It's difficult to judge the Grisaia anime for what it is rather than for what it should be, considering nearly every issue is in some way related to the pacing. The characters frequently engage in acts of nonsense because the anime doesn't have any time to explain their actions. Sachi's episode is just laughable as it immediately transforms the naive, innocent maid into some dangerous psycho without any reasons as to WHY. A few minutes later and again without reason, she changes back into Stupid Lovable Sachi, and at that point it becomes a mystery who or what her character is even supposed to be.
