Ok, Sachiel Angelo since you were the first to answer.
Here it is.
"Ugh!"
Ichigo dug his fingers into the back of Yoshios Shihakusho.
"Utsu, Kagede Ansatsu *."
His intestines began to burn like they were set on fire.
He cursed.
"Why?"
"I still can't stand it, that he has you, instead of me. So I'll force him to leave you."
"Are you saying you'll kill me so we will be separated?"
Yoshio pulled his Aikuchi type Tantō out of Ichigo.
He had aimed for the hazel-eyed torso, right below the ribs.
"I'm sad that you think like that Taicho. And I wonder. How come you never where interested in my sword and it's abilities?"
After a moment of pause Yoshio continued, while watching Ichigo bending over and covering the stabbing wound with a hand.
"Anyway I'll tell you now. As you can see my sword is a short blade. The reason you never saw it is, that I wear it bound on my left lower arm. Well covered by my uniforms sleeve. So when I release Kagede Ansatsus Shikai form, the blade turns black and a poison will be set free. That poison is in your system now and it will not leave as long as I refuse it. It's highly effective on Hollows, so maybe you think why using it on you than?"
Ichigo had sunken to his knees, panting.
"Right. So why?"
"The poison reacts to the reiatsu of a Hollow, the greater it is, the more effective it will get. It feeds from the reiatsu. Not to mention that it throws the regenerative abilities of Hollows off. It's a real cruel death, don't you think?"
"So...what's...the point?"
"Can't you tell? Well maybe I let you fell it than. Dokusatsu.* ² "
Ichigos eyes ribbed wide open and he yelled in pain.
His right side was on fire again, but worse than before.
"Do you understand now? When your lovely Hollows reiatsu will be around you, it will kill you. It's not much that's in this necklace, but the direct contact with your body gives you a slight taste of the pain, Fuku-taicho will cause you."
"Shit!"
Ichigo shifted, so he could hold himself up only on his knees, the bleeding got worse.
His free hand moved up to the necklace, while he glared at Yoshio who held his blade with Ichigos blood dripping from its tip.
"What did you say?"
Hichigo almost yelled.
"I knew I shouldn't try and trust him. Why didn't I check for this?"
He froze.
Yuzu looked worried at his horrified expression.
"Shiro...nii?"
"Shit!"
He stormed out leaving a confused Yuzu behind.
'Ichigo! Ichigos reiatsu fell quickly just now. Shit! Wait! Hold on until I come to save you!'
Ichigo ripped the necklace off and threw it away.
"Oh? That was unexpected. I thought you'd cling to it until you bled your body out."
"I...won't...let you have...your way so easily..."
Ichigo collapsed.
"Mhh? Done already?"
Yoshio asked more to himself and crooked an eyebrow, noticing that his Captain was sill conscious.
Ichigo tensed up and whined.
"Ichigo! Hang on!"
Hichigo ran over to his lover and tried to help him sit up.
When he touched Ichigo the mans whimpers turned into a loud pained cry.
"Don't touch me!"
Hichigo drew his hands back and clenched them into fists.
He glared at Yoshio, who watched the scene with a grin.
"You!"
"Aww, Fuku-taicho, you shouldn't let your reiatsu burst out like that if you're really worried about Taicho."
"Damned brat!"
Hichigo snapped.
He attacked Yoshio with bare hands, got him by his throat and heaved him off his feet.
He grinned in an insane way at the helpless Shinigami.
"I know about your Zanpakuto, thanks to Yuzus research. I assume you poisoned him. Bad for you, 'cause you gave me a reason to kill you. When I won't be able to stay beside Ichigo anymore, I don't need to hold back anymore!"
Hichigo raised his reiatsu to it's barriers and forced it to go above them
The seals markings started to glow and burned away, leaving cuts in their place, while his hair grew long again.
Hichigo didn't even twitch when the seal cut into his flesh.
"Have you lost it...so far already,...that you don't care about him...anymore?"
Yoshio rattled.
Hichigos smirk grew so wide, you might think it would cut his face in half as he whispered into Yoshios ear
"You're wrong. Look at him, he's unconscious right now, but nothing more. To bad for you that I let the bureau develop a device to block my reiatsu long ago. But, you're gonna die."
With that he ripped Yoshios throat and dropped the dead body.
He went over to Ichigo, sadness washing over his body.
"I'll keep my promise, aisuru."
Picking his denrei shiki (the phone Shinigami use) he called for aid from the medic team.
"My Captain is injured. We're on the hills in western Rukongai, around district 250. Yeah I'll do what I can to stabilize him until you arrive. Bring a second stretcher. You'll need it for a dead comrade."
He ended the call and looked at Ichigo once more.
Than he opened a Garganta Gate.
"Forgive me, Ichigo."
He left through it and on the other side he faced Grimmjow.
"I've come to take your throne."
The ex-Espada grinned back at him.
"About damned time."
