High School DxD. That's like a completely different series, but now that you mentioned it, it seems like High School DxD also pick up a notch, the latest Volume, Volume 16 only has one small fanservice in the beginning, the remainders are all serious plots, introduction of new Ophis, the Leader of Khaos Brigade, the Evil Dragons, etc.
