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?
You fight every day, 
you're bound to get stronger.
عندما تقاتل كلّ يوم، تصبح أقوى
Man kämpft jeden Tag,
also wird man stärker.
Si practicas a diario,
te haces más fuerte y ya.
Si practicas cada día,
te haces más fuerte y ya.
À force de se battre,
on devient plus fort, point.
Se combatti ogni giorno, diventerai più forte.
Se você lutar todos os dias,
você vai ficando forte. É óbvio.
Просто если сражаться каждый день,
то станешь сильнее.
