My favourite part has to be the description of the submission. I read it from the perspective of some chap being overly enthusiastic about, after several years of trying, finally figuring out how to combine their two most favourite things in life. That or someone trying to make an excuse from failing to play chess with Wakasagihime, forgetting that chess pieces float around underwater.
And yes, I too find enjoyment in the pillars being chess kings.
final rating: go fish/10
