Ok, then here we go...

High School DxD 01-02
"The story follows Issei Hyodo, a dim-witted, lecherous second-year high school student who is killed by a girl on his first date ever. Issei is reincarnated as a devil, and from that day forward, he serves as an underling of Riasu, a high-level devil who is also the prettiest girl on Issei's campus."

Spicy red demons.

This looks like okazu, aka side-dish, aka for-fapping anime, but I watched two episodes and I've yet to get a boner, so I don't know. Maybe it's not my kind of taste.
As for the plot, it feels too much like an in-your-face plot. I would have favored a more subtle flavor for my side-dish. But hey, to each its own.
The animation is ok, but it pales compared to the amazing quality of the excellent ED. If the whole anime has been done by the artist who did the ED, maybe I would have reconsidered my opinion.
