List of temporary and disbanded units
School idol groups typically either disband following the original members' graduations (as with μ's or Sunny Passion), or continue activities with the remaining members (Aqours, Hasunosora Girls' High School Idol Club). However, school idols may also choose to disband their groups prematurely.
In some cases, the groups may be planned as temporary from their conception; more frequently, however, conflict between the group's members is the cause of disbandment.
The following is a list of known temporary and/or disbanded school idol groups:
Love Live! School idol project

Love Live! Sunshine!!
