New chapter is available at Onemanga.
Akamatsu-sensei does not seize to amaze me. I was kind of afraid that the story might get slightly cliched after Negi's arrival to Fate's castle (i.e. beats Fate and other bas guys, gets ahold of the keys, returns everybody back to normal etc.). But seeing Zazi at end of the chapter was totally unexpected for me. No wonder this manga still remains in my top ten.
Oh, and Negi's expression was priceless ^_^
