Gina Higanbana
彼岸花 ジーナ

Speaking of eccentric mad scientists! Gina Higanbana, the  Former Ultimate Biochemist is the sort of person who definitely befriended every monster under her bed when she was young. Gina is a boisterous workaholic which has paid off since she is known most for her study of parabiosis. Unfortunately, not all of her fame is from positive feedback as some of her testing methods have been found very unorthodox…
Gina presents herself as larger than life, after all, she is a woman of science! Though she delves with modern problems, her way of talking is very old fashioned and even poetic, making her sound like she would fit right into a 19th-century romance novel.  
While she definitely has a presence in the group, Gina tends to withdraw to her own space. Not making friends in a killing game is probably a good call.
