Also I like to thank you now I relise Ichiei Ishibumi might not me hiding some I thought Vol. 20 might of added a sub plot that could change Issei's origins. But his bad logic about the different between dargon and devil since their desgin was inspired by the same thing Bat wings. since devil and dragon wings have the same orgins the idea you could master one and not the other seems to lack logic. So that lack of logic made me question the possible of a sub plot.
