sat down peacefully watching the whole process.
Thankfully, both Zero and his fairy didn't have to wait long as only a second later, a flash of golden light appeared before dying down to reveal a magnificent golden-blue scabbard with it's sword sheathed inside. Even without seeing the blade, one could imagine that the sword was equally as stunning as its scabbard due to the elegantly designed hilt already exposed in the open.
"Well? So light? And what's this feeling I get when holding them? It's so… comfortable."
Asked the teen in surprise as held <Excalibur> and <Avalon> atop his hands. He had imagined that both armaments would have weighed a lot more, even with his currently enhanced saiyan body, but obviously he was wrong.
If Zero didn't feel the slight downward pull of gravity acting upon his arms as he held them, the teen would've thought that they didn't weigh anything at all. And this comfortable feeling… it was so strange and foreign to him yet at the same time it felt natural. It was as if they had a connection with him.
[Master, the reason why <Excalibur> and <Avalon> feel so light and comfortable in your hands is because they have been bound to you and recognize you as their wielder. A bonus to this is that Master will also gain a strong affinity towards swords, which is another reason why Master might be feeling that way.]
Gaia's words had cleared his doubts.
'That's pretty neat… I guess my situation is a bit similar to Shirou Emiya's, having <Avalon> and all.'
The teen thought in his head about how gaining an affinity towards swords was pretty similar to an anime character he had watched previously.
"I'm assuming the Dimension God did all this?"
Zero glanced up at Gaia who was sitting on his head looking down at him. The fairy nodded her head and responded cutely.
[Mn! The Creator tied both armaments to your soul when he gave them to Master, just like the System... though there is a little side effect of doing so.]
The System Fairy said before giving the teen a big jump with her last words.
"Ha? A side effect?! Is it anything bad?!"
Zero hurriedly asked. It wasn't like the teen was being pessimistic or anything when he asked; he was just making sure that he was okay and assumed the worst on instinct as a 'side effect' usually wasn't a good thing.
[Yes, but Gaia isn't sure if it is bad or not.]
Stated the fairy.
"Well? What do you mean?"
It only took a second for Zero to calm down due to his Talent <Protection of the Mind> so he asked again without the previous urgency. In any case, the side effect has already happened. He may as well try to think of a solution if it's bad rather than worrying himself over it and there's always the System as a back up if he ever needed it.
[As <Avalon>'s holder, Master has gotten the side effect of eternal youth which mea-.]
Gaia didn't get to finish her sentence before getting interrupted by her master.
"Ah, you don't need to explain anymore Gaia. Thank you, I've already got the gist of what you're talking about. Though you say eternal youth, what you really meant was that having <Avalon> prevents physical deterioration and so my appearance will stay this way forever, right?"
Now that his mind was cleared up, Zero was able to think things through more thoroughly and it became easier for him to figure out what Gaia was talking about and recall what he knew about the legendary scabbard and what it did to its wielder.
The teen didn't mind though as he was satisfied with his current appearance and height. He was already 19, and it wasn't like he was going to get another growth spurt, though the same couldn't be said for <Avalon>'s original wielder, Artoria; the poor girl.
[Yes Master, but can you please not interrupt next time? If not, Gaia will be angry.]
The fairy pouted with puffed cheeks and had her hands on her hips as she floated in front of Zero to express her dissatisfaction; the teen could see her two sets of beautiful fairy wings flapping furiously behind her which further indicated how displeased she was.
"Right right. Master will definitely pay attention next time, don't you worry."
Zero hastily said to appease the loli and even spoke in third person as if he was talking to a child. Inside his mind though he was beginning to sweat bullets as he was afraid he would start developing a certain trait due to how cute this girl was. Hell no was he going to be a lolicon.
The teen liked busty beauties with 'all them curves in all the right places' and although his System Fairy was indeed developed in the chest department, it didn't change the fact that she was a little girl.
After pacifying the fairy's dissatisfaction, Zero decided to return his sword and scabbard back into the Inventory and bring out the remaining item left in it as Gaia stayed floating off to the side.
There was no point in pulling out the sword because he wasn't going to use it for anything at the moment. As for checking it's appearance out of the sheath? There's plenty of time in the future.
As he willed for both <Excalibur> and <Avalon> to move back into the Inventory, the Noble Phantasms shined a resplendent golden light that made our protagonist have to close his eyes due to the sheer brightness they were emitting. Gaia, on the other hand, was unaffected by this.
When it all calmed down, Zero opened his eyes which displayed confusion when he saw that both armaments had disappeared. It wasn't just from his hands; no, they were also missing from his Inventory, was what he had noticed.
"Um… Was that supposed to happen?"
He blinked, asking subconsciously.
[If Master is wondering where <Excalibur> and <Avalon> went, then he should check within his mindscape. Master only needs to concentrate his focus on the connection between himself and the two Noble Phantasms and he will naturally appear there as well.]
The fairy quickly explained, realizing her master's predicament.
Zero did what Gaia said and focused his sole attention on the connection between his recently acquired armaments and himself. <Protection of the Mind> helped him a lot on filtering the unnecessary thoughts in this situation which made it easier for him to calm down and sense the connection faster.
Soon, the teen found himself appearing in a space surrounded by a dark void with the only light source being the two things in front of him - his sword and scabbard.
He had indeed found where <Excalibur> and <Avalon> were, just like Gaia had said he would.
"There you ar- Eh…? Is this what my Inner World looks like? How come there's nothing but void?"
Zero thought aloud as he looked at his surroundings. That was when he heard Gaia's sweet voice mixed with a bit of exasperation resound within his consciousness.
[Master, you should know by now that you are also able to adjust your Inner World according to your own preferences, with just a single thought... like everything else so far...]
"Oh, right. How do I keep forgetting this simple thing?"
Zero frowned. He would usually notice things like this quite quickly. What's wrong with him today?
[It must be because Master is tired.]
The fairy comforted.
"Ah… yeah, perhaps that is so. I mean, technically, I haven't slept for over a year now."
Zero nodded his head as he recalled what the god had told him after transferring all his powers to him; apparently it had taken a year to do it.
"I have decided. After we have entered a world, the first thing I'm going to do is take a big fat nap."
The raven-haired teen declared to the air. He didn't exactly see Gaia anywhere, but he was certain the little fairy could still hear him.
"But first…"
He continued while his gaze remained on the surroundings.
"... let's change this place up a bit, shall we? Pains me to leave it so dull."
And so, with a single thought, Zero had turned his Inner World into a vast expanse of land, sea and sky with a bright yellow sun shining down on everything.
Below him was the line which divided the grasslands and ocean and above him was the expansive blue sky; all three of them seemed to stretch infinitely and under no circumstances was one able to see the end.
Zero, on the other hand, was floating in the air with his two armaments. The teen was able to do this due to this whole area being his Inner world and here, he was literally God. It was definitely a fresh experience for him.
"Now that's more like it. Everything has brightened up compared to the endless darkness before. The infinite space gives people the feeling of eternal freedom, just how I pictured it to be. So what do you guys think? You like the change to your new home?"
Asked Zero towards <Excalibur> and <Avalon> who were hovering alongside him. He wasn't exactly expecting a response and was astonished when both gave off a glimmer of light as if in acknowledgement of what he said. He could also somehow feel that <Avalon> was genuinely happy while <Excalibur> on the other hand had hmmph'd at him.
[Master, sacred armaments like <Avalon> and <Excalibur> possess their own spirits so they are naturally able to understand your feelings just as you are able to understand theirs; this is due to the connection Master has with the both of them.]
Gaia explained as if noticing her Master's surprise. It was unknown when, but Gaia had reappeared sitting on Zero's head again.
"Really now... How interesting."
The raven-haired teen thought aloud.
[Mn! Armaments that possess their own spirits are also very intelligent, which makes them harder to wield if the holder hasn't gained their acknowledgement. While <Avalon> is a relatively gentle spirit and has already recognized Master as it's master, <Excalibur> on the other hand is much more prideful. Although Master would be able to wield it just as any regular sword, <Excalibur> won't allow you to use it's Noble Phantasm until Master is strong enough.]
"Haha, that's to be expected. If I was <Excalibur>, I definitely wouldn't want to be wielded by someone lacking in strength, let alone allow them to use my ultimate ability. It's pretty normal, no? But don't worry, I'll get you to acknowledge me soon, little guy."
Zero laughed as his gaze landed on his two Noble Phantasms; more specifically, his eyes were locked onto the hilt attached to the scabbard.
'Shiiinng'
The Sword of Promised Victory gave a noise in protest like it didn't believe him. The teen didn't mind and just smiled slightly.
He was a Saiyan; there were plenty of ways to grow stronger fast. Although some of them involved breaking bones, tiring himself out or even going as far to the point of experiencing near death, Zero was still willing to try.
The teen had <Avalon> as backup in any case and if it really came down to it, wasn't there the System? It definitely wouldn't want it's creator's successor to die. Maybe the System wouldn't directly help him, but it would at least warn him if he ever goes too far in his training.
[A reminder to Master. The <Avalon> and <Excalibur> in front are different from the original as they are special armaments called <Growth Armaments> which grow stronger according to the wielder's status.
To wield <Excalibur>'s Noble Phantasm, Master probably needs to finish laying his foundation first. This means that Master has to go through Level 1 and Level 2, which are the two foundation realms, before becoming strong enough to become a Super Saiyan at Level 3.
It is only from then that <Excalibur> and <Avalon> will become stronger along with Master as they are only armaments at the 2nd Mortal Realm level at the moment.]
"Eh… growth weapons are nice and all but... strong enough to transform into a Super Saiyan? That might take a while… Well, whatever, no use fretting over it."
[Mn, Master has a lot of time, hehe.]
Gaia agreed with a chuckle.
"Yeah yeah, I know. Well, I think it's probably about time we get out of here. As for the two of you… "
Stated the raven-haired teen to his System Fairy before putting his attention back on his Noble Phantasms.
"... I've previously mentioned this to Gaia and I'll say the same to you. You're probably going to be stuck with me from now on, whether you like it or not, so I hope all of us are able to get along with one another. I'm going to be relying on you guys a lot in the future, so don't let me down and I will do the same, alright?"
<Excalibur> and <Avalon> flashed a golden light in response to that.
Zero smiled after getting the answer he wanted through the feelings they had given him through their connection.
"Alright then, let's get going."
[Yes, Master]
And with her reply, they disappeared from his Inner World.
