But when Solar heard those words, her eyes widened in shock as she already knew who that person was, but she didn't look at Mio because she knew how perceptive Yuki was so she just kept it to herself. Her reaction was already enough for Yuki to make a guess as to who it was or rather she already knew that the problem of being a Heavenly Demon was already resolved and that she didn't have to worry about Solar's daughter's future since it was already set.
"Well, judging from your reaction it seems that the problem of your daughter's smell is already solved so we don't have to worry about that anymore," Yuki said as she shook her head, but before anyone could react, she already chained up Mio with her Ice Chains before pulling her towards her with an evil smirk on her face.
"Now… I believe it's your turn now, my disciple. Care to show your Master what have learned over these 1,000 years? I'm expecting a lot from you because your test isn't going to be like any other one, I will be the one to decide if you really meet up to my expectations by fighting me with all you've got. Fight me like you want to kill me, that is the only rule… Do you understand, Mio?" Yuki said with an evil smile as she ran her gloved finger along Mio's chin before pushing her back to get some distance and get ready for the fight that she had been looking forward to the most since coming back here.
But her words sent a shiver down Mio's spine as she didn't expect that there would be no rules other than that, but she quickly composed herself by closing her eyes and taking a deep breath. When she opened her eyes, Yuki was not disappointed with what she saw, what she saw in those eyes wasn't the one she was used to seeing when Mio looked at her, right now there wasn't any admiration or respect in those eyes, there was only killing intent in them.
"Good… That is how I want you to fight, I want you to fight at your best! Show your Master that you are really deserving to be my disciple!" Yuki unleashed her Aura as she made herself stronger to the same level as Mio knocking everyone back. But Mio remained standing as she also unleashed her own Aura that clashed with Yuki.
"I'll do you the courtesy as I'll also use a Scythe…" Yuki said with a grin as she made a Scythe with her Ice Magic, but that wasn't all. She also made it stronger by planting thousands of Magic Circles on it to make it as powerful as Mio's, and without any hesitation, she threw it towards Mio's direction which she dodged by just a slim margin.
But before Mio could react to it, she saw her Master making a pulling motion with her hands, and she knew that she was in trouble at that point. But there was no time reacting and she just braced herself, but it did almost nothing as the Scythe easily pierced her body making a giant hole in her chest.
"I thought you better than that! Never look away from your enemies and always expect the unexpected!" Yuki said with a cold smile as she pulled her Scythe which made Mio come to her Mio took this as an opportunity as she then shot out hundreds of Fireballs toward Yuki while locking her in place with her Gravitational Magic ensuring they hit her.
"Not bad, but you must do better than that~." Yuki shrugged it off as she kicked Mio just in time before snapping her Scythe into two. She then easily deflected all those hundreds of Fireballs.
A heated battle then came to the two and even though from afar it seemed that the two were relatively of the same strength as they traded blow for blow, if someone were to take a closer look at it, the severity of damage on Mio's body is a lot worse. Her words were much more severe as there were not only cuts on her body, but they were deeper than Yuki's, and probably the most severe wound that Mio had was the giant slash in her arm that made her bone already visible to everyone.
However that doesn't mean that Mio hasn't landed some good hits towards Yuk, she still managed to land some good hits on her, and the most prominent one was the slash on her back. But even though the two have such devastating wounds on their body, the two of them didn't stop at all. It didn't even look like they were feeling any pain from it and just continued like a madmen.
"Use your Memento Mori and don't worry about the consequences! I already altered that Skill of yours temporarily, I really want to see how powerful you are." Yuki challenged her while she summoned Thousands of Ice Daggers and controlled every single one of them to attack all simultaneously to attack Mio shocking everyone as none of them expected this kind of Skill to come from her.
Controlling multiple attacks was already hard enough and even seeing someone control just a dozen of them already seemed like a god-like power, that is also why they were so impressed earlier when they saw how the Ice Swords danced earlier when she was killing all of the Monsters beforehand. But it seemed that she was the real Monster as they couldn't even fathom how her head wasn't exploding from controlling so many things at once.
"It's only natural to be shocked… Because right now, Master is probably using about 75% of her real Battle Prowess against Lady Mio. At her peak or rather when she is really serious, she can control Millions of those things all at the same time." Chisato explained that she made a barrier to protect all the people, and she knew that the real battle was about to start now since Yuki was basically telling Mio to no longer hold anything back.
"Memento Mori: Infinity's End!" Mio snapped her fingers and used her time-stopping ability and destroy all of the Ice Swords that Mio just created before setting up for another attack.
"Memento Mori: Domain of Despair~" Without any fear at all, Mio sacrificed more than 200 years of her lifespan for this very single moment as she knew that with this she could finally go all out with this battle, something she wasn't able to do because all of her Origin Skills are simply too reckless and have powerful backlashes against her making it so dangerous for her to use.
"You little shit… You actually siphoned my power." Yuki cursed as she felt herself getting weaker and she knew that if she hadn't revealed earlier that she was a Beast, there was no possible way that Mio would set this Domain up because there was no possible way of her knowing that she was a Beast and setting it up would be useless because it only works on Beast and Monsters.
"Well… Master said that I can bring out all my cards, so that is what I'm going to do… Memento Mori: Flames of the Shattered Queen." Mio said with a sly smile as she ignited her Scythe with pale blue flames and when Yuki saw it, she was a little shocked as she didn't expect to see a Cursed Flame in this world.
But she just stayed silent as she cracked her neck before finally taking this seriously, if just before she used the Scythe on Mio to prove that she was still better than her in-weapon Master, now she can't be too reckless as a Cursed Flame can actually inflict some real damage to her body.
"I'm sorry, Chisato. But I'll refrain from using you for now since that would be too overkill. So I'll use your little sister for now." Yuki apologized to Chisato before bringing a pure white Sword out of thin air, but for some reason, all of them felt an ominous feeling about it, especially when they saw the chains surrounding it.
"Break free… my Heaven Devouring Sword." Yuki said as she broke off the chains from the Swords and unsheathed raising it powerful aura that hit everyone, and all of them felt their bones cracking because of it, even Chisato wasn't left unescaped as she also felt it in her body."
