Everyone knows Issei is going to become crazy powerful in the future. But we can't leave the other Longinus possessors out. While they are not as abnormal as Issei they are still abnormal. So we will see them reach godly levels like Issei. And I'm not saying that Issei isn't going to get stronger, but even with the power of Ophis and Great Red, he isn't going to leave the other guys in the dust. They are as strong as Issei at the moment. I could see all the Longinus possessors coming together to defeat Trihexa in the future. I know that Issei is the MC, but he shouldn't be the only one getting stronger. Issei's remade body put him on equal ground with Vali's immense demonic power and natural talent. All Issei needs to do is train and grow into his power. We just got DxD, do we need another instant power-up for Issei?
