Oblivionis Not fear of being forgotten

Lied, ignoring important details, spin the wrong, contradict herself all the time.

"Crychic? Mujica? Mutsumi? I don't know them" "I never said that" Episode 6, she said that to Tomori and Anon as she is emotionally in disarry

I have a lot of question for that

Ties breaker

She can cut away all relationship/contact with someone, all in sudden, and no explanation.

Hi Uika, with your help, I have forgotten everything, including you. After Ave Mujica disbands in Episode 4, Sakiko cuts ties with everyone in the band, even leaving Uika's residence with only a note that said "Thank you for everything." despite the personal attachment she had with Uika and Mutsumi.

Self-victimizer

She likes to play victim, thinking that it is someone else that wronged her. She attempted to gain sympathy/run from a blame, by hypocritically self-deprecating that excuse her own negligence and fault.

"I hate myself"...? Quote of episode 5. Chinese community has negative response on this quote. While she is emotionally devastated from her twice failure (narcissistic injury), Chinese community see she said such thing while in her mansion piano room, ride on a Maybach, and all the debt paid by her grandfather.
