Lucy and Saza leave on good terms, and they instantly find their replacement in...
The Glutton Gyaru!
I think that resolution was handled very nicely. Mature, understanding, no hard feelings or resentments. I did like that Lucy's tsun made way for her dere at the end there when Kachua affirmed their friendly rivalry and mutual efforts to gain strength.
I hope Saza gets his head in gear and properly confesses to Lucy eventually, too.
Anyway great stuff as always. Thanks for your work on this series.
