Did someone say KaiShin HeiShin?
*loves KaiShin HeiShin*
With that said I only manage to skim so here is what I think.
@Aeyra:
"She 'lost' her mom in elementary and is still trying to get her back whereas Ai didn't care much in the first place."
What are you talking about? Of course Ai cares about her mom! We had a whole file where Ai smiles so sweetly because she finally hears her mom's voice for the first time in 18 years! And I think Ai always cares about her mom even though she's so afraid. Everyone in the Org calls her mom "hell's angel". It was probably traumatic for her to think all her life that her mom was "evil" and that her mom never cared about her. She was so happy to know that her mother was a good person that cares about her, she listens to the tapes over and over...*feels like crying just thinking about it*.
@dreznovk:
"in fact, because Ran has too many good things about her without a noticeable flaw make me grow tired of her."
I don't quite agree, in comparison with other characters (Haibara included). I think Ran has most obvious flaws. The obvious one is that she doesn't solve every case with magical big brain powers or any sort of unnatural genius. She struggles with finding the culprit to "simple cases" just like a normal civilian human being with no training should be. She cries easily, she gets scared easily, she's unreasonable sometimes, she uses violence when things don't go her way and she's very very stubborn. She's not the prettiest one, she doesn't have the biggest bewbs eva, she likes boy bands unreasonably just like every silly teenage girl, she's kinda slow (she has her hillarious derp moments), not that witty (she can't tell Sonoko or Shinichi off like ever), and she doesn't understand relationships yet she believes in teh powa of loveee (unlike me).
I'm really not sure why people think she's perfect Mary Sueish at all. Sure she's KIND, but then everyone in the DC world is kind, Heiji, Ayumi, Haibara, Conan. I do think she's unique though. She's a kind character WHO IS NOT BRILLIANT and cannot think of 10 different awesome ways to stop a bullet. She's not afraid of looking stupid, she can only do what her instinct tells her. That's what makes her so unique to me. She is a normal kind girl in a world full of genius villains and genius detectives. Yet she tries to hard to protect everyone her own way.
