"You can keep your promise and protect this world just the same," Rukia frowned, folding her arms. "I, too, was concerned about the ramifications of abandoning my duties as a shinigami. However, I learned that my concerns were unjustified when someone else from my world appeared in the city."

She sat back on her heels, head bowed. "He seems to have been taken here from an earlier point in time than I was. And yet, even so, there was no evidence that he had ever gone missing. I think it is safe to say that we will be returned to our worlds once we have succeeded in our mission here. What's more..."

The shinigami huffed a little sigh, then smiled. "You won't have to fight your world's evil alone. If we are able to travel from here to our home world, then it's possible we might travel to each other's worlds as well. I would gladly lend you my aid, if you wish it."
