Transplanted from the mass thread ages ago, and somewhat updated with new people. If you're not on here, reply and I'll put you up.
Alkaid - She might have felt bad for her, knowing that she goes into a coma, but Alkaid's simply fallen under the "brat" category and seems irredeemable. Her lack of respect and even common sense get right under Pi's skin in the worst of ways. While they're both headstrong, it's in completely different ways and Pi just can't understand why she does what she does.
Angra Mainyu - She really doesn't know what to make of "Zero". She finds him to be crass and rude - he's too old to be considered a brat - and the mistaken identity thing didn't really help. The "Avenger" thing kind of bothers her, though she'd never say anything about it. His style of thinking and debate irritates her logical, direct mind, though she would rarely let that irritation show.
Anise - Due to circumstances in their first interactions, Anise got lumped into the "brat" category. Pi finds her disrespectful and juvenile to a fault. All Anise has to do is show up, and Pi will go into angry mode. It doesn't take much for Anise to wind Pi up, and the fact that Anise tends to go for low blows during arguments doesn't help matters. Even if Anise was to somehow become nice, Pi wouldn't trust her further than she could throw the island. It would take some drastic changes to get her opinion to change.
Atoli - Even though this Atoli never experienced anything from the time period Pi came from, she is still concerned about her. It's a bit frustrating that this Atoli isn't the one that stood beside her during the Sakaki battle, but at the same time Pi can see the potential there. Pi interacts with Atoli hoping to bring out that potential - and besides, deep down she does care about her. She'd never admit it though.
Dahlia - For the time being, Pi simply thinks of Chinami as a naive and fragile little thing. However, Pi doesn't really feel compelled to protect her or even go out of her way to assist more than idle comments. This is mainly because she sees Chinami as being "too sweet" and doesn't trust something that's that nice completely. This is more because Pi's a girl and Chinami's butterfly power can't work on her. XD Defunct due to drop.
Edgeworth - Ohhhh boy. She does have a good opinion of him, actually... he is a nice person. She's just not sure about much else since they avoid each other like the plague ever since the Moe Note happened.
Endrance - Not much of an opinion as she doesn't really interact with him, though she finds him frustrating to deal with when she must. Defunct due to drop.
Gilgamesh - She really doesn't know what to make of him. She's more confused than anything, especially at the idea that there's someone from another world that looks like her. He seems nice, although a bit confused. However, unlike most people here, he did not come off as brattish, and thus she doesn't actually mind him (gasp). She probably wouldn't have a problem with him, he seems suitably respectful. XD
Haseo - He's still a brat, but he's slowly getting better. He's definitely got his first entry into Pi's good books, but there's still a long way to go. She trusts him, but at the same time she still sees him as lacking and needing a better sense of direction.
Kaworu - Kaworu bothers her because he knows too much, and he's waaay too nosy - he violates the personal space bubble you could say. The fact that he's talked to Ovan just stacks things against him. She tolerates his presence the same way she tolerates most others', but she doesn't trust him.
Kuhn - Even back before the island stuff happened, Kuhn was one of the people she was closest to - second after Yata himself. Due to the danger of their line of work, after Kuhn proved his skill, she trusted him with her life in a professional capacity. Since their interactions took place while she was working, she associated him with her "professional" life, and thus that was how she presented herself to him. Apart from all the beatings when he'd go out with girls instead of working, of course.
Of course now that the island thing happened she's at a bit of a loss since now there's no professional and everything's encroaching on her personal life. She still trusts him, but it's hard to figure out the capacity anymore since there's no ties of work holding them together. He's like a comfortable presence in a sea of madness - an infuriating presence at times, but something familiar.
Reborn - He's good to talk to (someone else using earth logic!), and quite insightful. She tries not to let his youthful appearance get to her, since it's rather odd for a baby to talk with that sort of demeanour. She's not sure what his Mafia connection means, but for the time being she has no problem speaking with him, and enjoys most of the conversations.
Touya - Akira is probably one of her favourite people on the island because he makes sense. They are somewhat similar in a few ways, more notably both being workaholics (over games, no less) and logical thinking, so she finds him easy to understand and interact with. Go time is probably one of her favourite times, as she uses the practice as a break from the general insanity of the island.
Zefie - Zefi is special, as not only is she a brat she's an AI brat. That means she's interesting and disliked at the same time. Which side comes out more depends on the circumstances though. Still, just because Zefi's an AI doesn't exempt her from the brat label, and Zefi's even worse of a brat because of her abilities.
