Woah, with the speed they're doing the Mahouka Story they'll finish Volume 2 in Episode 6.
If they keep that up they'll end at Vol. 8 with the finish of the anime. Seems pretty fast for a Light Novel Adaption, even if Mahouka is a gold medal favorite for being an Infodump.
That would mean 4 arcs incl. Reminiscence. Quite a lot of stuff...
