These two anime have a similar outward appearance to them: both feature nature and bugs as sort of an underlying theme behind the 'plot', both have big-eyed teenagers with mixed feelings towards each other and both have gory scenes. If you enjoy looking at bugs and blood, then this is your type of show.
