Grimmjow: I'll slit your throat

Grimmjow dashed towards Y/n with a slash but Y/n used flashstepped out of the way.Y/n unleashed his Bankai then dashed towards Grimmjow who charged at him with a slash.

Y/n charged up a cero of his own and fired it at Grimmjow who just grinned. She fired  point shaped bombs destroying the blade and flying at Y/n. Y/n saw them  coming at him then rapidly slashed them away.

Y/n: Nice try but i'm not it's gonna take alot more than that to take me down!

Grimmjow: HAHAHAHAHA THAT'S WHAT I LIKE TO HEAR COME ON!!! A FIGHT LIKE THIS IS WHAT I'VE BEEN WAITING FOR TIME TO GO ALL OUT!!

Grimmjow ran towards him then kicked him. Y/n blocked the strike but was pushed back by the force. Grimmjow charged towards him then jumped into the air and fired a Gran Rey Cero then her spirit energy appeared from the claws and formed into  giant blue claw. Grinning Grimmjow  slashed towards him sending the energy at him.

Grimmjow: Desgarron!

As the massive blast went off  the force from the blast caused the people of Kouh to look in shock and horror at the explosion in the sky. At the school the devils looked in shock  at what was happening.

Rias:(Mind) This power is insane! I have no idea just who's it is but I just hope that they are not our enemies.

Kiba:(Mind) I don't know who your fighting Y/n but their strength is scary.

Koneko/Akeno:(Mind)..... Y/n

Asia: (Mind) You can win this Y/n. I know you can.

When the blast cleared Y/n stood unharmed. Grimmjow looked him with shock when she noticed he was wearing a mask.

Grimmjow:(Mind) That mask it's just like when I was fighting Ichigo.  Just who the hell is he and what the hell is this weird feeling in my chest?

Y/n: What's wrong Grimmjow you seem surprise. Did you think I would be killed by that? Well sorry to tell you but there is no way in hell i'm gonna lose to you. So bring it on!

Grimmjow looked at him in with slight blush for a second them grinned and charged at him.

Grimmjow: LET'S DO THIS L/N!!!!!!

Y/n charged at Grimmjow but before the two's attack could land a garganta appeared infront of them. The two stopped then looked as someone came out it. It was a woman with white skin. She had long black hair with fragment of a mask in it. Her eyes were green and under them were lines going down her face that matched.

Grimmjow: What the hell are you doing here Ulquiorra get out of my way!

Ulquiorra: Harribel has sent me to retrieve you and bring you back to las Noches.

Grimmjow: I don't care i'm in the middle of something!

Ulquiorra turned to Y/n and stood with a small bit of surprise at his strength.

Ulquiorra;(Mind) his strength is like that of Ichigo Kurosaki....no it's different it's much stronger. (to Grimmjow) If you were to continue fighting him you would die now come along.

Ulquiorra grabbed Grimmjow's shoulder but Grimmjow knocked it off then scoffed.

Grimmjow: Fine we'll continue this another time L/n.

She said walking through the garganta and the two vanished.

Y/n: I should head back to the school and see what Kistuke's letter says for now. I will have to  tell the others.

Timeskip brought to you by Chibi Grimmjow and Koneko fighting over a ball of Yarn while Y/n records it

Y/n pov

After school I headed to the Soul Society and went to Kukaku's place. When I made it I was greeted by a familiar face who just grinned.

Ganju : Well looks like your here what I'll show you where we're keeping her.

He he showed me to a room and I opened it  and spoke.

Y/n:Looks like your awake 

Raynare.
