They are all real tho... Each of the "personality" hold a role in their system. Basically they are like a glass that is shattered into pieces. Which of those frargments are the real one? they are all real. But I think rin is the host (the "personality" that fronts the most) while kazuha may be their protector or something.. it's a really interesting and complex disorder I would recommend you to watch Anthony Padilla interview with a person with DID. I learned from there (=・ω・=)
Oh yeah sorry I really did not know which word fits more. I was thinking of the “host” but somewhere in the manga the ml said “real self” so I went with that haha. Thanks for this tho! I’ll try to watch that :)
Kinda anxious who’s the real self. Looks like its Rin? Hahaha im fine with that but I kinda want to see more of Kazuha
