12. Kokonoe observes Hakumen for a short time in BBCS. Else, Hakumen could not exist in the world(though he switches to Rachel). That's what his Calamity Trigger story(besides meeting Ragna at the Cauldron) was all about.

13. No comment on that. All we can do now is guess, so answering Ixy's question right now is quite difficult.

18. Read BlazBlue Phase 0. Ragna was sent to 2106 AD into the past after Nu jumped into the Cauldron with him. Nu already became the Black Beast by fusing with her Blazblue and Ragna's one at that time, while Ragna suffered from amnesia. He travelled with Caelica(Nine's sister/Kokonoe's aunt) and Jubei(known as Mitsuyoshi) to Japan and regained all his abilities and memories once he met the Black Beast. However, he immediately noticed the time paradox and when Jubei asked for his name, he only stated that his name is "Bloodedge".
