Saika and Rin Kagamine - 鏡音さいかと凛

Name: Saika Kagamine - 鏡音さいか
Gender: Female
Age: 15
Birthday: May 21st
Sexuality: Bisexual
Special Characteristics: Her eyes turn red when she uses her magic. She's also near-sighted and has to wear glasses.

Personality: When you first meet Saika, you'll see a quiet, nerdy girl with a maternal streak. She's very polite and proper, what you might see when you think of a perfect young lady. In conversations, she doesn't talk too much, being of the dandere type. However, to those she comes to know, you start to see how motherly a figure she is. Always one to correct you on your posture, and someone who does well with younger children, Saika is a perfect Onee-chan character as well. She's extremely protective of those she has grown to love, someone you'd expect to say, "No! That's too dangerous!" or "It'll be alright, I'll get you a Band-Aid."

The main subject of her motherliness, however, is directed right at Rin. Being the older of the sisters, Saika feels it's her responsibility to make sure absolutely nothing bad happens to her little sis. She's overly protective, refusing to allow Rin to do even the least dangerous of things. She can also be often seen scolding the aloof girl, correcting her on her manners and making sure she's presentable. Saika would do absolutely anything for Rin, so devoted she is to her. In fact, she's so devoted to her, it brings out another aspect of her personality that isn't quite so loving and gentle as the other ones are.

Saika loves her sister so much to the point where things get creepy. She might follow her around, stalking her even when she's just going to get something down the street. She tastes Rin's food before she eats it, and refuses to allow the younger girl to go anywhere until she has ensured things are safe. She grows incredibly jealous of anyone who even goes near her, almost isolating Rin. In the past, people who spent too much time around Rin would suddenly disappear, only to be found brutally murdered a few days later. All of this was the possessive older sister, Saika's doing. 

She can become sadistic in battle, loving to see her enemies grovel before her. Every enemy she fights is a potential threat to her darling Rin, and so she wishes to make them pay as much as possible, wants to see these potential enemies pay for things they may have never done. Her fighting style is chaotic, wild, and unpredictable, making her a dangerous opponent despite her weaker strength. Her true nature shows itself completely with the wild light in her eyes and the shocking brutality with which she attacks. She is completely driven by her love for Rin, doing everything she thinks that will be good for Rin.

Under a leader, Saika is usually a rather obedient, submissive follower, she'll do as asked, performing tasks with precision and focus. However, if any of this gets in the way of her to her sister, she'll immediately switch back to her sadistic personality, going through anyone to get to. Rin, no matter if it is enemy or ally. As a leader, she is equally chaotic, being a quiet, democratic leader unless Rin is badly affected. 

To sum Saika up, her life revolves around Rin. Every action she does is to keep her safe, whether Rin likes it or not. And she'll do anything to achieve this.

Name: Rin Kagamine - 鏡音凛
Gender: Female
Age: 14
Birthday: November 3rd
Sexuality: Asexual, but if she had to choose, straight
Special Characteristics: Her eyes turn red when using her magic. She also has a photographic memory, avd remembers everything she ever sees down to the tiniest detail.

Personality: Rin is completely different from Saika. The two are like a yin to a yang, order to chaos, love to hate. You can immediately tell upon meeting the younger sister that she is incredibly intelfocused Just the way she talks and the words she uses oozes intelligence and an obvious different in understanding than Saika. Unlike Saika, who has a sort of split personality, Rin's personality is absolute. She's a cold, aloof, and calculated person, never not thinking before doing. She's the type who can almost seem to predict her opponent's moves, and uses her strong understanding of people and logic to achieve what she wishes, not sparing anyone on the way.

Rin is also very efficient and effective, wasting the least energy possible, at the fastest speed possible, with the best results. She is a genius when it comes to math, language, science, and history, her memory allowing her to remember everything she reads about the topics. You could tell out any random math equation or problem and she would give you an answer in a matter of seconds. Ask her any trivia about any facts, and she probably knows the answer.

What makes this even more effective is how calm and focused she is. She doesn't allow her emotions to get in her way, unlike Saika. Her focus on life is to improve, and become one of the strongest mages in Earthland. She also wishes to have seen every place in Earthland, so she can remember every detail and write the best book ever about everything she remembers about each place.

As for her relationship with Saika... Rin does know about her sister's sadistic, yandere side. Many of her childhood friends were all killed by the older girl, and for that, Rin utterly hates Saika. She would have killed her long ago, if it wasn't for the usefulness of having a bodyguard of sorts, no matter how creepy. She was focused enough to recognize Saika's use, and keeps her on.

Rin's life is basically controlled by Saika in every aspect, however, and she's never been totally and completely free from her sister's grasp. This has caused her to become extremely socially awkward and she can often misunderstand people. She isn't always the best follower because of this, doing her best to follow but often failing in her efforts. As a leader, she would be excellent, calm and focused, always with a plan in mind, if not for this social awkwardness as well.

In battle, Rin is just as cold as always. She's a thinker, using logic to counter attack and plan out the whole battle. Without her, the two siblings would have died long ago due to Saika's chaotic nature, but the two have learned to balance each other out.

To sum Rin up, she's a cold, calculated young girl who focuses on efficient and effective methods to get what she wants. Her life revolves around herself and her own goals in life, and she is willing to do anything to achieve them.
