葛ノ葉 チトセ

Chitose is a net idol who Towa and Haruki are following, and she is the individual who provides Haruki with the invisibility drug. She generally acts bright and cheerful, though occasionally foul-mouthed. However, underneath she is desperately and utterly lonely. In actuality, Chitose is well over a thousand years old, having taken the invisibility drug in her own past, exiling herself permanently from human contact. This is because the drug's true effect is to make the user impossible to recognize even if they are in front of them, rather than simple invisibility. In the distant past, Chitose was Empress Regnant of a small nation and used the drug, received from a sage, for stress relief. At the end it is revealed the drug she took is canceled and she has reverted back. At the end of her route she is revealed to be engaged to Haruki and she has became Matsuyuki Chitose (待雪 チトセ).
