*zzzing**twitch*I'm gonna *beep* that half-assed four-eye youkai later.She tosses up her finger, like a unicorn flaunts its horn! (Kou)She thrusts the other hand out as if raising a toast!As expected, two horns can't compare to a unicorn! And no loli can beat a pair of buxom breasts. (Kou) After NHK broadcast 赤鬼と青鬼のタンゴ (Tango of the Red and Blue Oni, song written by Katou Naoyasu) in 1977, it became a popular concept that blue oni and red oni have a different number of horns. Also, since that anime, they have been frequently portrayed with different builds. This concept has no relation with traditional Japanese folklore, however, where blue oni and red oni have no difference except skin color.
