As this series opens Ton Baileu and her friend Shinyao Mu arrive in London. Almost immediately they are robbed and as she chases the thief Ton finds herself in Café Forbidden, an establishment originally set up by her great grandmother. It stands on the border between the worlds of humans and shadows (supernatural beings). Not long afterwards Shinyao is kidnapped and Ton finds herself working alongside the Café's staff. These are members of Twilight, a group who want humanity to be at peace with the shadows.
This series was decent enough even if there are already plenty of anime series featuring supernatural beings. When the friends arrive in London we see plenty of little details to suggest the makers did their homework rather than just including a few iconic landmarks. Ton is a good central character and there is a sense of mystery about her family's past which provided extra interest. The antagonists are a little cliché and thus rather forgettable... as I fear the series will be before too long. Overall not a must see but it passed the time well enough while I was watching.
