Kyubey. I wouldn't say I love him though, it's more like I just don't despise him anymore.

I initially didn't care much for Kyubey but he eventually grew to be one of my favorites from the series.

I used to hate Kyubey but now he's alright, and I also used to be neutral on Madoka but now she's my second favourite!

I used to dislike Sayaka, but now she's almost my favorite! Right up there just behind Homura. Kyoko remains first though. I liked her from the start!

I loved all the characters at first, except for Homura and I still don't like her.

I didn't like Homura too much at first, but she's now my second favorite.

Kyouko, at first I said: "You're a b****!"
Chapter of her death: "NO KYOUKO NO WHY NOOOO!"
And I don't like Homura a lot. At the beginning and in the ending. I like her, but not "a lot".

Spoiler alert:

At first, I don't like Homura because she is a b****!

I like Madoka, Mami, Sayaka, Homura and Kyubey at first. Because all the 4 girls are friendly, I love these kind of girls. I cannot see Kyubey doing bad at the first 5 episodes.

And I saw Kyoko for the first time I'm neutral towards her. After episode 9, I start to like her because Madoka tell Kyoko she will help Sayaka because Madoka is Sayaka's best friend.

In episode 5, I started to dislike Madoka because Homura said give up on Sayaka, Madoka cried.

In episode 6, Madoka threw Sayaka's soul gem in order stop her fight with Kyoko. Unfortunately, that left Sayaka lifeless because Kyubey didn't tell the important things about soul gems. I am very crossed with Madoka as well as Kyubey.

In episode 7, I started like Madoka again but started dislike Sayaka as well as hate Hitomi and Kyosuke, The event left Sayaka broke down to the following episode. In episode 8, I hate Sayaka because she told Madoka something which hurt Madoka's feeling. As a result, Sayaka's soul gem is seriously corrupted and turn into a witch a died at the end of the episode.

In episode 9, I started to like Homura because she took care of the fainted Madoka. In the end of episode 11, she managed to reach to the Homura's sence. In episode 12, Madoka became a magical girl and decided to fight Walpurgisnacht. Saving everyone (including Homura). Madoka also transform in to Goddess and killed her witch form.

My ranking after episode 12 before the 'Rebellion' movie as follows:
1. Madoka
2. Kyoko
3. Homura
4. Mami
5. Sayaka

I miss Madoka after watching episode 12. At first, I think she died, later find out I was wrong. She still exists as "Law of the Cycle".

In 'Rebellion' movie, I started to love Madoka and Sayaka even more, Madoka regained her confidence after becoming a magical girl. She was not a crybaby anymore. I did not see Madoka crying in the movie, which is completely different from the original anime. (Many fans complain Madoka she is boring, useless and a crybaby in the original anime) Sayaka summons her witch self Oktavia and an army of familiars and control them well unlike in episode 8 and 9 as well as timeline 3.

My final ranking after 'Rebellion' movie to the end as follows:
1. Modoka
2. Mami
3. Sayaka
4. Kyoko
5. Homura
6. Junko
7. Nagisa
