Harajuku

Harajuku is a ruined city overrun by Horsemen and vampires in Tokyo between Shibuya and Shinjuku. Shinoa Squad performs its first vampire extermination mission here.

Details
Harajuku contains Omotesandō Station, which has been infested with vampires. They keep livestock here. Although they do not keep the livestock imprisoned or trapped in the station, the livestock does not run away. Horsemen in Harajuku will attack any humans they come across, so the livestock require protection from the vampires.

Compared to Sanguinem, more of the livestock appears gaunt, tired, and dirty. They appear sitting in the station rather than running around or playing.

Shinoa Squad performs its first vampire extermination mission here and successfully exterminate all nine vampires stationed here. After this, one of the freed human livestock yells at them for killing the vampires and removing their only protection against the Horsemen. Since the cities of the Japanese Imperial Demon Army have population restrictions, it is difficult for livestock to enter Shibuya or Shinjuku, leaving them with no choice but to be killed by Horsemen or to rely on the vampires. After Yūichirō Hyakuya calms him down, Shinoa Hiragi informs them that Shibuya should now have enough expansion to accommodate all of the livestock from Omotesandō Station.
 * "How could you do this to us?! Why did you have to kill those vampires?! Now that they're dead, what'll happen to us?! To our children?! You Demon Army people won't even let us into Shibuya or Shinjuku or anywhere else, thanks to your population regulations! How are we going to live out here?! Who's going to protect us from all the monsters?! You damned elites, living in your safe little garden behind those magic walls... Do you think you're heroes?!" - Livestock, Chapter 9, "First Extermination"Episode 8 - Screenshot 1.png

Shinjuku Arc
Shinoa Squad goes on its first vampire extermination mission here. They see a human child being used as bait. When a Horseman chases after her, Yūichirō Hyakuya disobeys orders and steps in to save her. Vampires ambush him, but his squad steps in to protect him. They take the child to a Shibuya Observation Post, and she gives them information.

The next day, they invade Omotesandō Station, killing vampires as they go. Although their informant told them there were only seven vampires, there are actually nine vampires in wait. Shinoa Squad exterminates them and frees the humans from vampire control. Without the vampires' protection, the humans are completely vulnerable to Horsemen, so Shinoa tells them that Shibuya should have undergone enough expansion to accommodate them.
