At first, with Ghost in the Shell_2045, Purin Esaki was a character who got on my nerves... but after having watch the Season 2, and know more about her background, I began to appreciate her more and more! So, I remember in the episode 4th of the Season 2, Tachikomas were talking about her member family and we could see their name.
So, I tried to translated them to know Esaki's last name, as well as their parents' and her sister name. I'm not talking or learning japanese (so if there's any mistake, I just did my best as even the japanese result couldn't give me these information) I think I greatly managed to know "approximatively" their name despite the blurr picture! *remember, we're in 2045 in GitS*
