The second arc of this story is focused narrowly on the aftermath of the first arc and Yurika. 

Yurika is a rare type in VNs these days... a sexy adult woman who isn't another man's wife or widow (yes, I went there).  She is a member of the 'Virgin of Chains', the more 'peaceful' of the two mafia groups dominating the area.  She is the protagonist's friend, occasional partner, drinking buddy, and sex friend. 

She has a somewhat nihilistic attitude toward life and an absolute love of teasing the protagonist... and anyone else who leaves an opening for her.  Like all the heroines in this VN, she is fairly attractive, though she is somewhat overly pessimistic at times.  Of course, she has very good reason for this, but I won't spoil that for you.

In the aftermath of the second arc, I took pleasure in reading her path, which was a bit more icha-love focused than Kazuha's was at first.  It does fall into the classic 'it was nice up to this point precisely to outline the drama' area, so the drama near the end of the path is pretty satisfying, and I honestly enjoyed the atmosphere of the path as a whole.  I will say that I preferred Kazuha's path and I thought they could have gone a bit farther with her personal story (I thought that they glossed over a bit too much detail when it came to her eye).
