Seems like he has a bit of a brother complex going on O_o. Anyways, an episode focused mostly on Ren, good thing he's turning out to be like Kazuma (which is always a good thing). Haha and I laughed hearing Kazuma's evil laughter after wanting to destroy the Earth User family. This anime kinda reminds me of Avatar the Airbender (though controllng elements is a really common theme).
