Harry Potter, pushing his trolly through the crowds, was careful about activating his Byakugan. It's not that he wanted to use it, he really did, but he was careful about abusing it. To him, it was just another too, a unique tool yes, but it a tool and not the be-all-end-all of every discussion. Considering he still needed help in illusions, activating his Sharingan, possibly finding a way to counter the effects of the Mangekyō Sharingan induced blindness, and learning to use Swift Release, not to mention finding more information about the Rinnegan, the Tetseigan, and the Ketsuryūgan, he had a lot to deal with.

'Ok, first thing I need to do is practice Swift Release, seeing how it speeds up the body, having the Sharingan active as well should help negate the negative effects of having to force your brain to act faster than normal by perceiving things at a faster rate naturally.' Harry thinks, going through what he knows about how Kekkei Genkai.

'That means, I'll need to be placed in a life or death situation out of my control, then practice it until the third stage activate. Swift Release should technically be easy, just spread the chakra throughout the body, but evenly to avoid one part being faster than any other.'

Upon seeing that there was no platform 9 and 3/4, he removes his glasses to act like he was running his tires, and just for a moment, activate the Byakugan.

'As I thought, hidden, it appears to be an illusion, might as well go through it.'

Harry's POV

Seeing the Hogwarts Express, all I can think is wow, and beautiful. I also take a quick check to see that my backpack was still in, I still need too read the Dovahzul book, and as a new language, I'll need to be careful. If it is a magical language, them going around and speaking the words might cause problems, but practicing their writing, but if it is instead a written magic, this will be interesting.

Pulling my trunk onboard, I find an empty compartment to just read. After a clever use of chakra to temporarily increase my strength, I get my truck stored overhead. Placing my bag right beside me, I pull out Dovahzul and start reading

'Dovahzul is the language of dragons. Each word needs to be fully understood for it to be used in a Shout, or Thu'um. From there way it is spoken, to the way it is written, to the way it draws your power. When such a thing is understood.'

'Most of the time, a Thu'um, or shout, is composed of three words, each one empowering the word before it. Take for example, Unrelenting Force, the word are Fus Ro Dah, or, Force Balance Push respectively.'

'It takes a lot of study and repetition to fully master one word, so do not be discouraged when you cannot get the most simplest word just yet.'

'It should be prudent to add that there is a specific type of person who can use the Thu'um instinctively. The Dovahkin is a rare person who needs the soul of a dragon to unlock using a Thu'um, or have a person willingly share their knowledge with him or her. Such a being of very rare, and if found, is capable of great destruction and healing.'

I had to stop, and reflect on what I know. 'Learning this language will be hard' I think, and look out my window. 'I'll need time, and space, as well as a lot of writing. The Sharingan does have the capability to copy things, but this would be one of the two things they can't copy exactly, a clan technique.'

What comes next in the book is the letters translation for Dovahzul, then a list of Shouts, followed by their English phonetic translation. This is going to be a long ride, but I can get started a Thu'um called Become Ethereal. The word are Feim, Zii, and Gron, Fade, Spirit, and Bind respectively.

If I can at least get Feim, by the end of the year, then I'll be happy.

Another thought comes to mind as I specifically study that one word, 'If I combine this with Swift Release, or even the Byakugan, will that mean I can avoid things that are meant to give my injuries?

"Feim" I test out the word, feeling it out, letting the way it is written in it's natural language flow in my mind. Fade, the first word. It means to gradually grow faint and disappear. I also think about how it connects to Zii, Spirit, and Gron, Bind.

"Feim means Fade, the first Word, Zii is Spirit, the second Word, and Gron is the third Word, Bind, Fade Spirit Bind. Fade to be a spirit, bound for much longer." I think out loud. It does make sense that way.

"Feim," I feel the draw on my magic, but it seems that something is off, something needs more.

"Feim!" I say louder, drawing more energy, but still, not enough, but enough to have me catch my breath.

"Maybe, the Thu'um, Shout, I need to shout it out for it to be more effective!" I hit my head, it was so simple, it even told me in the book!

"FEIM!" I shout, and put a lot of magic into the Thu'um, and then it happens.

Everything turns to a blue hue for a couple of seconds before returning to normal, and I'm left with an ache I'm my throat, that quickly goes away. "That, was awesome." I say, before curling up on the seat and falling asleep.

It was only a couple minutes later when I wake up. "Feim!" I shout out again, and experience the same thing, before it all goes back to normal, only this time, i don't feel the need to curl up and sleep. Instead, it's only a warning ache in my throat.

I take another look in Dovahzul and read just a little bit forget, and come across a small section.

'After using a Thu'um, it is natural to experience a need to rest your voice. this is normal, as our bodies are not made to use the Thu'um like the species that use the Thu'um as their first language.'

Nice to know.

After reading for a few minutes, I try again, that is, after putting the book away. "FEIM!"

Needless to say, I don't stay upright, i fall asleep right then and there, I fall unconscious.

(A couple hours later)

"-I honestly don't know, Madam Pomfrey. All I know is that an unknown spell was used, had a high magical output, and a first year unconscious and unresponsive. I've already explained everything to Professor McGonagall, Professor Snape and Headmaster Dumbledore."

'Who's talking?' I think, and carefully activate the Byakugan to see what's going on, only to be blocked by something completely around me. 'Must be a lot of magic them, cannot get through it, so therefore, to dense for me to see.' I rationalize, before closing it down. I don't need any exhaustive so soon after doing that stunt.

"Well, he should be waking up soon, I'll check up on him and see if he can provide any additional information."

I close my eyes and quickly pretend to be asleep. I don't know where I am, and the Byakugan would be ineffective at gaining information. I need to train on looking through magic instead of looking at it instead.

"I know your awake Mr. Potter. What in Earth were you thinking?

"Would you honestly believe that i was just to excited?"

"Nope, though I can believe that your magic got away with you when you were excited. Though why would there be so much damage to your throat?" The, nurse, doctor(?) asks.

"Ah, maybe I accidentally pushed my magic through my shouting causing the damage?" I hope she buys that lie.

"I can accept that, though I know you are hiding something." She tells me, before waving her wand in a complicated motion over my body, before proclaiming, "Perfectly healthy, now, I guess you can go get Sorted and get on with the feast. If there are any complications, you come to me immediately."

"Yes ma'am." I say, before getting gout of the bed. "Do you know what happened to the things I was with?" I ask.

"Right on the bedside, and your trunk will be sent to your dormitory." She casually responds.

"Thank you ma'am."

(A/N: Sorry for the long delay, I just had to figure out how to write out that scene, and for the Shadow Companion, writing all the minute rules that Lucius Malfoy will use is a pain. Hopefully another story will come out soon in response to a challenge that the creator sent to me specifically. No idea just yet though.)
