Okita Souji Alter

Okita Souji was a member of the Shinsemgumi in the mid-1800s and was excellent swordsmen in her group, becoming a captain of the first unit at a young age. Unfortunately, Okita would soon die due to having tuberculosis. However, this Okita fate would differ from the original. Due to being born premature, Okita would die soon after being born, but her sister prayed that Okita would survive. Thus, the Counter Force made Okita into a Gaurdian. However, there were a few issues with Okita because she became a Gaurdian at an infant, her mindset would be that of a learning child despite her mature appearance. The bigger issue is that Okita is only meant to be a one use servant, meaning her Spirit Origin will burn out once she has completed her mission and dissappear forever. After resolving the Imperial Holy Grail War set in Tokyo 1945, Okita mission was completed. Rather than disappearing like she thought, Okita would be given a new mission by the Counter Force, which was to aid you on your mission to restore humanity.
