I like this anime because of Kazuma's random noises he makes when other people are talking. The scene at 1:55 is what I mean. After she throws the clothes in his face while yelling you can hear him casually say "that hurt" (although he actually says 痛い) Also when the girls call him Kazuma sometimes he casually responds with "I'm kazuma" (though he actually just says かずまだよ usually)
