The Rising Of The Shield Hero: Raphtalia (Figures)

I seriously recommenced you guys watch this anime it's pretty damn good despite a few issues but I would say it's my favorite anime of 2010s.

3x3 Eyes: Pai Ayanokoji

Pai is the star of 3x3 Eyes and The last surviving Sanjiyan Unkarat. Pai can absorb a human soul to do her bidding, transforming the person affected into a nearly invulnerable servant. She has other mystical powers usually manifested along with the appearance of her third eye, and used by her Parvati identity. Older Sanjiyans often become evil, decadent and uncaring; younger ones tend to have split personalities. Three hundred year-old Pai is an example of a younger Sanjiyan: her Pai personality is somewhat flaky, but caring and cheerful, while her Parvati personality is more arrogant and ruthless. The two personae are aware of one another, and sometimes talk between themselves.
