Atsuko Sasaki

Sasaki Atsuko, commonly known as A-chan, was Katarina's best friend in her previous life.

History
In elementary school, Atsuko was often teased, ignored, and had her stuff hidden. She was kept out of the loop by everyone and this caused her to become recluse and afraid of other people.

At thirteen, she enrolled in a local middle school and nothing had changed despite it being a new environment. Instead, Atsuko spent her days reading all kind of books as an escape for feeling lonely.

Her daily routine stayed the same for weeks - going to the library to borrow books after homeroom, changing her shoes at the shoe lockers then cutting across the courtyard to head for the school gate.

However, after seeing other girls chatting while crossing the courtyard, thinking how nice that would be, Atsuko was hit by something with a tremendous impact and instantly fell unconscious.

It turns out that a person fell on her. The person being the previous reincarnation of Katarina. She apologized, saying that the charm of the tree was too strong that she couldn't resist and that her foot slipped.

After ensuring the girl that she was fine, it turns out that they were in the same class despite Atsuko not knowing who she is. She introduces herself (although does not reveal the name) and before Atsuko realized it they became friends.

Before Reincarnation
Both Atsuko and the girl were otaku and worked in a part-time job together. She would always support her whenever she forgot her homework and thought that her days would always continue like this - full of life and energy.

However, that girl was absent from school one day. But Atsuko didn't think much about it until she found out after school that she took all the days for granted.

She couldn't believe what happened and held onto the hope that she would return. The days went on normally and looking at her messages, one was unread and sent by her best friend. It was sent in the middle of the night on the morning she died, the message was:"'A-chan. I'm having trouble capturing the sadistic evil prince~”"Atsuko finally cried and accepted the truth that the girl would never return. She wished that when her life is over, she could be reincarnated into a new life with that girl and be friends again.

Reincarnation
Atsuko's memories of grief return to Sophia as she and Katrina's friends grief as they worry about losing her when being put to sleep for two days.
