Utsusemi ni Akari
This story is somehow very primal: studying the target, testing bait and taking note of the different reactions, trying out another bait... Is he aware yet, that he's being hunted? Preyed upon? Toyed with? And his instincts are already telling him to keep away yet he stubbornly returns to the same habits and places ^^ Just lay down in the trap already and decorate yourself with parsley while you're at it :D
