The Fire that Warms the Ice (Toshiro Hitsugaya) [Arrancars in the living world]
you had briefly met Captain Hitsugaya by bumping into him on a walk
A knock on your door causes you to look at it and say, "Who's there?"
"Me," you heat Renji's voice at the door.
"What do you want?"
"You are going to be going on a mission to the Living world with me and some others."
"Okay," you say while you start getting prepared for the mission. You open your door and follow Renji to where a small group of Soul Reapers are waiting. You scan the faces and you see Ikkaku, Yumichika, Rangiku, and Captain Hitsugaya.
"Ready," Captain Hitsugaya asked everybody once Renji and you are there.
"Yes," you and everyone say right before you all travel through the Senkaimon to the Living world. Since it is a Cleaner day you all flash step to the Living world. Once in the Living world everyone heads to the Urahara Shop for gigais and soul phones. Then everyone quickly discusses where they will be staying. Renji is going to be staying at Urahara's again. Ikkaku and Yumichika are staying at Keigo's again. Captain Hitsugaya and Rangiku are staying at Orihime's. Rukia, who was already in the Living world, is staying at Ichigo's in his closet as usual. As everyone discuss this they all look at you and decide that you'll be staying at Chad's so he'll have someone to help out over there. After supper at Urahara's everyone takes off to where they will be staying, and Renji helps you get to Chad's place. Once there he knocks on the door and when Chad answers he explains to Chad that I'll be staying over for the duration of the mission then he introduces you two since you have never met, and he takes off once you are in the house and getting situated. After a while Chad goes to bed and you stay up thinking, and while mid-thought your soul phone goes off signaling Arrancars. You sigh using your soul candy and you exit the house out a window and head up to the roof where you're met up with an Arrancar.
You'll have to read the next chapter to find out what happens next when it comes out.
