Kimiko Himura/Karin Himura

Appearance
While Karin may be far over 400 years old, she both looks like an eight year old girl and has the biology of one. Karin is the shortest and smallest of the three Personas making it very easy for people to treat her as a child instead as the powerful demon that she is. The fact that her facial expression and body language seems to emanate naïvety doesn't make it any easier for people to not treat her as a child. While most other people would get upset when treated this way, Karin seems to not mind at all. In fact, one can argue that she loves that kind of treatment.

The first thing that people notice when looking at Karin is that she has a small grey tail. This trait is what separates her from the other Personas since the others lack a tail. The tail has a lot of similarities to the tail of a puppy as it is small, only a couple of inches long, and the fur on the tail is extremely smooth. Just like a dog, her tail responds to her every emotion, making it very easy for people to tell what kind of mood she is in.

Personality
While Kimiko and Miku seemed to mature over the years, Karin's maturity hasn't changed in the slightest since she was eight years old. This gives her a personality that most would describe as "puppy-like." Karin seems to find everything fascinating, even the most simplest and insignificant things. This is most commonly seen when she displays her seemingly euphoric reaction when she is given a single bread crusts to eat. This attitude makes Karin extremely easy to approach because she never sees the bad in people, but instead she always sees the good. This trait is possibly why Kazuma doesn't hate Karin, despite the fact that she is one of Cerberus's Personas.

This comparison of her to a puppy also comes from how hyper she is. The combination of this trait to her fascination to almost everything makes it seem as she has an endless amount of energy. However, just like puppies, after a long day she will fall asleep almost immediately if you put her in a soothing setting. This will happen even if she still seems awake and active.

Relationships

 * Kazuma Himura: Out of all the other Personas, Karin is the only one who shows any kindness to Kazuma. As a result, Karin is the only Persona that Kazuma doesn't completely hate. This lack of hatred, has caused Karin to develop a very close friendship with her younger brother that none of the other Personas have. How close she is to Kazuma was revealed when she mercilessly slaughtered Hercules after she heard what he did to Kazuma. Once he was dead she ripped him into thousands of tiny pieces with her bare hands and spread those pieces all over Earth Land to make sure he would never come back. According to Miku, Karin was so angry that Karin didn't even have to think about killing Hercules before killing him.

Amplifier

 * Demon Shockwave: Karin makes a flicking motion with one of fingers. As she flicks her fingers, she charges magic power to the kinetic energy that makes up that motion. This causes the kinetic energy to increase to the point that a powerful shockwave emits in a forward motion from her finger. This shockwave is capable of travelling across large distances and it is strong enough to destroy several buildings in a row.
 * Devil Cry: Karin lets out a loud yell as she charges magic power to the sound waves that make up the yelling sound. This causes an increases in how loud the yell is drastically. The sound waves become powerful enough to destroy a target's eardrums and substances like crystals such as ice or glass.

 * Personas: Persona is a very unique ability that only Cerberus possesses. As stated above Cerberus has multiple human appearances, each with their own personality. These appearances are called "Personas". When Cerberus is in her human form she switches between Personas when she hits her head with great force. However, the mechanics behind this is a lot more complicated. Cerberus is widely known for being a hellhound with three heads. While Cerberus is in her human form, each head has its own soul. While in human form, two souls are dormant while one of the souls controls the body. When Cerberus hits her head one of the dormant souls and the one active change places. When the previously active Persona becomes dormant, the soul is transported to a part of Cerberus's consciousness that serves as the holding place for dormant Personas. This causes the bodies appearance and personality to change into the human form of the other head. Since each Persona has a separate personality, they also have separate memories and the only time they share memories is when they are in their demon form. Since they have separate memories they use different magic while in their human form. Just like with memories, when they are in their demon form Cerberus can use each one of her persona's magic.
