Ran is this generation's Prophet in Gabe and, therefore, she has the ability to see into the future. She goes every now and then into Lux to sell flowers, but recently she seems to just follow people around. She takes special interest in Ichise and helps him escape from the sewers when Isshii's men throw him down there.

Spoiler

She acts as a kind of restraint for Ichise while he learned how to use his Texhnolyze better.
