Kira Daidouji (大道寺 きら, Daidōji Kira) is a playable character in the Arcana Heart series. She's a young genius with a PhD who is plotting for world domination. She is an associate of Mei Ling Hua and knows Mei-Fang pretty well. She also attended the same school with her friend and rival, Catherine Kyoubashi.

Her Arcana is Niptra, the Arcana of Water.


A genius who gained her PhD at the age of eleven. After she was sent back to Elementary School, Kira has become bitter with the world and plans to conquer it. The blob she controls is made of ether and can modify itself to suit whatever she may need.


Kira is a fair-skinned young girl with goldenrod eyes. Her hair is dark blue and worn in a loose bob with spiked bangs spread out above her eyes, along with hair intake on the top of her head that resemble cat ears.

She is often seen with a confident smirk or grin and is always depicted in a navy-blue school swimsuit. But she can also be found in a towel or a white lab coat on occasion. 


Kira is a girl with a high opinion of herself and a low tolerance of anyone else. She possesses zero social skills and has become very arrogant and snide towards everyone else and the world after being sent back to school due to her age. To those she may respect or even consider friends, she can be grudgingly open and sincere at best, and to those she doesn't care for she can display almost comical amounts of abuse and scorn.  

She has a quick-wit and short temper, and has no problem gloating or mocking those who lose to her, along with boasting about her greatness. However, it is suspected that deep down she genuinely would like to have more friends or to be better liked by others.
