After leaving Katerina's mansion, Elena and Tomoe started to follow Nave toward the gates of the fourth area. Actually now that all the negotiations for the house were done, Nave should have returned back to her office. But she was planning to take this opportunity to spend some more time away from her job. But she was not planning to slack off and instead wanted to help Elena and Tomoe out a little bit.
Nave had always found Elena and Tomoe to be super cool but after seeing how insanely powerful Elena was, she had become a fangirl. In her whole life, Nave had never seen her friend Katerina struggling in a fight. Even though there were fights that she lost, she had never been helpless in those fights. This was the first time when Nave had seen her friend getting dominated this way.
