Physical Description: Kairi has semi-long, pitch-black hair that she often styles in a ponytail, brown eyes, a fairly thin nose and thin lips. Her ears are on the smaller side, but still quite average. Her skin is very pale and she definitely has inherited the more 'asian' connotations of her Japanese mother. She is 1.42 meters talls or about 4 feet and 8 inches.

Mental Description: Kairi is of kind nature, she likes helping anyone she can and tends to be open to feedback, albeit only if she respects whoever is giving it to her. Initially, when she first meets someone she can be quite shy, but even in her young age, she shows quite a strong personality once she feels comfortable enough. Particularly, she's quite proud, and when she's convinced to be right, she'll stick to her opinions and can even seem hostile if constantly confronted about it. Mostly, however, she does her absolute best to avoid conflict. She also values a lot what others think of her, and does her absolute best to appear amazing in front of the people she cares about and, to an extent, even in front of the people she doesn't care as much about. On top of that she's quite ambitious and has great expectations from herself, to the point that she has a lot of trouble dealing with failure.
So, while she's always willing to lend a hand, and does believe a lot in the power of cooperation, she can sometimes be selfish, mean, when she's too proud to admit a mistake or too convinced about the rightfullness of whatever she's doing, making her seem quite unpredictable at times.

Biography: Kairi was born in London, when her Mom and Dad were respectively 34 and 39 years old.
Her Dad is a mage who was born in France, but already lived with his family in London when he got his letter of invitation to Hogwarts. Now he works in the Ministry of Magic, under the department of Magical Accidents and Catastrophes, in the Muggle-Worthy Excuse Commitee, after developing a passion for Muggles during his permanence at Hogwarts, despite being a pureblood himself. Before working at the ministry he had decided to start living amongst Muggles and travel the world. As he remained in Japan for a few months, he met Kairi's mother and as Fate intricated its wires, they ended up marrying, living together (in London) and giving birth to a Baby who ended up having such an uncommon name, despite never having set foot outside of England in the first 11 years of her life, Kairi. With them, the girl had quite a happy upbringing. During her early years she grew up like a Muggle through and through as her Father kept his magical background a secret to the family for quite a long time. In fact, he was only forced to spill the beans once, during an argument between young Kairi and her Mother where the former got angry, setting fire to some flowers in their garden as she yelped in her rage-filled cry, he had to react quickly, defusing the situation, extinguishing the fire with a bucket full of water, and explaining what just happened to the, luckily, only witness of that peculiar situation: Kairi's mother.
And so, in the past three years, since then until now, both Kairi and her mom had to accustom to the fact of being part of a magical family, as they both simultaneosly learned, albeit the former with greater detail, about Hogwarts and what would happen when the girl would've finally turned 11. She learned about the Houses, the Subjects, the Spells and grew more and more excited of attending that magical and, in her mind, amazing school.
