After terrorizing almost everyone there at Nanoha's parent's café; Yu, Lindy, Nitoh, Chrono, Yuuno, and Fate returned to the apartment complex that the two adults managed to set themselves up at.

As soon as they got to their apartment they discussed over what will be happening, apparently Fate will be going to school along with the rest of the kids while everyone else will be investigating the Knight's whereabouts and possible target to go after next.

Meanwhile, when Yuuno and Yu were discussing over what has happened so far with the encounters with the Knights, Yu was rather shocked that apparently during Yuuno's fight with one of them they were going behind their master's back to do something.

He also remembered the expression that Signum had over fighting to do what they were doing behind their master's back. And that led to Yu curious about the circumstances, in the Jewel Seed Incident there was a mastermind behind the whole situation.

Not only that but Fate was used as a pawn and tool by her mother, it was something that still angered her to no end, thankfully she's been fixed up and then sent to go under the custody of the G-Men till she was later sent to one of the TSAB controlled planets to undergo psych evaluation and incarceration for her crimes as well.

So judging from what Yuuno said about the situation at hand, it felt rather off to him and there is surely more to the story at hand here then what was said to be known about them. He just knew in it his hear that there is more than meets the eyes about the Book of Darkness incident, and he planned to find out and prevent the worst possible conclusion to it, because that is his pride as Kamen Rider, and as the one who will become the Final Hope like his father was before him.

All those thoughts went out of his mind when he heard the door creaking open, knowing who would do something like this and without any hesitation he moved to one part of his bed to allow the Fate in.

The blonde girl looked sad and happy, happy that she is next to Yu; but sad over having the nightmares once more. Yu hated that, he hated seeing his loved ones and friends sad, they should be happy enjoying life, not suffering what appears to be trauma from the past.

Fate looked extremely grateful to him as she whispered a rather quiet thank you to him, as she laid next to him. Yu can only smile warmly at her. "Get some sleep Fate we are going to school alongside Nanoha and the rest of the girls, you will need your rest."

Fate could only smile softly at him once more before snuggling closer to the boy. It has been barely a minute since she climbed into bed with him and she's already sleeping like an angel. Yu then decided to follow her example, with all the new powers, homework, and threats with the Knights. He will need all the sleep he can get.

But before he fell asleep he remembered one important conversation he had with Knight during one of their meditation and training sessions.

'Yu.' Knight spoke up in his mind interrupting his concertation levels right now. He quickly paid attention to what Knight said as he spoke with a melancholy tone in his voice. So that means whatever he had to say is rather life changing or some words of wisdom to go by.

'What is it Knight? Is something the matter or something like that?' Yu thought as he was curious as to what he is thinking right now.

'No nothing like that, it is just I hate the rain a lot.' That took him by surprise as Knight would never have an irrational hate for just about anything unless it offends his nature or pride.

'It is not because I hate it for any weird reason or anything like that, it is just when you are a beast full of emotional power, your emotions influence how the underworld is like. I hate rain as it is sad and painful. It rains in here, too you know? When you are moody, it becomes cloudy. When you are sad, the rain comes down... I can't stand it at all, I cannot stand you being in despair. Can you understand? How horrible it is to get rained on when you are all alone in an empty world? In order to prevent that from happening... I'll lend you whatever power you need! If you can trust me... I won't let one drop of rain fall from that sky! Trust me... you are not alone in battle...Yu. For when you enter the battle I am always at your side, with providing you with magic and the forms needed to evolve, or just giving you advice.'

Yu was shocked at what Knight has declared, he basically wants him to use him to do what is necessary in his life to prevent those rain of sorrow, and he wants him to believe in him. He could only say one thing to him.

'Of course Knight, I will believe in you as you for me, so won't you let me believe in you as well? Even when there is no God or Buddha there is always us, Kamen Rider you know?' that caused Knight to roar in laughter and approval at his words.

Thought he did not managed to get much done, he felt he learned something far more valuable on this day. He had insight into his Phantom and learned more about how different he is from other Phantoms his parents had fought over the years in their career.

Now remembering what was spoken during that conversation and what Fate and Nanoha have been through just recently, he made a vow to stop the rain of sorrow from falling on them. Yu then yawned then fell asleep for the night with Fate.

"It has been a long time since I was last in school." Yu commented as he, Nanoha, and Fate were walking to their school all dressed up in their uniform and the likes. The other two girls could only nod at this odd thought of Yu.

For Fate, she looks fine on the outside but she was a nervous wreck on the inside, this will be the first time she will interact with other people her age besides Nanoha and Yu. And unlike Nanoha, she has no comfort about opening up to anyone, she just finds it hard to do at times really, due to her lack of social grace.

It was also exacerbated by whatever her mother has done to her as well, living with a cruel maniacal woman whose only goals are to resurrect her dead first child while being ordered around like a tool does absolute horrors to her socializing abilities.

But nevertheless, Fate had an easy time adjusting to class, she is just simply overwhelmed by the many people and questions that were asked during her presentation. It has gotten the blonde mage pretty overwhelmed that she ran over to Yu's desk and started holding his hand for comfort.

Everyone were surprised and suspicious of how this went till Yu out it all to rest. "Fate has some Social Anxiety issues, as it turns out she gets overwhelmed by crowds easily. And she is holding onto me because I have been one of her longest friends." Yu managed to say it without much issues save for the raging blush on his face; which ruined his serious expression a lot.

That calmed everyone down a bit, but the three girls in the know had their own thoughts, Alissa found this to be a point in Fate's favor for winning Yu's affection. Suzuka thought it was adorable and hoped Fate could get better at this. Nanoha was pouting at how close Fate was to Yu but understood the reasons, so she let it go. That doesn't mean she had to like it though.

By lunchtime the four girls plus one friend all met up around their usual meeting place. "So girls did anything interesting happen while me and Fate were away?" Yu asked the first set of questions as he wanted to catch up on everything he may have missed over his time with aliens of sort.

Alissa then spoke up. "Well Suzuka and I made a new friend at the library during the time you were out. She was pretty nice and chipper for someone who was handicapped as well." That caught Yu's attention there, since there is only one girl he knew who was like that.

"Question Alissa." Catching everyone off by surprise. "Would this girl happen to have brown hair and is named Hayate?" That caught Alissa's attention as she nodded in in reply to that. "Figures, that one of Nanoha's friends would meet one of my few friends as well."

Everyone besides Nanoha and Fate looked surprised at that coincidence, as they compute the thought of Yu having any other friend besides Nanoha before the Jewel Seed Incident. Which in his case makes sense, as there are few people that Yu ever willingly open up to talk about considering his lot in life is to stem the darkness of the world.

"Wait you know her Yu." Alissa asked rather incredibly, considering the fact she never saw him interact with others save for them. Yu nodded in reply, "I know her quite well actually Alissa. She can be considered to be my second best friend and someone who is quite nice to talk to as well."

Then his eyes turned sad when he continued on. "Many years back a long time ago, Hayate's parents died in a car crash." Which caused all the girls to gasp. "That car crash not only left her alone, but it also deprived her of her ability to walk as well as you may have noticed. Worse yet, is the fact that ever since I met her, she has been getting weaker physically over time and the doctors don't know what is going on for this situation causing it."

All hail Yu! Master of destroying good moods everywhere right now! "Of course even when she gets weaker almost every year or so. She has always been positive and kind to people that deserve it. Furthermore couple weeks back before the Jewel Seed Incident started, she gotten some new relatives and family. It is something that I am quite grateful for." Which thankfully brighten the mood of everyone there.

"She sounds like a great person Yu, is there anything else you could tell us about her?" Suzuka asked, quite curiously about the friend that Yu had and the new one that she and Alissa made. Yu then stopped smiling and put his hand on his chin as if thinking of the possible choices to answer.

"Well if there is one quirk that I am completely sure of about Hayate, is that despite being nice and all. She is very much a covert pervert." And like that, everyone who was listening all faceplanted or sweatdropped at such a weird description.

"From the stuff she read, she generally goes for the harem, ecchi, and perverted stuff among the manga content that she occasionally buys. Not only that according to her caretaker Miss. Hilda, she gets very touchy-feely whenever she's in the bathroom or in the bed with Hayate."

Now turning to the other people around him. "Not only that but she is very much into cosplay, and is a superb costume designer of sorts as well. She likes making cute designs and having people try them on from time to time. I myself have done it multiple times with her, as I am kind of the only guy she knows and is also willing to do these favors for her as well."

When Yu finished his explanations, there was a disturbing sort of gleam in Nanoha's and Fate's eyes as they slowly approached him. Yu felt a rather disturbing vibe coming from them, and his instincts were shouting at him run away.

"So Yu, you were into what was it? Cosplaying was the thing that Hayate had you do from time to time?" Nanoha asked with that rather disturbing look in her eyes as she and Fate slowly approached Yu. Yu now knowing the trap he walked into could only sigh and nodded at his fate.

Then Nanoha and Fate got a strong sparkle in their eyes as they grabbed his arms. "So does Hayate take pictures of it? Does she have it available somewhere? Can she give us some pictures of it? Will she let us have some of its contents?"

Yu could not answered as he was being shaken constantly by the two girls, and the other two, curse them and their need for entertainment, decided to just let it go so they can laugh at the situation. He knew that this school day was going to suck till he decided to treat them to close quarter combat training, unfortunately that is going to take a little while to do.

After managing to shake off Nanoha and Fate's weird obsession with him in cosplay, and after school has ended. Yu decided to take them to train for the melee fighting. But to make everything fair since they don't have their devices ready as they were still undergoing renovations still.

He had them and himself use wooden words from the dojo that Yu frequented with Nanoha's older brother, and for now this will be good enough till they train up with their devices. Needless to say due to Nanoha and Fate's overreliance on spells they neglected their own body training which became evident when Yu was winning without much trouble on his part.

He had them alternate with him so he can assess their skill set and how much work they needed. The results were not that pleasant as it turns out while Nanoha and Fate were fit fine normal people, they did not have the toughened body that Yu and many Kamen Riders had.

So he set out a work out plan to get them in shape or close enough, as "A healthy mind comes from a healthy body." Yu spoke to them and by pushing their physical limits it should be easier for them to work some of their spells as well.

And then after that he let them rest for a bit and then goes straight to sparring with him. Needless to say he managed to get back at Nanoha for using him as target practice for her S class bombardment level spell in preparation for her second duel with Fate painfully.

By the time the training session ended, Yu was left rather very content and smiling all the way while the two girls were groaning from all the pain that Yu put them through. But they have developed a stronger respect and love for Yu now knowing what he does to make himself stronger and better.

If this is what he did every day to better himself to catch up with them then Yu has been pushing himself harder than the two girls do for their spell training. And seeing that level of dedication and experiencing it for the first time humbled the two girls as they kept up this training regime.

When they got back, naturally Nanoha's father was angry beyond reason and it took Lindy, Momoko, and Nitoh's combined efforts to stop the super overprotective father. When he finally calmed down, he quickly became enraged when he found out that Nanoha fell deeper in love with Yu. And this time, Nanoha and Fate had to step in by using the dreaded foes of adults everywhere, the irresistible, adorable, sparkly, and sad puppy eyes to spare him.

So for the time being Yu managed to avoid being sliced to death by one overprotective father. Then Lindy and Nitoh picked up Yu and brought back to their place. There he found out that Chrono drafted Yuuno to become some sort of super librarian of sorts and found the needed data on the knights and their fighting styles and records of sorts.

"So these Knights are not actually people but constructs made by the Book of Darkness to act as the guardians to the master of the Book itself?" Yu asked in complete fascination of the Book's property, destructive it may be, but still doesn't take away the interesting features the Book has.

Lindy nodded in reply. "That is correct Yu, these Knights you and the girls fought are all based off of people that the Book of Darkness have encountered over the years, they are all very deadly as only the youngest of them has at least a hundred years of combat experience and the oldest is said to have thousands of years of combat experience."

Then Nitoh pointed to all the data that is known about them who then took control of the conversation, he then pointed to the woman with pink hair and pink armor. "Signum the Blazing General as you may have heard, is the leader of the Knights and the one with the most experience. The fact you came out to forcing her to a draw is a miracle by itself Yu."

Then he pointed to the blonde one in a green dress, "Shamal the Maiden of the Lake, from what our records and data indicates, she is a support class mage often focused on helping maintain their devices, healing them, and other such magical support and in terms of combat level she is low on the totem pole but extraordinary high on the support pole."

Then Nitoh pointed to the one in red with the pigtails and the hat with the bunnies on them. "Vita the Iron Hammer is regarded as the youngest but also the powerhouse among the Knights, so she is incredibly dangerous due to her use of such destructive spells and skills. Recommend extreme caution when dealing with her Yu."

Then Nitoh pointed to the last one which is a dark skinned man in dark blue with a dark blue wolf form next to him. "And finally this is Zafira the Shielding Guard Beast of the Knights. He has no such notable abilities save for being a master of close quarter combat level martial arts. And is the least magical of the lot, but still recommend extreme caution when dealing with him."

Now turning to Yu with a grim look on his face. "These are all warriors and/or mages who have pushed themselves in their dedicated craft to become the warriors that they are today. Given enough time they could take on Presea and win without much trouble, someone who you had a lot of trouble dealing with while she was sick, dying, drained from overusing her spells earlier, and needed you Blood Warrior mode to defeat. You sure you wish to take them on still Yu?"

Yu looked firm and on the inside he is very much resolved to walk the path that he truly believe to be right. So he could only nod and the two adults gave him proud smiles as he turned to inform Nanoha and Fate about the kind of opponents that they will be facing soon.

This will also be a great chance for me to test out my newest Blood Warrior form as well. And if what I remembered Knight said to be it should be an upgraded form of my Water form with a trident instead of the harpoon I typically use, should throw Signum off for a bit.

Though I do hope that the trap that the TSAB will be good enough, otherwise we will not be in a very good position. Their battle plan does involve me, Nanoha, and Fate as bait, then we try to stall them before Nitoh and the others come to back us up, then deal with the Knights of the Dark Book.

Nanoha will be taking on Vita, and Fate will deal with Zafira, and I will deal with Signum herself. This time, we will hold the advantage and Fate and Nanoha's Devices are upgraded to use the same system that the Knights use for their magic. So hopefully we will be even for now.

Nanoha, Fate, and I were waiting for the Knights to com and deal with us in the trap we set up. Yuuno would have come but he got kidnapped by Lindy and Chrono to become their official "Grand Liberian" or something like that; of secretive and long nature which I did not get.

The point is he is now going to be in the books for a while now. Nitoh was on standby to assist us in taking them down as well as taking down Shamal. As well as making sure that there was no interlopers out to prevent us from getting to the Knights and stopping the Book of Darkness.

The three of us were grim in our in preparation for the fight, I just hope this ends without any pain. Ah, it seems they have shown up now and not only that it appears they cornered a Fangire and ended it without much difficulty. Well it is Showtime now I guess, as us three leaped down.

As usual Fate and Nanoha were dealing with Vita and Zafira while I was left to deal with Signum. I must say despite the dangers and implications of what will happen if we fail, I am quite excited to fight her again as I equipped my Fire Blood Warrior mode on myself.

"It's been a while hasn't it Signum?" I called out to her and her eyes widened in recognition of me. But then shifted her expression to her neutral one as she blocked one of my many strikes from me with her blades. Then we were away from each other just staring each other down.

"Tis been a while as well young Rider, and it seems your skills have improved but won't you just let us pass and no else have to get hurt tonight?" her request was reasonable but unfortunately I had a duty to do as a TSAB junior officer as well. "Sorry I can't do that. I am obligated to stop you here Signum, but for now let our feelings flow as we clash with our blades Signum!"

She smiled approvingly of that train of thought. "Then prepare yourself once more young Rider, for you face the mightiest of the Cloud Knights!" then she dashed forward as I did too as our blades enter a deadly maelstrom of clashing blades as we each struggled to overpower over each other.

Then I swung around her then jumped to do a drop slash at which she blocked off with her sword but the pressure I put into my swing broke the ground beneath her and forced her back away which I dashed up to face her head on once again. Then when I got close I did a low spin kick which knocked her off balance and allowed me to inflict a stab mark to her left side of body.

Then regaining composure she grabbed the ground and spin kicked me into the ground face first. Then she called upon the power of her device and turned into a whip which surrounded my. Then she lifted me up and slammed me into the ground repeatedly till I force the chains to loosen and let me go. Then I light my swords on fire then bashed the chains away from me once more.

Then once the chains were away I used my teleport ring to dodge another slash attempt from Signum and get behind her, which she anticipated and I used both my swords to block her swing. Then she kicked me in the stomach knocking me back further away from her and I was breathing hard. Well now was the time to use that new power that I got now and taker head on once more.

I slipped off my Fire Ring for my Water ring and used and she paused as my new from appeared before me. Then a new magic circle appeared beneath me and surrounded me in the formula circle while emitting energy that prevented Signum from getting to close to me now.

Change Now! Blood Warrior! Water Drown, Drown, Drown, Drown, Drown!

Just like my Fire Blood Warrior mode was, it was the typical black bodysuit and the additional armor features which were all dark blue with aqua colored runes on my armor. Not only that but the horns that would be on my helmet were replaced with crab claws and my swords reconnected and shifted into the harpoon I would use in my water form. Then shifted into a trident which I grabbed as soon as I can then pointed it at Signum who was left dumbfounded at this incident.

Then I swung my trident for a bit, then charged at her which seemed to knock her out of her reverie and she retaliated as soon as she can. Now that I was in my upgraded water form I became more agile and acrobatic. Which I put to good use as I dodged all of swings and sped around her striking her with my trident.

Then I went for a stabbing motion which she cleverly blocked with her sword using the gaps on my trident. Then she spun around lifting my off the ground and kicking me in the back. Then when I got up she was a bit curious as to why I held my weapon still, guess she tried to disarm me then.

I quickly used my stretch ring to swing my trident at her and she was surprised by the ring's power then I dashed forward once more which using my liquid ring, just as she used a fire spell on me. Which was immediately dispersed as soon as it touched my armor which surprised her enough that she did not notice the trident being swung in her face knocking her back.

She quickly got up and we dashed once more into a calamity of sharp weapons she struck me in the side, I bashed her in her stomach. She tried to crack my head open. I blocked it then spin kicked her in the face then she punched me in the stomach pushing me away from her again.

Then she shifted her sword into its whip mood and swing it at me which I blocked with my trident, then the chains locked onto my trident trying to force me to let go of my trident. Then we were forced in a deadlock trying to force one another's weapon out of our opponent's hands.

I faltered first as my weapon was snatched out of my hands then thrown away from me. There was only one thing left to do now, I used my liquid ring once more than dashed to confront her. She tried to slice me, I turned onto water and then got on her then locked my legs around her.

She tried to get me off. I tried every unarmed fighting style I know on her head and was repeatedly punching her in the face. As she wobbled around struggling to get me off her. We struggled for a bit as she finally tripped and then I hit my head on the walkway weakening my grip on which she took the opportunity to finally get out and then get back to her sword device.

As she dashed for her sword that she dropped during my dealings in liquid form while I used the chance to grab my trident, which was close by, and then jabbed her with it as soon as I could. She was proving to be a very formidable opponent right now. I could not afford to lose here.

Then she narrowed her eyes at me as we clashed singlehandedly again. Through this duel of ours, I could tell that she did not want to do what she did. But she was willing to do it for the sake of someone else. In other words she was desperate like Fate was for her mother. But the question is why did they need to gather the energy and do it behind their master's back?

Either way, they were not going to get anything out of her or the other Knights till they defeat and put them into custody to start searching for their master. Even so Yu could not help but be curious as to what kind of person is their master that they are willing to do this behind their back.

"Say Signum what kind of person is your master for you to do this behind his or her back?" That took her by surprise as we were in a deadlock of our weapons once more, but her eyes softened a bit, which mean she obviously cares a lot about her to do what she is doing right now, that is bad.

Which means she is the kind of person who is willing to drench her hands in a lot of blood to save whoever she needs to protect her master, and the devoted ones are usually the most dangerous you can get. As their loyalty keeps the going on and on no matter what happens at all.

Then she leapt away from me and her expression was that of a resigned woman while also her eyes describe her joy as well. "Our master…is the kindest person we have ever met. She was the first to not treat us like tools but as people." So her master is a kind and compassionate girl.

"At first we obeyed her because she was the one to summon us." Then I noticed my hands were down as well. "But then we grew to care for her, grew to love her as she is one of us, and then when we found out that she was sick we had to do something. We who have been nothing more than tools finally had something worth fighting for. So for her sake we will drench ourselves in blood for her sake no matter what."

Now point her sword at Yu. "So for that very reason alone we will triumph here and return to our master. Our resolve is firm and steady can the same be said about you Warlock?" I was silent at this initially, mostly in respect for the kind of loyalty and determination that she had for her master's sake.

"Yes my resolve is firm and steady as well. Know this Signum you have earned my respect as a fellow warrior but I must oppose as the Book of Darkness cannot awaken and be used to destroy this world. There are countless lives at stake and for the sake of those lives I will win as well!" Signum was looking at me with respect as we prepared to fight again for each one's own reason.

But then I felt something slamming into my side as someone knocked me to the ground and sealed me away Signum was surprised and I struggled to look around to see a masked stranger around. Then he pointed to me saying "Magic to use." Then I noticed to my horror that everyone else was knocked out and in pain as well.

I could only come to the conclusion that this stranger knocked them out and had the Knights drain them of magic energy to power the Book of Darkness. Then I realized that Nitoh has not come to back us up and could only come to the conclusion that he too was knocked out as well.

Then the other Knights came up to me and was started the draining process, it was pure unadulterated agony as me and Knight were screaming and shouting in pain. Signum could only flinch at my pain with guilt in her eyes. The process soon left me whimpering as it went on.

Then the barrier broke forcing them to stop the magic energy gathering for the Book retreat and the stranger to vanish before us. I soon fell unconscious as I heard the cries from the other Enforcers trying to help us all. Damn it all we failed to stop them and now there is a third party helping the Cloud Knights out complete the Book.
