Okita A (Taimanin)

Okita Souji Alter is a special Servant who became a Guardian for the Counter Force to eliminate those who are threats to the planet. While she was originally supposed to be erased after completing her mission, she was granted a new life and became your loyal Servant. When an unknown Singularity appeared on Chaldea monitors, you and Okita were assigned to investigate it. However, this Singularity turned out to be a completely different world set in the 2070s and full of Demons who attack humans.
