I nodded back, "Lindy-san. I am here to propose a mutually beneficial agreement."

0065 - December 1st

TSAB Ship Arthra

She raised one eyebrow at my words. "Mutually beneficial agreement?"

I nodded. "Yes. From what little details I know about TSAB, it is a law enforcement organization of multiple worlds. But to what extent I do not know (All I know is Mid-Childa)." At her confirmation I continued, "And currently, you are on a mission to deal with certain law-breaking group. One which on the opposite side of the battle I participated earlier."

"That's more or less correct."

"You are in a quite tight position, where you operate with limited resources. At least two of your personels are not combat-ready for several days. On the other hand, this group may or may not have reinforcements."

"Also more or less correct."

"I am offering you my service, an extra pair of hands if you would. However, there are things that you may not and will not tell me. And there are things that I will hesitant to tell you (like how I know that Hayate is the Book's master because I watched Nanoha series). However, I swear that all I am going to say contain no lies."

She nodded at my second sentence, and raised an eyebrow at my third.

"I... am not originally from this world (I reincarnated). I came here because of an time-space event that I don't understand myself. My previous world (Potterverse Earth) was a world where the magicals are hiding from the mundanes. There was something like a witch-hunt, where the suspected magicals were executed by mundanes, several hundred years back in the history."

At this point her eyes widen.

"The separation became a problem after quite some time. The magical societies became stagnant while the mundane had made progress in various field of technology and science. Moreover, the magical societies are very prejudiced, especially for the blood status. There were several categories of citizen, The pure-blood, the half-blood, the mundane-born magical, the magical-born mundane, and the one with creature inheritance.

A pure-blood is someone with two maternal and two paternal grandparents. A half-blood is someone with at least one magical grandparent but less than four. A mundane-born magical is like the name implied, born from mundane lineage. A magical-born mundane is someone born from magical lineage, yet unable to perform magic. Creature inheritance is also as the name implies, at some point his or her lineage united with other humanoid magical species. For example, succubus or siren.

The governments treat their people in that order, so a pure-blood is a first-class citizen, half-bloods are second class, while the last three are the lowest class citizens. Sometimes, the ones with mundane lineage or creature inheritance unable to use their rights, simply because the pure-blood said so. The mundane-born magicals often disowned by their parents.

Several circumstances in magical societies which including, but not limited to, civil war and inter-magical-species war, led to death of many magicals. At some point the pure-bloods became so inbreed that it's so sickening. They tend to keep their blood 'pure' and since there are so few of them, their marriage became so close-knitted. It did not help that most of them only had two children per family. There is at least one family that keep the tradition of sibling marriage. For several generations the brother would marry the sister like their parents did."

There, that's a summary of one of countless many Potterverse world. It was so damn hard to said it all in professional tone.

Lindy-san knitted her eyebrows, trying to digest my information. Her face displayed mix of disgust and anger.

"I happen to be a magical from mundane birth (no magic in my old world). At some point I felt sickened by the society. And by chance (reincarnated in Potterverse and abused Room of Requirement), several years ago I found (asked for) a device, which I believe that's how you call your foci. That thing was not compatible with me. I spent a lot of time to reverse-engineer said device and made Eyaruu-"

I raised my right bracer and it gave a ping sound.

"-by combining my world's magical theory and your technology. It might not be the best since there are things that contradictory, but it's usable and useful. And then I got involved in said civil war (not just involved, I either ended that damn thing or made it even bigger). I ran away, then the time-space event happened. Next thing I know, I woke up in this world," I ended my story.

"That's quite a story you have there, Will-san. And pray tell, what kind of payment you ask in return?"

I give a weak smile.

"Two things actually, a transport and an equivalent of recommendation letter for me to apply a citizenship in one of your worlds."

"That's it? It seems... very cheap for a self-proclaimed mercenary,"

"Lindy-san, I am practically stranded and stuck here. My device has no coordinate records of other worlds. While I have no desire to go back, I do not want to spend my entire life here. So, unless you give me a lift, I would resort to a less... legal method of travel. I have some experience in less... legal administrative procedure, since I did forge my identity here. A feral wolf that you can see is less dangerous than the one you can't see, isn't it?" I ended that with a smirk.

She smirked back.

"And depending on the impression during my stay, I may join the TSAB in the future. A pair of able hands are always welcomed in either sides, yes?"

The discussion went for a little while. It was until a certain point Chrono and Amy opened the door and enter the room.

The first time his eyes landed on me, he practically shouted.

"YOU!"

I ignored him and paid attention to Amy instead.

"Hello, Miss." I greeted her when she came closer.

She returned my greetings, Chrono was growling, while Lindy-san was torn between disapproval and amusement.

"Do not ignore me!" Chrono half-shouted in anger.

I turned my head toward him. Channeling EMIYA, I said, "Sorry, but I don't swing that way."

Both females smirked. Chrono spluttered.

"There were two cute girls that downed. Between them and you, it is obvious that I will choose them over you," I said riling him up.

He was nearly frothing

"Let's use this as comparison, shall we? Two people, one grandma and one male your age. Both were bitten by poisonous snake on the thigh. I am not sorry to say that I will choose to save the old grandma. No matter what you say, I will not put my face near another male's crotch."

The proverbial crack could be heard and he experienced meltdown-

"Do not use that as comparison, damn it!"

-and proceeded to exit the room in tantrum.

Both females were unable to decide whether the want to giggle or frown.

And when they finally collected themselves, my reply to their question was a simple yet complex one.

"Looking at him, I can see someone who's very serious and dedicated, despite his young age. However, from another perspective, he does not seem to have enough social interaction with teens of his age. I was trying to make friends, but I do keep my image."

"That's a pretty roundabout way to make friends," Amy said wryly.

"Say what you want, Miss. But friendship among males is different from friendship among females. We do not spend our time shopping, gossiping, or eating cakes. And friendship among males may include some strange things, but not limited to, rivalry, sharing extreme hobbies, giving insulting nicknames, rude languages, brawl, or even trading porn collection." I looked at Lindy-san and she reluctantly nodded at this.

0065 - December

Uminari City

The world moves on without-

Whoops. Wrong story.

But it no less true, over the next several days people came and people went, spending their time in their own business. And that was about the same length of time it would take for Nanoha to recover.

I did not know how long did she recover from drained (stolen?) core in anime. Yeah, either the date was not listed on my copy or I did not pay attention to it back then. It took several days for her core to recover, but she was able to do anything non-magic during her recovery time.

There was also problem with their devices. They both damaged, badly. I did not know how long would it take to repair them both, since I did not meet the device meister staffs. I also did not remember when both devices would be fully repaired and upgraded in anime. My expertise (supposedly) also could not be applied here. I specialise in my kind of device, Tha'an-dahryuun device, not Mid-Childan or Belkan device. I only knew for sure that when those two asked for cartridge parts, the Wolkenritter would attack shortly after.

And so, I tried to spend these days productively. I pulled out my weighted clothes from Inventory to renew my physical conditioning. A little more mana to reapply the enchantment because it's not Potterverse.

I also meditate to recheck my mental augmentation. It seemed that my Memory Partition and Mental Acceleration need some fine tuning. Me reverted back to 13 years old and stuffs.

Meditation also helped me regulate and fine tune control of my mana and ki. Nothing much, just to have better grasp on the quantity. You couldn't quantify something within you without external help, a measuring equipment. However, you could divide it, grab a fraction with error range of certain value. The better your control, the more precise that fraction, and thus, the less you waste.

I also brainstormed, preparing for that damned Book of Darkness, the corrupted form of Book of Night Sky. There should be a way for those poor guys to have a good ending. No, no. I would not kill Hayate or the Wolkenritter.

Okay, only NatchWal, the automatic defense program. The Darkeness of Book of Darkness. A planet killer Lost Logia.

Come to think about it, that damned program was able to regenerate. It didn't matter that Nanoha and co nuked it to kingdom come with Triple Breaker, Rein in anime said that new program would regenerate in... what was it again? 24 or 48 hours?

That was the reason she sacrificed herself, wasn't it?

If, and only if, that regeneration could be halted. She wouldn't need to sacrifice herself, right?

But what could I do?

I was on my way back to my hotel when I heard someone called me.

"Umm... William-san?"

I turned and saw a blonde girl with twin-tails, Fate. The girl who would be Nanoha's lesbian partner in the future. Or not?

"Fate, right?" I asked, as if I did not know her.

Of fucking course I did not know her. I was just know about her.

She nodded and I continued.

"Call me Will, William is too mouthful. Feel free to not use the honorific if you want to. So," I put my hands together and emulated the expression of merchant NPC from certain game, "what do you need?"

She furrowed her brow, not getting the reference, for a few moments before continuing.

"Ah.. I just wanted to thank you for saving Nanoha-chan."

"Nanoha? The one with pigtails?" I continued to act.

She nodded.

"Well, I did it because... I wanted to, I guess. Like I said, I was just gotten lost on the road of life."

"Well," she put a strained smile, "your actions meant that she was only out for a few days. So, thank you."

I waved my hand off, "It's fine. Don't over-think it."

She smiled.

"And by the way, you are the first person who approached me since then."

"Eh?" she asked, wide-eyed.

"Because, you know... I shouted out loud after Nanoha shot that pink beam. Everyone have been giving me weird look the entire time." I said, closing both eyes.

She was not able to form coherent sentence.

I opened one eye and looked at her blushing face, "I am not sexually harassing you, you know? Like I said, I am not into non-consensual sex or child molesting."

Actually, that was a sexual harassment.

Fate made more non coherent sentence. It made me wonder, just where the hell did 9 years old girl learned about sex education. She recognized those terms.

It took several minutes before she collected herself.

*cough!* "By the way, TSAB is offering you a temporary commission, just like Nanoha and I."

I opened both eyes and raised one eyebrow. "I thought they already did. Me being a mercenary and things."

"Ah, it seems they want to formalize the deal," she said with a little shrug. "Something along the lines of 'potentially powerful asset'. Well, at least until the threat is neutralized."

Wonderful. Integration step one completed.

"'Until the threat is neutralized?' You make it seems ominous. I haven't exactly briefed about this 'mission', you know?"

"Eh? You haven't?" she asked surprised.

"I did talk to Lindy-san that there are things that she may not and will not tell me, and there are things that I will not tell her. Basically, there are secrets that we keep from each other."

I paused for a moment before continue.

"And since the briefing seem to have happened before my commission formally declared, it's quite logical that there were sensitive information covered in that briefing that I am not yet allowed to know." I shrugged, "Me being extra muscle and all."

Fate made an expression that I was not able to recognize.

"So, we do have more problem than four-men, possibly more, law breaker group?" I asked, still in my act.

She hesitantly nodded.

"Well, just tell her about it. Ask her what kind of information you are allowed to tell me. If the deal is real, then either you tell me or she may ask me to come and tell me herself."

There are many things to do, many things to prepare. We were going to fight against a planet killer somewhen before winter end. It could be a month, it could be two.

We were going to fight a planet killer, we would need any advantage we could get.

A/N: Here's the fourth chapter. I portrayed Lindy as someone who, while gentle, do enjoy some mischief once in a while (like at the beginning of ep 8 season 1). Of course she's both a competent officer and mother. It was Hayate who often plays prank to others. Amy also enjoy some mischief like when she bandaged Chrono's head (ep 13 season 1).

Thanks for your support and please review.

Until next time.
