[Hagoshod]

Spoiler:

- Three books long.
- Mami dies at the end of book 1 in a way that unlocks most of Madoka's God powers early on.
- Madoka gets a new Magical Girl form at the beginning of book 2, but it's just a white and purple palette swap of her original one.
- Sayaka and Kamijou allow their relationship to develop and regularly have sex. Sayaka gives Kamijou a clipping of her pubic hair to keep as a memento (it's a weird Magical Girl tradition) before she meets her human end.
- Halfway through book 3, Madoka discovers Kyubey is the source of all problems in the world. She tries desperately to convince all Magical Girls and Witches to stop fighting each other and unite against him. A really dumb trigger-happy rookie Magical Girl inadvertently kills her in the process.
- Madoka's ghost astrally projects herself to appear to all the remaining characters at once. She breaks through mostly to Homura, who takes up the flag and leads the united front against Kyubey.
- Magical Girl + Witch team invade the Incubator home world and unsurp their government. Homura kills Kyubey by dropping his primary body off the side of Walpurgisnacht.

Those are just my theories.
