片桐 一瀬
Katagiri Hitoha
An older sister of the protagonist. A cheerful and energetic person, but being abnormally interested in the sea, she could be described as a "sea maniac". She cared a lot about her brother. After their parents died, she replaced him a mother.
Seven years ago, she passed away on the SHEEP underwater expedition of an unknown cause. [i]Little did she know, to which nightmare many years later it would lead...[/i]
[spoiler]Her true name is [b]Katagiri Hitose[/b]. In the evening before the start of the expedition, she went for a walk with its leader, Ryuuzan Haruki, at the seashore. Here they have found Saihouji Rumi, bitten by an unknown creature and infected with the Alice virus. Although they had saved her, they too had become infected with the virus in turn. On the expedition, they fell into a deep sleep due to the virus's aftereffects. Unlike Haruki, Hitose has survived the tragedy, still sleeping. Four years later, she has naturally cured from the Alice syndrom. It was the first and only case of the syndrome being naturally recovered from. After the awakening, she got a connection with Saihouji. She learned to program and began her new life as a mediocre coder. Because of the aforementioned connection, she has become related to the SHEEPIII project. Her first role was to write its navigation program along with Nomura Reiri. After that, she made contributions to unforeseen situation avoidance systems. Katagiri Hitoha and Momoi Yukari were told that Hitose had died, so she decided not to reveal her survival to them. [i]That decision was a grave mistake—it has led to the SHEEPIII tragedy.[/i][/spoiler]
