Agent 09, Kim Taeyeon : 

An excellent leader that can lead the girls anywhere, and of course, the girls will follow. Secretly, she is in a relationship with Leeteuk, but proceeds to keep it secret despite the fact that everyone already knows. While she may not be physically capable for the demandig missions they are told to conquer, she more than makes up for it with her talent with words and strategies.

.

Agent 22, Jung Jessica : 

The ice princess that is skilled in many different areas. She is an assassin, and a talented sniper, leading many to think she's perhaps a ninja. They could be correct. She is in a relationship with Donghae, and constantly reminds everyone by annoying them with their closeness. No one can forget that. She has a sister she would do anything for, perhaps one of her only weaknesses.

Agent 12, Lee Sunny :

Our main character who is new to the game of these hitmen. She was selected by Kyuhyun to join the Academy, and has not yet regretted it, not even once. She is an all-around player, good at hacking, shooting, hand-to-hand fighting, handy with a toolbox, and doesn't ever hold back anything. She constantly has tricks up her sleeve, and surprises everyone with what she can do. 

.

Agent 00, Hwang Tiffany : 

The loud and sweet pink princess that can be as deceiving as the devil. She can speak most languages fluently, or at least without a noticeable accent, and can learn the basics of any language in days. And if all else fails, there's always her beautiful eye smile to help her. She is belittled by Heechul constantly, but finds herself drawn to his irresistible charm. One of the best undercover agents of her generation.

Agent 32, Kim Hyoyeon :

Strong and powerful, in times of need, this person won't let you down. While she may be a little weak mentally, physically, she's not somone to mess with. Well, in general, you shouldn't mess with her. Almost like a volcano, when she blows, she erupts. And takes down everyone close to her in an effort to get back up. Thank God Eunhyuk will always be there for her.

Agent 21, Kwon Yuri :

ier than hell, with a body of pure muscle, we have. . . the therapist. But admittedly, she's an expert at solving other's problems. Maybe it's because she had so many of her own. When her parents abandoned her and her two sisters, Yoona and Seohyun, she took care of them. She turned out well anyways. Cute, innocent and powerful, along with Tiffany, she can be an incredible undercover agent.

Agent 24, Choi Sooyoung : 

The tall, beautiful food goddess. Quite literally, actually. Her job for the team is to be the big baby, whining about not getting enough food for her stick thin body. Even though she eats more than five of the girls combined. Her food mania, however, has an upside. She is so obsessed about food, that she knows everything about it, which makes for a very skilled poison detector. Whether they like it or not, she takes a bite of every team member's food, ever day, evey meal. You know, in case of "poison." She is in a relationship with Ryeowook with the foundation being food. Obviously.

Agent 07, Im Yoona : 

The pretty sister of Seohyun and Yuri with trust issues. Once you've got her trust, you better not break it. In doing so, you would irrevocably break her essence. Gifted with the gift of iron abs, beauty, and a talent for medical problems. Like her older sister, Yuri, she had to be brave for everyone else many times. She has an interest in art and taking pictures. She also has an interest in Choi Siwon, but has apparently decided he is not good for her. She doesn't really believe that, though.

Agent 11, Seo Ju Hyun, Seohyun : 

An upright and proper young lady who was basically brought up by two girls practically her age. Innocent and charming, she is the analyst of the team, making observations no one would have thought of. Extremely intelligent, her boyfriend is Yonghwa. This makes things difficult because he, unfortunately, is not a Wilted Rose. He is normal. The only thing Seohyun ever wanted to be.

Cho Kyuhyun :

Sunny's best friend, who helped her through everything. A computer genius, he taught Sunny everything he knows, and considers her his little prodigy. A while back, he dated Seohyun, but after meeting her sisters, he realized they were too scary and had to break up with her. Everyone were both okay with it and no grudges were harbored. 

I saw this, and it's so cute, i wanted to share it with you.
