Shisui Amamiya

Shisui is a calm and quiet girl, spending most of her time silently reading books. Shisui speaks with only a few words and fighting and obsessive training does not interest her, but she gets excited about history, culture, new knowledge and the bigger world, as she is naturally curious but is used to seeing the world from the distance.

Many viewed Shisui, as a monster for her strength, she was isolated for most of her life and now lacks most social skills, having gained most of her knowledge only from books, and wishes to experience the world on her own. Shisui is smart enough, that she could skip all her classes. She feels less confident in her ability to interact with people and be in social situations and fears not to be useful anymore and to be abandoned again, when she has found friends.

Shisui can also be playful, but this at times is overlooked as she does not emote much, so people struggle to notice when she made a joke. When she lies, she does a slight movement with her lips.

She is naive and tends to get tricked especially by mischievous characters in all timelines and even allows to be tricked just because she enjoys spending time with others. In all timelines, she is best friends with Fuuma Kotaro and is treated as part of the family, with Kotaro treating her almost like a smaller sister. Though, she wishes at times there would be more, she has been hesitant to voice those feelings and has been observant of other love rivals also struggling to get really close to Kotaro.

Shisui views herself as the protector of Kotaro and this belief only grew after the reset of her original world, in which her own memories remained, but she was turned into a specter. Shisui from this point thinks her and Kotaro's fate is linked, and his protection has become her key duty, but she resists to share knowledge about the past world and even details about herself, not to burden the current Kotaro. She also dislikes being called a ghost, and from time to time gets very sad, that most of her friends do not remember her, though she tries to keep this hidden.

She has made a friend in Koro Shishimura, which allows her to live through her, thanks to a body possession art. Koro trusts Shisui with her body but Shisui hopes to find some alternative.

Appearance: Shisui has white hair, pink eyes and medium-sized breasts. She usually wears a white leotard-like taimanin battle suit with long black boots and an open black jacket. Her ninja art, Wave Art, is a very rare nature based, ninja art that materializes the natural energy into the visage of a metal Guardian, which she can manipulate as she sees fit. This metal-like spirit being fights with its fists or is able to shoot natural energy. "Wave" refers here to wavelengths of energy and matter. Shisui is something alike to a spirit and requires the help of "Soul or Spirit Art" users. Usable past the reset of her original world, during which Shisui had been separated from her body. Now this spiritual form is active at all times, with no real body to return to. She can take a stronger form in Gosha Library. She can possess the body of her friend Koro Shishimura which allows her to live through her, thanks to a body possession art in order to have a physical form outside of the library.

Gosha Library is located in Gosha Academy. Holds numerous Taimanin books, Grimoires and documents and is protected by members of the library committee.

The Library seems to have some magical properties and is connected to the far past.

Though most only venture in the upper parts of the library if at all, the place goes multiple floors deep. Lower areas start to get labyrinth-like and dangerous, the place seems to be far older than anything above Gosha Academy and connects to a temple and underground city.

Build on top of an ancient ruin, that was worshiped as a place of the goddess of dawn "Ushas" and her descendants. In reality, the ancient family connected to the ruin turned out to be a group of pacifist Brain Flayers, which split from the Brain Flayer Conquerors Monarchy.

Around 10,000 years ago Marjaana took home at this place and used one of the Demon Gates to get to the Dark World. However, still travels to the temple city to rest from time to time. Eos became one of the guardians of the deeper ruin area that would attack anybody deeper. Marjaane group would later become one of the 9 Noble Demon Families even though they are not demons.
