It lists all the media available by order of release and also lists all the separate series in this series (series within series). There are no official English translations available, but there are fan translations of some (not all) of the material.

There is no anime. There is an ongoing manga series, but it's dedicated to one story arc in the series as a whole (that being The Daughter of Evil)

Something to understand going forward is that this is a franchise with one whole cohesive plot, but it's split up between different series and stories that all take place in the same world. A lot of things are highly contextualized and you won't understand everything immediately.
