Unohana stood up and discretely rubbed Ryoma's abdomen, the place where the deadliest wound had been.
"You are currently in the headquarters of the 4th Division, this is an underground abandoned facility. After your fight with Zaraki Kenpachi, you were heavily injured and experienced deep trauma then collapsed due to Reiryoku depletion. I brought back the two of you here for a recovery process. After treating Captain Zaraki with Kaidō, he has yet to heal after two days".
"..."
"I haven't done any treatment to you, and you are already healed completely... as if you hadn't fought at all, not even a scar left from wounds that were life-threatening to anyone else".
"..."
Unohana closed up, her lips gracing his ears but rather than a seductive aura, there was this eerie darkness enveloping her that sent chills to Ryōma.
"Would like to explain that, Ryōma-kun?~"
"..."
Hearing no answer, Unohana regained her spot and took something out of her robes. It was a small stack of papers and scrolls.
"As interested as I am, I have done a bit of personal research on you, I hope you don't mind~"
"Not at all..."
"As you should~ the thirteenth division under Captain Ukitake is the one tasked to send Shinigami to earth to reap souls in the world of the living. We keep a tight register of all the souls who are reaped and sent into the Rukongai and although those records are rarely touched, they exist and are available for all Shinigami above Lieutenant rank for exceptional cases such as this"
Her hand rose and in it, there was a bright aura, "If you may excuse me again, I took a sample of your Reiryoku for this process, you don't mind, right?~".
"Not at all..."
"As you should~".
"..." Ryōma's brows twitched at her weariness. The question was polite, but her intentions were not, he felt his life was in danger every time she asked a question, and rarely anyone could achieve that.
Aside from making her prettier, that loose long black hair was making her scarier. He couldn't help but look towards her pronounced cleavage where she had a deep scar in the middle of her big chest. After a brief look, he settled on her eyes once more, but Unohana had already noticed her gaze and was smiling at him.
She coughed slightly and dismissed his gaze.
"The result is that I couldn't find you in this register... which means your soul was not reaped on earth and brought to Rokungai. You are a Ryōka (invader) Kamishiro-kun, could you explain that to me?".
"For real?" He asked, surprised.
"For real~"
"I see..."
He didn't answer once more, this time he truly didn't have an answer to that question and was puzzled as to why this was the case.
'Shitsutora mentioned the same...'
She then took something else from outside her robes, they were two swords: Shitsutora and Hebimaru. She put Hebimaru on his lap gently and then took Shitsutora and inspected it.
"This Zampakutō is not simple... others might not know, but I'm old enough to know a thing or two about it. I know it is prideful and wouldn't bond to just anyone, but for you to be able to achieve Shikai with it, is not surprising given your talent... what's surprising is that you can achieve Shikai with another sword and also... that prideful white tiger is willing to share your Reiatsu with another sword. The reasons for your Reiryoku depletion were two".
She raised one finger.
"First, Zaraki Kenpachi's capability to gather Reiryoku towards himself".
Then a second finger.
"Second, your overconsumption due to your devastating double release. So? How care you capable of this?".
"I am that special, Retsu~" Ryoma smirked, sitting opposite to her on the table and even gaining a comfortable position.
"Fufu~"
*WHOOSH!*
As fast as lightning she unsheated Shitsutora and pointed it at Ryoma's neck, cutting a bit of it until blood dripped.
"An interesting talk, but shall we stop the games, Ryōma? Who are you...? What are you? As a Captain of the Gotei13, it is my responsibility to keep the Seireitei safe against foreign threats. Right now you are a Ryōka, I can categorise you as such... your true nature is unknown but if you're not a soul and you are not human, you can only be hollow..."
"Kill me then" He took the edge of that sword and pointed it further against his neck.
"..."
"But know this; I won't go down without a good fight~".
Unohana sighed, removed the sword and passed it to him.
"You are reckless with no sense of self-preservation. The only reason you are not currently being assailed, executed... exterminated... experimented on... is that I am keeping you secluded here. Do you not understand that?".
"Never asked you to–"
*CLAANG!!*
*BOOOMMMM!!*
Ryōma felt a literal truck strike him. He parried the strike on time but was still blown towards the walls of the room like a rocket. He impacted the walls and noticed they didn't shatter or crumble, instead, a barrier had been laid out around the edges.
"Your stubbornness is irritating," said the woman, now wielding her Zampakutō.
Ryōma stood up with his hands shaking at the shock of that previous strike. He could gauge her strength was even superior to Kenpachi, which didn't make sense. He noticed he was wearing nothing but a mantle around his crotch which eventually fell, making things a bit awkward, but Unohana was unfaced, she just looked at him awaiting his response.
"You have been talking a lot of nonsense for a while. I don't care about your questions, be real. Either you fight me or you let me go, which one will it be, Retsu?"
Unohana tilted her head and sighed in disappointment.
"This is why the younger generation is so impertinent nowadays... there are too many compassionate elders like me. A bit of a stronger hand is needed to discipline your perverted kind".
She pointed her sword forward.
"This is what is going to happen, Ryōma-kun. You will join the 4th division alongside me, do you accept?".
"How about no!~" He prepared to Shunpo with Hebimaru.
*WHOOSH!*
!!!
The next thing he saw was his torso falling, Hebimaru split in two... torrents of blood.
Utter defeat and even death.
"I never asked you, Ryōma. You will have to accept"
Unohana's hair waved; she turned around, looking at him with that cold glare and a slight smile then looked to the left side of her coat where she had been cut and blood dripped.
Even if just slightly, Ryōma had managed to parry that strike.
She imbued her hand in green kidō, Kaidō, and healed up that wound as she walked towards Ryōma who groaned in pain and looked at her in anger. To the naked eye, the blood was flowing back into place as his torso and bottom attracted to each other like magnets.
"What a glorious sight to behold. If you stayed here... wouldn't that give my life and yours a lot of sense? You wish to fight someone strong, don't you? Then stay here... back then you told me you wished to defeat Kenpachi, then now is your chance"
*RUMBLE!*
Catastrophic Reiatsu filled the world, it was incomparable to anything he had ever felt with the last Zaraki approaching just slightly, it sent Ryoma's body even further into the ground as his blood boiled at the mere sight of her.
The kind of woman he had always been looking for.
"I am Yachiru Unohana, The First Kenpachi".
