Yes! Haqua arc finally!
This arc introduces the second Demon member of Keima’s growing harem and also marks the first real change in tone of the story. It also gives a bigger importance to the whole Soul-capturing operation as well with the plot exposition that Haqua gives to Keima.
More importantly though, a real tsundere character! \(o.o)/
Tsundere Saorin is delicious :DDDDDDDDDDDD
