Spoiler alert, even for those who have played the original DS game. If you don’t want to to ruin the anime experience, stop reading right now.
From episode three onwards, Keita has disappeared from the ending credits. I only realised this at episode four (this is what happens when you keep replaying the awesome ED theme over and over).
Here is a screenshot of the ED from episode two. You can clearly see Keita in front of Hinako.
And now, here is a screenshot of the ED from episode four. Keita is missing, and Io is actually in front of Hinako with a lot of empty space in between.
What does this mean for the series? It means that my predictions are coming true: the show’s creators are not afraid to kill off the cast, and by the end of the anime we could see a lot more of those characters removed from the end credits. I am absolutely terrified for Otome now, one of my favourite survivors from the game who has a death clip of her own.
