The ID Seraph can refer to one of two specialists:
The only child of a feared officer of the 54 Immortals, He Zhen-Zhen was raised within the ranks of the Singapore Quarantine Zone's ruling criminal combine.
She proved to be an excellent and dedicated pupil, learning the traditions and honored lineage of the organization while pursuing martial training with a single-minded determination.
She worked hard not to disappoint her father or the combine's leadership.
At 17, she was elevated to the rank of Enforcer, one of the few who police the combine from within while ruthlessly executing the will of the 54I wherever and whenever it might be required.
