It seems everyone here knows more than he does. Rokuro who has yet to meet someone who is struggling on the same level with the most simple of modern amenities. After he figures out how toilets, showers, and microwaves work, maybe he'll have enough spare time and energy to learn basic mechanics.

"As you wish." Rokuro creates further space between himself and his chosen targets, heel digging into the dirt as he finds a more grounded posture. He sends a surge of water in their direction with his left hand, soaking their weapons and knocking them back, and with his right he draws a shimmering protective 'bubble' around Kylo, which will absorb the brunt of most attacks.

Thankfully, the concept of multi-tasking has existed since the dawn of time, and so Rokuro is at least on par with his comrades in that regard, if not a little further ahead-- everything he knows how to do, he can do without technology.
