The third brother. Since he is the only one among the sextuplets with common sense he often plays the tsukkomi role, but that doesn't prevent him from joining in on his brothers oddities now and then. He really likes cute girls and idols. His distinguishing feature is his angular mouth and he often dresses in green.
