Those born under Cancer are extremely nurturing. They tend to be extremely traditional and emotional and stick close by their family or memories of their family. This leads to a desire to propogate the family line and sticking close to their roots. Beings associated with the crab, Cancerians live their lives with a shell around themselves; retreating into it when moody or feeling vulnerable. However, they are the first to express their emotions whether happy or sad. But despite this, those born under Cancer tend to have a strong willed persistance. However, they also are skilled at the use of emotional manipulation in order to get what they want. Despite this, they are generally pasive and gentle, but protective of loved ones with a strong intuition. If you're working in a group, let a Cancerian handle the funds; they don't waste them on frivilous things.
Virginia Maxwell (Wild ARMs 3) 7/6: If you want to talk nurturing, look no further than her. She's forever taking care of other people; indeed she started her quest to help those in need. But her biggest pet project is Jet, who she wishes to help find his past, and then find a place in the world. Because her parents died when she was small due to the Yggdrasil incident, she is forever thinking of them and wishing to find answers to what happened to her father. Indeed, when she's upset she retreats into a shell and thinks of her happiest memories. You always see her showing her emotions throughout the story. However, no matter what she persists in going forward and doesn't take "no" for an answer when Jet complains about something, sulking when he doesn't respond.
Rutee Katrea (Tales of Destiny) 7/19: Because she was left in an orphanage after her father became possessed, Rutee is extremely understanding and nurturing of her fellow orphans; risking her life so that she can pay off a debt and keep the orphanage open. When angry at someone, she tries to form a wall to keep others out; especially the overly helpful Stahn Aileron. Finding out her past in the second half of the game leads to her grasping for the memories of a family taken away from her by a wicked plot, a strong will to avenge both her father and brother burning in her soul. She pushes forward with her will no matter what the circumstance, only crying at two points in the game but recovering when she needs to fight. Considering her position on gaining money for the orphanage...I'd say she'd be pretty responsible with and not waste it.
Culotte (La Pucelle Tactics) 6/24: Losing his parents as a child, he is extremely close to his older sister Prier. Despite being only twelve years of age, and not really a strong fighter, the boy wishes to have the power to protect her, fearing being left alone all again. He gets extremely emotional over various situations, sometimes overreacting or jumping to conclusions about others' motives (especially Croix when he appears to be acting chummy with Prier or Alouette).
