name: Hello, Happy World!
name_real: ハロー、ハッピーワールド!
notes: 'Hello, Happy World! is a band created in the multimedia franchise "BanG Dream!".
  Unlike other groups in the franchise, the unit does not perform live, although some
  members have appeared live with the backing band "the Third" (which would later
  be renamed RAISE A SUILEN).

  The members are:

  Kokoro Tsurumaki, Vocals (CV. Miku Ito)

  Kaoru Seta, Guitar (CV. Azusa Tadokoro)

  Hagumi Kitazawa, Bass (CV. Yuuri Yoshida)

  Kanon Matsubara, Drums (CV. Moe Toyota)

  Michelle (alias of Misaki Okusawa), DJ (CV. Tomoyo Kurosawa)

  The creation of the band and announcement of Miku Ito''s involvement occured on
  December 7, 2016. The other members were revealed at a live event on February 24,
  2017.

  Hello, Happy World!, often shorted to HaroHapi, officially became the fourth band
  in the franchise with their debut single release in August 2017.'
