This manga definitely holds the same feel as the first part, but it loses a lot of the charm, especially in the second half. In the earlier phases you get classic comedy and slice of life bits that made part 1 so good, but then it later becomes but a long fight(which wasn't even that bad in my opinion, but it definitely made everything feel tons more bland.)
However, I think the biggest gripe I have is the actually absurd amounts of rape scaring and then adding one account of rape itself. There are 4 attempts(including the one which was successful) in this 86 chapter manga, averaging 1 attempt per 21 chapters. There are about 5 noteworthy women in this entire part and 3 of them manage to be threatened with rape, with the other two being Misaki and a random assassin. At some point it becomes weird even to those who don't find it disturbing, especially since this manga is an action manga about assassins.
Personally I ended up settling at a 7.5/10, going down from a 9/10 during the move towards the second half the manga.
