March 6 is designated as "Otouto Day" or Younger Brothers' Day in Japan to celebrate all the annoying little brothers that bring much frustration and happiness to their older siblings. (Don't worry, there are days for other siblings too!) If you're an otouto, this is your day to go prank on your onee-san and onii-san! We've put together a collection of some of the most iconic anime younger brothers for all the otoutos out there!
