Angelo Lagusa has seen probably the worst thing that anyone could ever see. You see, his parents and brother were killed right in front of him on a snowy night. Not only that, but he knows who did it: the Vanetti mafia family. Angelo gets rid of his identity and poses as Avilio Bruno. Years later, Bruno received a letter and he meets a man named Nero and befriends him. However this is not because he likes Nero as a person, but rather because Nero is the son of the Vanetti family. 91 Days tells the story of Angelo as he goes from body to body in his revenge.

At first, people might not pick up on it immediately, but both series feature two warring factions that more or less are families, be it related by blood or not, as they go at it. They do have slightly differing motives as the vampires want something and the Jaegers want to eliminate them and Angelo wants to take out the Vanetti family. However the theme of vengeance is always simmering below the surface and there’s plenty of action to keep the viewer entertained.

Inuyasha follows the story of Kagome who one day is dragged down a well. She wakes up to find herself 500 years in the past. She then learns, after being attacked, that a special jewel known as the Shikon jewel, a gemstone containing magical powers, is hidden in her body. Kagome loses it to a demon, but fires and arrow to try and stop the demon, but ends up shattering the jewel. After freeing Inuyasha from his imprisonment, the two set off on a journey to try and find the shards and make the gem whole again lest it fall into the wrong hands.

Inuyasha might seem a bit different, but it actually is quite similar. You have two different factions, both supernatural at that, fighting for control over something. While you know it is the Shikon jewel in Inuyasha, the Vampires in Tenrou: Sirius the Jaeger keep everything shrouded in mystery. Regardless though, the heroes hunt down the villains who hide in the shadows rather than attack outright. Both series are set into the past but naturally one is farther back than the other. Inuyasha and Tenrou: Sirius the Jaeger also both have two brothers who are at odds and will cross swords or weapons if need be.

Technology has made massive steps forward in a nation that looks like it walked out of 1960s Europe. Keith is a genius who works with the police there and is deeply respected for his insight and intellect. However when a strange name pops up during what what should be a routine investigation into a homicide, Keith’s ears perk up. Killer B. That is the name of a strange being that appears to have some sort of deep past connection to Keith. Suddenly things start to grow closer and closer as more are discovered. But is Keith ready for what he will find both wanted and unwanted?

B: The Beginning was brought to us via Netflix in a slew of adaptation announcements for anime last year and was arguably the best one we were given. Here too we have a main character where we are given very little information about, and we have to watch as they not only grow and hunt down criminals and organizations, but also how they are looking into their pasts. Well, we are through their eyes, but still. Both share tragic pasts with Keith’s orphanage and Yuliy’s family, and it’s clear that more is to come as we unravel the mysteries surrounding them.

The government is useless in this story. After a terrorist attack on a nuclear plant completely fool the cops, the government can do nothing and so, the incident fades into obscurity. Until a few months later when a video surfaces online of two boys in masks challenging the police to a game. If they can pass, great; but if not, then bombs will go off randomly around Tokyo. The police scramble to try and figure out where these boys are, but it seems to be futile. That is when Lisa Mishima is accidentally caught up with these boys and has to make a decision for herself...

On the surface, Zankyou may seem different, but it does make a lot of sense when we look under the hood. You have two main characters in Nine and Twelve who are tortured souls wanting vengeance against those who have done them wrong in the past. This is the same for Yuliy and his role within his group. Yuliy wants nothing more than to destroy every single vampire. This is only compounded with his righteous anger. Society may be crumbling around our main characters, but they only have one goal in mind: vengeance.

Everything is normal for Saya Otonashi, a girl living with her adoptive family. She is a cheerful girl who has a strange bout of amnesia and for some reason, she cannot remember what happened over the last year. She shrugs it off though until one day when she is attacked by a creature who wants blood. Saya is saved by a man named Haji who teaches her that her own blood is a special weapon. It is then that she wakes up to her powers and becomes an incredibly powerful fighter. Learning more about who Haji is, Saya’s loved ones meet a horrible fate and Saya swears revenge against those who have done her wrong. With Haji at her side and her incredible power, Saya now chances these terrible monsters.

So we get it. You want more than vengeance and revenge as a plot device, well good news for you! We have more. Both Blood+ and Sirius the Jaeger feature vampires as central plot devices. While one is a lot more shocking (as of this point) both do feature vampires that are more than just “creatures of the night” as they terrorize anyone and everything in their paths and that is either unintentionally or intentionally. While Sirius the Jaeger hasn’t whipped out the tragedy too much, we know that more is around the corner. We just wonder if it will be as much as Blood+ has.

Vampires are on the rise after a strange virus wipes out everyone at when they hit 13. Following this bloody revolution by the creatures of the night, two boys Yuuichirou and Mikaela are taken to an orphanage. They hate being subjugated and try to rebel and escape. Yuuichirou is the sole survivor of this massacre and joins a company that takes out demons. Years later though, Yuuichirou plans his revenge against these vampiric monsters. However, just how dedicated is he to this goal? Are all vampires bad all of the time?

Owari no Seraph is the final show on our list bringing a litany of similarities with Sirius the Jaeger. Both feature a main character who not only watches his brother sacrifice himself to save the main character after their families have been slaughtered, both join factions dedicated to the eradication of vampires as we know it. After thinking their brothers are dead, contact is made with the brother and suddenly the main characters face a moral crisis over what they are doing. Both of course also feature great fight scenes, so look forward to that if you want more action!
