These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The following tropes are YMMV (Your Mileage May Vary)
Growing the Beard: While there have been some serious moments in the previous volumes, itís in the fourth volume that shit really hits the fan. There are less funny situations, some on-screen deaths, some serious fights with injuries, and the more dangerous renegades like Tiamat and Rendo appear/return.
