Brief description of the head cases and voices
Izayoi: Calm, aloof, observant, calculating and sharp tongued, very obscure in personality and generally enjoys being an enigma or being overly obvious and playful depending on her mood. Veterenary surgeon and active in three kinds of martial arts in addition to going to school.
Riloyss: Calm, observant, studious, dry sense of humor, strategic, serious, generally the voice of reason in the group and has the biggest sense of responsibility and a quiet aura of leadership. A wizard who specializes in Illusion and one who walks the Ruins.
Sekai: Quiet, shy, humble, Timid, Melancholy and Pacifist, generally tries to keep everyone getting along or preventing fights. Also loves a good book and tends to keep things to herself, too humble for her own good and is respectful even to those who she winds up in battle with. A third year student in senior high school and Archer in The World.
Kira: Wild, Outspoken, Opinionated, Manipulative, Calculating and Sharp Tongued, rather distainful and mistrusting of humans and rather enjoys fooling them into believing she's something she isn't just to see if they buy it. Hides a calculating and rather surprisingly strategic nature in addition to an insecure side behind the facade of always messing with other people. Daughter of a Sea and Ice Goddess, Long Arm and AI in The World.
Sakura: Strong, Powerful, Willful, Stubborn and Tempermental, generally the strategic one and one of the most intelligent from her village. Powerful medic and impressive control and timing of her chakra. Prone to having tempermental fits at the sight of idiocy, she has her moments of weakness and regret, though the spirit shines through and she refuses to give up until she's completely defeated. Member of Team 7 and Tsunade's Apprentice.
Kagome: Headstrong, Willful, Responsible, Friendly, Tempermental; generally the voice telling people to listen to their hearts and the one who tries to heal the wounds and scars from the past. Hopeless when it comes to her own situation and confession of feelings for Inuyasha but still manages to come off as fiercely loyal to her friends and loved ones. Powerful inner strength and heart with a warrior's spirit and a somewhat naive view of the world. Reincarnation of the last priestess of the Shikon no Tama and a third year junior high school student.
Natsumi: Aloof, Cold, Determined, Focused and Willful; generally tempermental but has her moments of cold logic and believes firmly in realistically taking the facts into her own hands. Prime canidate for a missing-nin... though her specialties lie in herbal research, senbon and kunai use; poison has become a favorite and she mercilessly kills her enemies without remorse. Only female of an all male clan and reckless but calculating shinobi of Chuunin Rank.
That's basically them, I'll do more information on them all later, more extensive backgrounds and such in their personalities.
