3-gatsu no Lion meets Bump of Chicken  

March comes in like a lion meets Bump of Chicken, Lion of March meets Bump of Chicken

A CGI music video of Sangatsu no Lion set to Bump of Chickens "Fighter" single. The website states that the collaboration started because the mangaka Umino Chika is a fan of Bump of Chicken and the members of Bump of Chicken are fans of Sangatsu no Lion. A special edition of the mangas 10th compiled volume shipped on November 28 with this single.(Source: ANN)
