My name is Kasuga. Kasuga became a Z/X user to find the news about Mika Nii-cha... Mika Nii-sama who gave his effort to turn myself from devil back to human. Kasuga's growth has been halted as the effect of turning into devil when Kasuga was 10-years-old, but Kasuga is actually 13-years-old. Since my age is different from the identical-looking Sera-chan, it would be helpful if you could tell us apart. Mask of the Divine Progenitor of Greed? Yes, Kasuga still have it. But since Kasuga's devil personality are sealed on it, Kasuga is having trouble handling it.
