I think some of you are obsessed with "Vritra is the weakest in terms of raw power." Do any of you think Kiba is weak because he lacks in terms of raw power? You guys act like Issei is the only one that can improve and train. Some of you spend all this time hyping Issei while putting down the other characters just because they aren't as strong as these guys that are abnormally overpowered. You think Saji doesn't train. You think he's not strong or can't become Satan-class because he's very lacking in the raw power department compared to Issei? Among the Dragon Kings, Vritra had the least raw power among them. I would rephrase it that way. Remember that Dragon Kings are very strong among other dragons.
