Luo Yifang then forced a receptionist to take him upstairs, leaving Okita to defeat the security forces and heroes who tried to stop them.

• A receptionist dismissed Luo Yifang and Okita Souji until Tatsumaki arrived, recognized Luo Yifang’s stare, and found that her psychic powers could not move him.
