Rukia was completely clueless about the modern World and Technologies in it. Although luckily for her before you joined the Soul Society as a soul reaper. You lived in the human world for your whole life and knew all of the Technologies around it.

Today was a rather a dull day for the soul Society with no new Missions to go on. So you decided that it might as well be today that you show her some of the modern World. When you went up and asked her she immediately agreed since she was so curious.

After opening a Senkaimon gate you'd bring her to the human world, and what better place would that be? The capital of Japan, Tokyo. Once she stepped out of the gate she'd look around in awe at all of the buildings.

She turned her head and looked up at you in amazement before speaking in a more lower tone although she was obviously excited.

"Wow... So this is the modern World?"
