Serena Rinnen

Serena Rinnen is a Regular. She passed most of the tests on the second floor and was assigned the Scout position. She was a thief before she came to the inner Tower.

History
Rinnen used to be a thief, who raided various trader caravans for wealth. However, one day she ran into a caravan protected by a Ranker, and her whole group was decimated. After she realized that fragility of human life, she was then approached by Headon, who enrolled her as a regular and teleported her to the inner Tower.

Plot Summary
Serena managed to pass the first test on the Second Floor, by attacking and disembering everyone she ran into. She teamed up with Phonsekal Laure and Ho and participated in the Crown Game with them. She barely got through Leo-Ro's Shinsoo barrier. She was then assigned to be a Scout.

For the hide-and-seek test, she was put on Team B. She positioned herself with Ho according to Androssi's plan. She talked to Ho about how she had initially felt great about beating the other Regulars in the first test, but as she got to know those who made it through, she imagined having to kill them to ascend The tower, and was disgusted at the thought. She then yelled at Ho, who mysteriously ran off.
