With the duo having found there way to the tallest building in Shibuya, the girl looked up at the looming challenge. Cracking her knuckles, she said, "I'm off." With that, the girl crouched down before taking off for a running start. Once she got to the base of the building, she continued to attempt to run up it, getting a few steps in before lunging forward, and upward, the building. Reaching out her hands, the girl managed to grip onto the side of the building, pressing her fingers in and making a grip if there was none. From there, with surprisingly agility and rhythm, she began to throw her other arm up and dig grab onto the building with that, hoisting herself up before continually going back and forth with her arms for this. It took awhile and she definitely seemed to be exerting herself, but Aeira did not slow down in her entire ascent of the building. Once she got to the top, she was greeted with the sight of a flag, and after huffing a bit to catch her breath, grabbed it. After catching her breath, the girl looked down only to sigh at the realization that she had now had to get down the building. With flag in hand, the girl dug her hand into the side of the building before letting herself dangle. Once she was doing such, the girl let go of the building, beginning to fall, only to grip back onto the side of the building as she started to speed up. Her hand slid down the building's side as she continued to try to dig her fingers back into the wall, once doing so stopping her descent entirely. She continued to repeat the process until she finally fell back to the ground. Once there, she shook her arm out, only to let it hang at her side to rest it. Huffing for air heavily, the girl raised the flag as she looked towards Vallus. "Done." With their task done, Aeira began to walk back to where Charlie was to show that they had completed the task.
