name: The 4th
notes: 'Ryutaro and Kosuke, having started music production around the same time (winning
  a musicianship in BEMANI to appear in beatmania 4th Style ) had always had a strong
  collaboration, even at a friend level.

  kors k usually handle hard style beats while Ryu☆ used a happy style. This eventually
  brought them to mix their work.

  Early collaboration between can be first seen in the album ''teranoid underground
  edition'' under a song where they showdown "Pumpin'' Rabbit Express", although they
  were referred to as "Ryu☆ vs teranoid".

  The name "The 4th" is likely derived from starting their careers in beatmania''s
  4th Style.'
