The Shakedown..

Koga stops and looks back.
"Oh yes I knew I forgot something."
Koga draws his zanpaktou and looks at the hollow.
"Your still able to talk and a male. Your screams of pain and agony aren't so thrilling to me. All actuality they are quite annoying. So I will destroy your vocal box."
Koga smile is deep.
"Put him down Rizu. I need to carve his voice box out of his body before he annoys me farther."

*Staring blankly at Koga, Rizu hesitates as she slowly brings Kuroi over to the table and lays him back.* Captain...forgive me, but...is that truly necessary? Could you not just sedate him? Or...something?

-He looks at the male shinigami-Great.Just great.You are really a crazy man.-He lays back on the table staring up at the lights-Lets just get this over with and stop dragging this on any further.-He closes his eyes as he waits there-

"Sedation? Then how would I know if its affecting him properly?"
Koga picks his zanpaktou up into the air,the blade facing the hollow's vocal box.
"And don't worry I'll fill it with seki seki rock fragments just so u wont be able to regenerate."
Koga says with a smile as he plunges his blade down toward's the hollow's vocal box.

*Rizu uses Hagane and grabs Koga's blade before it reaches Kuroi's throat, immediately bowing her head.* I'm sorry, I insist that we analyze this further. At the very least don't prevent him from regenerating. Whether you sedate him or not, his reaction to the poisons will not necessarily be what you want them to be. He is no arrancar. He still has his mask.

-He does not open his eyes but remains silent thinking to himself-This guy is really bent on experimenting on hollows.I am glad Rizu stepped in or my neck would have been split in two.Well at least i can still talk for now.-He says all this to himself in his head-

Koga glares at Rizu with a deathly look.
"Then get out of my lab."
Koga focuses his spirit energy into his right leg and horizontally kicks at Rizu.
"Get out of my lab if you don't have the stomach for this."
Koga's voice is as cold as the north pole as he slashes at the voice box again.

*Rizu attempts to dodge the kick as it hits her in the left side, still throwing her back into a wall.* Nngh! *She scrambles to her feet and rushes over to Koga.* Wait! *She bows deeply this time, holding her hand to her left side.* I insist we sedate him. If it doesn't work as you like, I will bring you back an arrancar. Or die in the process.

-He still has his eyes closed thinking to himself-Great now the crazy man wants to fight.This guy has some serious mental issues.I thought hollows were bad but this guy is worse.-He lays there still talking to himself inside his head-

"I have more than enough current Arrancars."
Koga lifts his index finger from the grip.
"Sai."
The finger pointed towards Rizu.
"Now to finish this so I can begin."
Koga plunges the blade in towards the vocal box.
"Do I get to feast on him Koga!?!?!?"
Koga hears the voice but pushes it aside.

*Rizu focuses her reiatsu to break through the sai and reaches both hands out to grab Koga's blade, wincing as it cuts the palms of her hands.* Tch...Koga taicho. There is something very, very different about this hollow. He needs to be operated on carefully! You need to approach this carefully. *She looks up at Koga, noticing that the strange threads within his aura are spiking.* -Something is unstable and it becomes more prominent with violence. There is something very, very wrong...-

-He still does not open his eyes-This place reeks of hollow blood.He must have been trying to merge with it.I could speak out and say something.But i rather not get involved in their little fiesta.-He still talking to himself in his thoughts-

Koga's spirit energy increases to about three times as much as Rizu's max.
"Get out of my lab. I know exactly what im doing."
Koga's voice is as cold as ice when he speaks.
Koga blasts a hado 31 out of his mouth at Rizu and looks back at the squad members behind him.
"Get her out of here. Now."
Koga has no anger in his voice when he talks,just sheer ice.
Koga slashes again at the hollow's vocal box.
Koga although had an apifany and stops a milometer short.
"Make you a deal hollow. Tell me EVERYTHING I want to know without leaving anything out and I will give you bare minimal experimentation and let you go even if your lucky."

*Rizu uses Bakudo #39 Enkosen to brace the impact of the hado and falls backwards, hitting her head against the wall.* Ugh... *As the squad members attempt to take her, she shakes them off and runs back to Koga's side, bowing deeply.* I'm not leaving. I...I won't interrupt any further. I just...had some concerns...that don't matter. *Thinking to herself, she hesitates before speaking.* -Concerns that matter...pick your battles, Rizu. You can analyze his aura later. Don't get yourself killed.- P-please forgive me.

-He opens his eyes-So you want to know everything.I know very little but i do know this.The ones the hollows call Aizen is planning something.I did not stick around long enough to hear all of it but it has something to do with that town.You can trying planning for this but he is already a step ahead.-he closes his eyes again after speaking knowing what he said is the truth-

Koga looks at Rizu.
"Then stop gettnig in my way will ya."
Koga says with a smile.
Koga then looks at the hollow.
"So Aizen is planning something after all. Guess we'll just have to step it up and destroy him."

Over the course of 2 hours Koga completes his experiments on the hollows.
One of the experiments included installing data gathering bacteria into the hollow so everything he see's and learns from that point on can be observed.
Koga releases the hollow secretly through a personal senkimon he has been working on slowly for his own home.

*After the hollow is released, Rizu sighs, relieved that the experiment went off without any mishaps. She turns her attention back to Koga, carefully choosing her words.* Captain, i-if I may...could I run a concern of mine by you? Please.

-He is knocked out on the ground laying in a strange place still dazed-Where am i?That is the last time i fight a shinigami.-He thinks all this to himself in his dazed state trying to make heads and tails of things that happened-

Koga looks at Rizu curiously.
"Sure I guess. I am your Captain after all."
Koga says with a slight chuckle.
He puts his left hand on the top of his zanpaktou's hilt.

*Rizu nods and looks up at Koga, frowning slightly as she analyzes his aura.* Well, the reason for my insubordination...I noticed something. About you. There is something very different about your aura, something I can't really distinguish. It wasn't there before and it would spike whenever you would get close to decimating that hollow. I can't explain it better than, well...bloodlust. If I'm overstepping my bounds by inquiring, I apologize. I just want to understand it.

"hhmm a diffrence in Aura?"
Koga asks questionably,acting slightly confused.
"So that thing does give off an aura."
Koga thinks to himselfs.
"Maybe it's my bankai still having some late affects on you. You said you sensed a different Aura during our spar didn't you?"

*Studying Koga as he speaks, she raises an eyebrow quizzically.* Well, yes...I did say that...but it's more evident now and much easier to see clearly. Before, when we were sparring, it was risidual almost. A blur, I could hardly tell. Now it's all through your body. *Taking a step forward, she points her index finger towards the center of his torso.* Emanating from the center. *Shaking her head, she frowns again.* I am not mistaken Koga. I'm confident that there is something else in your aura. Sharing it.

Koga gives off a slight chuckle.
"Two souls can not live inside one being Rizu."
Koga says with a smile as he begins to walk.
"One will over power the other or their vessel will die.And last I checked only me and my zanpaktou lived in union. Even he lives inside a zanpaktou and not my body."

*Rizu jogs a little to catch up to Koga and keeps her eyes on him as he walks.* I know this, which is why it's so strange. Captain, I swear to you I am not mistaken. Your aura has been altered. I've never seen anything like it. I would stake my very life on this.

Koga looks over his shoulder and smiles.
"Don't worry Rizu. For all we know its the affect of my bankai on you. It could also be when I was experimenting some drugs on myself earlier today."
Koga continues to walk,his left hand laying gently on his zanpaktou's hilt.
"Don't worry if anything ill destroy the essence within me."
