Senna (Mangetsu20)/Reigai

Senna (茜雫, Senna) or sometimes referred as Senna Fukuseihin, to distinguish herself from her visibly twin "sister" Senna Inaba, despite the notable height difference and chosen choice of clothes or hair ribbon color. She is the product of Captain Inaba's Reigai research, making her a enhanced and thoroughly trained duplicate of his "daughter" to serve as both a companion to her as well as a sparring partner.
