Sankarea 4: Undying Love

WE ALWAYS EAT THE ONES WE LOVE
 
A strange foreign doctor warns Rea that her "turbid period" is approaching... and that it will bring with it an insatiable desire to eat Furuya's flesh! Realizing she may not have much time left to live as a sane, normal girl, Rea works as hard as she can to enjoy her first, and maybe last, summer festival with Chihiro. But is it already too late for them both?!
