Kyoko seems abrasive and selfish but has a somewhat soft side as well. She values food a lot and loves to eat. She may have experienced trauma from her family's death giving her an eating disorder of sorts, or erasing the memory of hunger. She is rather tomboyish, with barely any femininity at all if any. This is where she differs from Sayaka's boyishness, where Sayaka has a bit of a girlish streak in the fact that she is interested in romance, while Kyoko just about has a nice side, and likes stories with happy endings. (Doesn't everybody?) She is competitive and after her family's death was introduced to the principles of "Dog eat dog world", "you get what you pay for" and "Kill or be killed/Eat or be eaten" and started to live by them. She uses her magic and other abilities mainly for herself due to the belief that helping somebody else will only result in something bad. She is also somewhat arrogant. She seems to be very faithful in God as during her final moments in the original timeline getting killed by Oktavia (she does live in the world reconstructed by Madoka, but does not remember her), she prays to God to show her a "happy dream." . It's uncertain what exactly what this means, but presumably she is pleading to be shown something happy like her family all being alive and happy, in the form of a dream, or to allow her to die peacefully and ascend to Heaven.

Puella Magi Madoka Magica
Madoka Kaname and Sayaka Miki are regular middle school girls with regular lives, but all that changes when they encounter Kyuubey, a cat-like magical familiar, and Homura Akemi, the new transfer student. Kyuubey offers them a proposition: he will grant any one of their wishes and in exchange, they will each become a magical girl, gaining enough power to fulfill their dreams. However, Homura Akemi, a magical girl herself, urges them not to accept the offer, stating that everything is not what it seems. A story of hope, despair, and friendship, Mahou Shoujo Madoka★Magica deals with the difficulties of being a magical girl and the price one has to pay to make a dream come true.
