Review of High School DxD Hero

So it was a good while until we got DxD Hero, It had been three years and we had been waiting a good while. So Issei saved Rias and now everyone was on their way to a trip in Kyoto except Rias, Akeno, Gaspar and Koneko. You'd think they'd have a blast, school trip, onsen fun. Trials of courage and all that? Hah, well hello there Red Dragon Emperor or do you mean 'Grabbin Dragon'? Issei gets into more **** and eventually falls out with Rias. Because Issei just can't seem to bring himself to call her by her name and keeps calling her President. Baka!
