Sasami Tsukuyomi is the main character of the series. She is a high school girl who used to be a shut-in and only started going to school in her first year, February. She lives in Amanomahoko Town with her older brother Kamiomi Tsukuyomi. Sasami says she does not like her brother but actually relies on him a lot in daily life. She has a strong personality with two sides: she can be very sweet, but uses rough words when she gets angry. Sasami was once the "Priestess of Tsukuyomi" and carried the "Power of the Supreme God," but she ran away from her duties, choosing not to push herself anymore. As the story goes on, she learns to balance doing her best and relaxing, makes close friends, and even shows signs of developing crushes on her female friends.
Sasami is a girl with fluffy, wavy hair.
She is a student in her first year (Class 1-R) at Sakura No Hanazakuya Academy.
In later books, she moves up to the second and then the third year.
She is often seen wearing her school uniform.
Sasami is a serious shut-in and had trouble even stepping outside her home.
When she tries to leave, she sometimes gets so scared she throws up or faints.
She watches her brother from her room using a tool called the "Oniichan Monitoring Tool."
Sasami depends a lot on Kamiomi for everyday life.
Even though Sasami often doesn't want to try hard ("not doing her best"), she sometimes wishes she could go out and make friends.
She spends thousands of hours playing online games, but deep down, she's a warm, loving person.
When she gets mad, her language gets rough.
Sasami can also be sweet and is very affectionate, especially with people close to her.
Sasami lives with her older brother Kamiomi Tsukuyomi in Amanomahoko Town.
She stopped going outside and to school for a long time.
Her daily routine was spying on the world outside—especially Kamiomi—through her computer.
She got deeply into the online game "Yamata no Orochi SNS" and spent thousands of hours playing it.
All this made her a typical shut-in and online game addict.
Sasami is the "Priestess of Tsukuyomi."
She was born in a family that carries the power of the Supreme God, called "Amaterasu," from Japanese myth.
As a child, she worked very hard to help the world by using this power.
She thought that the power had moved to her brother, so she watched him carefully with her tools.
In truth, the power of the Supreme God never left Sasami—it always stayed inside her.
The strange things that happened, like the "Chocolate Incident" or the rampage on "Yamata no Orochi SNS," were results of her own unconscious power.
Sasami is very close to her brother Kamiomi Tsukuyomi.
She acts like she dislikes him, but cares for him a lot.
She quickly gets attached to her friends, especially Kagami Yagami and Jou Edogawa.
Her closeness with Kagami leads her classmates to think they are dating.
Many classmates decide to quietly watch over the two of them.
This special friendship sometimes makes it hard for Sasami to make other friends.
She also has a soft side when it comes to her mother, Juju Tsukuyomi, who came back from the land of the dead.
