But they could go on a total limb and modify Sassy-chan's route accordingly to allow her that, it's not too far-fetched in scope than Kud's or Mio's. We could call it - her "unconscious guilt" manifesting.
I say Saya won't fit because a VERY major part of her route is "Guild hijinks" a la
Angel Beats! and so is quite an abrupt shift in mood and tone compared to the rest of the narrative.
Edit: And yeah, Sassy-chan has Common-route level comedy at the start, it was so refreshing to see Masato like that.
Also, does anyone have any outstanding fan-made videos pertaining to
Little Busters! they can link? Or is the well really that dry....?
