Yu Park

 Yu Park (박유) is the hand-to-hand combat specialist and strength of Nereids.

Biography
Yu Park was a convicted felon who was captured by Rena Honjo of Nereids. However, Rena offered her a job as part of the crew and Yu then began to develop a respect for her. She is taciturn, ridiculously strong, and good with hand-to-hand combat, although she is fond of animals. Yu does not get along with Gloria and constantly hits her. Despite that, they make a good team as Yu's fighting skills go well with Gloria's shooting. Yu's fighting style is similar to taekwondo.

Trivia

 * It is implied that she is Korean.
 * Her fighting style is implied to be Taekwondo, Hapkido or Taekkyeon (since both styles involve kicks, mainly spinning kicks).
 * She is the tallest of all Nereids members.
