Your hide betrays your name, but there is something in your heart that comes quite close. The name "Kiara" = black, dark. She is red/white. However, she is "depressed" as noted in her personality, and depression is often referred to as a "dark" time/feeling.

You betrayed yourself once, letting your dedication falter. History reference & Personality Reference: After hearing Sun God and Spark God talk she doubted her loyalty to the Moon Goddess, which betrayed her loyal personality.

Such a shame that you don't know the bastard that planted you. Father = unknown.
+1| Easy enough history clue- good!
2/3 for me- Fail
