Yama no Susume series is heartwarming, third season little more focused on friendship than on climbing mountains... in my opinion, this is very nice padding, making more sense of the relationships between the five girls.
Just lovely and after watching third season, I had to backtrace to previous seasons and enhance my score. This season just completes what was missing in previous ones.
Can't wait for next season ("See you again!")! Fans of previous seasons will love this one as well, and as for others who got here by chance, I recommend to start from season one.
