I have been reading Stan Sakai’s Usagi Yojimbo since I was a kid. Throughout his journeys Usagi has encounters with all sorts of Yokai (spirits and demons from Japanese folklore). These encounters are treated with the same vivid attentions as any of Usagi’s more historically aligned experiences. Forces that are unexplained or unseen can have great importance for the relation of imagination and reality. In the Usagi books the lack of separation between demon presence and reality has always been inspiring and reassuring to me.  The second drawing is my version of a Kappa.
