Yup, everything you need to understand what's going on.
Which isn't a lot, really. Most of it is unimportant, and the stuff about the ghost-girl dying from an experiment is nothing new. Oh, and she possessed Lenalee, and the three boys should now be zombies. Basically, Komui and Reever have to save the world.
On the bright side, the ending-text implies it might end next chapter. THANK GOODNESS.
...Actually, the end of Inuyasha was much more interesting.
