Attempt to draw SERIOUS Kaiji fanart though it probably still has some comedic value to it (perhaps the same can be said about the actual show xxx)

That is not meant to be some random anonymous admirer forcing herself on Kaiji; remember in episode 13, that metaphor of pale, slender hands gracefully cupping a heart before forcefully squeezing? It reminds me of Akira Kurosawa's "The Blizzard" film sequence, in which a beautiful snow demon sweetly tells doomed-to-death mountain climbers how warm the ice is. That inspired me to give those hands in Kaiji a face; it turned out reminiscent of Leiji Matsumoto's style. The heart thing is tacky but oh well.
Episode 13 is one of my favorite episodes, particularly the part with Kaiji's monologue.
