What have the Idaten been doing in the eight hundred years without any demons to fight? Where do they come from? What is their true nature? And what are they going to do when Dr. Obami plots their defeat?
an Idaten who shirked his training 
in order to learn in the human world
إيداتين تهرّب من تدريبه ليتعلّم في عالم البشر
war ein Idaten, der das Kampftraining aussetzte,
um etwas über die Welt der Menschen zu lernen,
considérait un Idaten ayant déserté
pour étudier avec les humains
un Idaten che ha abbandonato il suo allenamento
per conoscere il mondo umano
um Idaten que abandona o treino e
começa a estudar na sociedade humana
идатэн, который забросил тренировки
и ушёл в человеческий мир учиться,
