Sakura

She was born with the ability to tap into the "Limpid Channel", allowing her to pick up the waves of consciousness in the air around her. By picking up the random thoughts of other beings, she is able to give useful, seemingly precognitive, information, though often in a cryptic manner. However, she was also born with extremely poor health, and she spends much of her time confined in a special chair, known as a "Manage Machine". Although she is a Dual Kind, she only is used as a Head Diver in emergency situations, due to her weak constitution.
