Ruri has shown a few sides of her personailty that could be considered contradicting. she is very knowledgable in matters conserning business as she is able to manage her families corporation, serious when fighting the dark stones, naive when it comes to mundane matters like what the pinky signify in japan (this was humorously shown unowingly admiting that she was Alma's girlfriend as she said "she was his" and raising her pinky finger) it is shown a few times that she can have a stuborn streak. During the rest of the fewer wars, Ruri is determinable to protect humanity by helping Alma Tandouji just before the saving the day and the rest of the world. She very supportive, protective, and diligent to help the Alma Tandouji to be a true hero in case of an emergency.
