Hana Somei/Plot

History
In the past, Somei was forced by her father to study continuously in order to maintain high marks, though Somei did it principally for the benefit of self-awareness. During the First Large-Scale Invasion, she saved her neighbor Katori from the rubble when their neighborhood was destroyed by Trion Warriors. She was later hospitalized due to several minor injuries. When Katori asked about her decision, she explains that the reason she saved her instead of her family was because she had the higher chance of being saved. After the invasion, she stayed at her cousin's house for a while before planning on joining Border and become the very best.
