No one can understand how it activates, i only know it has something to do with the dice and walls.

I noticed you don't have a page on Ritz Kobayashi:

All I could find so far was she was borne in Komba,Meguro,Tokyo.

She was raised in Ettyuuzina,Koto,Tokyo.

Series worked on:Fatalizer,Saki,Saki Achiga-Hen Episode of Side-A.

I saw a photo that might be her,but I can't confirm it.

Source:Baka-Updates Manga,AnimeNewsNetwork.

Can anyone add or confirm any of this.

The one who's in apparently in a wheelchair, in the flashback that happens on the dock. She's also seen with Saki and Teru in a picture. A childhood friend of the two, probably somehow responsible for the current relationship between Teru and Saki? I think there's also fire shown in the flashback, so something must have gone wrong.

I haven't found any other information about her, is there any out there? If not, any speculation?

I was reading the manga in japanese and I noticed fails in someplaces, like, when in the start of the manga Saki has more than 14 tiles (I don´t remember how it was, but I was shocked). Or when in manga book 6 (anime ep. 16) Koromo has three North Dora, because she made a North pon, and the dora indicator is the fouth north. When the dora indicator should be West Wind...

Now that Achiga has ended, Ritz and Igarashi are starting a new series. What do you think this new series will be about?
