So I've finally caught up with YamaNade and it sure took me long to read all these chapters...
This chapter was really cute. I love this "couple"! ♥
Sadly there's a lot of what HealthHazard had said, finding medieval weapons or competing in something. But if you compare the earlier chapters with the recent chapters you see Sunako's "normal" body more often instead of the chibi form so one can definitely see it as her developing her self-confidence in some way or another. Also since she and Kyouhei seems to get along much better now we can just hope for some plot and finally the end. I'm hoping this won't continue until like... chapter 150+. ):
This has been published since 2000 so the author should round it up soon...
