Damn, when Sayaka was saying that things looked too bright, I was despairing that they were going to bait and switch. But nope. In reality, I was really hoping this happened in the anime. When they were calling out and Sayaka's silhouette flashed for a second, I wished for this and it never came.. Glad to have read this.
Eh. WAFFy endings just sort of negate the appeal of PMMM. Tragedy is an essential part of the story; the depths of despair reflect the shining heights of the climax. That contrast is what makes PMMM so appealing.
