Anime Like High School DxD
High School of the Dead
The amount of sexual content in High School of the Dead is only outweighed by the number of times the laws of physics are defied. Plenty of scenes in the show will force you to suspend your disbelief. That being said, the show does provide an entertaining look at how a group of high school students might survive the zombie apocalypse without the aide of adults.
The harem elements are minimalistic in this anime like High School DxD, as most of the women who express an interest in Takashi, the main character, eventually shift their emotions to other men in the group. Also, High School of the Dead gets plenty bloody at times too. Unlike High School DxD’s cartoon levels of violence, High School of the Dead features plenty of blood and some instances of gore.
