Episode 15 follows the reporter we see from previous episodes. Mika Haruna’s (did I get it right) father. He visits one main character to another until he gets turned into a freakish mindless zombie who just won’t die. Little too late to give a spoiler alert, but I think that it is pretty self explanatory to watch anime before you read someone’s take. If you just wanted a gist of it like “it was good.”, then I suggest you go read RC instead.
Raise your hand if you think she is creepy!
