Nono, Castle Tepes
Nono waited patiently as Shirley stumbled about for an answer, knowing that feeling fairly well, and not in a hurry to push the servant. It was the least she could do, since she obviously seemed uncomfortable answering, which Nono was used to in her time working before she met the Fraternity.
That abruptly vanished as Geo fell into, and then through, the girl, earning wide eyes from the gynoid. Well then, that was coo, though the cry was less so. "Geo, that was mean," she said, fairly rounding on the boy in time with the Queen. Honestly, he should know better, even as he apologized fervently.
"Come on, let's go," she said with a grin as she returned to the maid, doing the best she could to pat her on the shoulder before following Saber inside the Castle.
Before they could entirely make it though, two portals appeared, reinforcements, as they introduced themselves. "Hey Jack, Kazuma," she said with a wave as she moved, certainly glad to see the help. They were strong, so now Shadow Eternity would have an even harder time getting the relic here. But she didn't let that stop her, as she moved after the Queen.
Misaka 10,032, Academy City
Misaka was pleased to see Marisa choose the easy option, and in turn returned her weapon to the bag on her back before moving to follow after, leaving the lab and exiting into the hillside of District 21. She knew the reasons that they had been placed out here, and did not object to them in the total of cost benefit analysis. That still did not make it any less annoying for transportation though.
She kept to the rear, a careful eye kept on the Witch that had stolen her goggles and forced them to chase her before. She would not allow a repeat occurrence, especially in Academy City. Who knew what Marisa could get up to while she was in here, with it's collection of advanced technology and powered people?
She glanced forward at the question, quickly coming up with an answer. "'Walking would be the better idea. Moving above ground allows for easier assistance from police services, as well as other authorities,' Misaka says with some regret at her tired legs," Misaka said even as she noted the dilemma they faced. But better to take a route that would allow a rapid response from the Sisters or Antiskill and was heavily monitored, rather than the subways.
Still, she acknowledged the problem and prepared herself accordingly. If the thief wanted to try something on the way to the Windowless Building, she would have to be prepared to get past Misaka to do so.
