In deze "romantische komedie, maar soms ook magische schoolverhaal" wordt het leven zoals Arata Kasuga het kent, weggevaagd door een bizar incident genaamd "Instortingsfenomeen", dat wereldwijde verwoesting veroorzaakt en zijn neef Hijiri Kasuga naar de volgende wereld voert. Om het "Instortingsfenomeen" op te lossen en Hijiri terug te brengen, schrijft Arata zich in bij de Koninklijke Biblia Academie. In de school wachten zeven prachtige vrouwelijke magiërs – de Trinity Seven.
Nee, helaas is トリニティセブン nog niet beschikbaar op Netflix in Nederland.
