For many to hear "School Days," the thoughts of the visual novel of the same name pops into mind. Regardless of "it's a generic title" or "it's pretty common" claims, the title will immediately be associated with Nice Boat, and the expectations therein.
Just deal with it. It's not your job to defend it.

With those sort of images, yeah. I can't help but think Nice Boat. And really, that screaming in the video? I doubt that's in ecstasy.
Nanoha (or Fate, or Hayate) is going to die. And I will
laugh.
