With that they got to the training, she picked it up quickly and after a practicing it herself, he saw already lines of stress easing throughout her body, when it was done, they spent a few more hours just relaxing before he excused himself "It's good to see you again, but I have to be off and away." He told her with a smile "I still have many duties to attend to and the paperwork won't do itself, Ukitake-sama is relying on me...and earlier, it wasn't that Abarai-san might pick on you, I was just warning him to make sure you do alright."
Then he got up and bid her farewell. From there a week or so passed, with them visiting on occasion but not really having time to do more, it was then that a problem arose for the lieutenant, who after getting some advise from his Captain, came to Hana "I have a...delicate matter I need you to take care of, my Captain advised me to only come to someone I trust, he'd normally send me, but my workload is too big for me to do this, I need you to go to Earth and find Kuchiki Rukia, one of my squadmates, we haven't heard any word from her in over a week and I'm getting a bit worried, can you go and find out if she's still alive, and if so if she's alright?"
He hoped Hana would be receptive "I've already cleared it with Abarai-san, who has agreed to uh...keep this little venture of yours a secret from your Captain, I don't want him to know just yet, if there's a problem we'll let him know but I see no purpose in bringing something to his attention that may be totally trivial and not a problem at all." Arashi looked at her "Can I count on you for this?"
