Let's get this list started with Lilim Kiss! This is another shounen manga revolving around Saiki Takaya, your ordinary guy. Even though he is ordinary, he keeps being misunderstood. His life turns upside down one day when he finds a flask containing a succubus called Lilim. Lilim is a very attractive girl, who gains energy by kissing guys. After kissing Takaya, she claims that his energy is the tastiest she's ever tried. So what happens when Lilim starts living at Takaya's, as his girlfriend?

Karin and Lilim Kiss share basically the same genre and premises. Both these stories revolve around a boy who finds himself involved with a troublemaker monster, who happens to be cute, or sexy. These two boys – Kenta and Takaya – are at the mercy of Karin and Lilim, and that's what starts the funniest gags in both cases. It's true that Lilim Kiss wields ecchi elements and Karin doesn't, but we can guarantee that you'll get the same feelings while reading it!

Now let's switch to manhwa, and talk about Orange Marmalade! This is set in a time when vampires are forced to stay hidden because treated as outcasts. Ma Ri Baek is our protagonist; this girl is a vampire who faced a lot of hardships because of her being a vampire. Her life experiences left her unable to believe in love or friendship, but life puts on her road Jae Min Jung, whose blood has a sweet scent. As Jae Min starts to fall in love with her, Ma Ri is forced to cope with her feelings after their fated meeting...

Orange Marmalade can be considered as the shoujo version of Karin, as it is sweeter and more focused on the romance part. Aside from this, though, Karin and Orange Marmalade share a cute protagonist who is a vampire trying to live her life as a normal human being. Both the couples in these stories have to face a lot of hardships, caused by misunderstandings and the trouble to overcome the different species barrier. If you wish to read a tenderer version of Karin, Orange Marmalade is what you're searching for!

Asahi Kuromine is your high school boy, who is unable to lie. While this may be a virtue on one side, it can turn into a defect on the other. In fact, Kuromine happens to discover something very shocking. The girl he has a crush on, Youko Shiragami, is actually a vampire. Kuromine being a boy unable to lie, will he manage to keep his crush's secret safe? Join him to discover what happens!

Karin and Jitsu wa Watashi wa are both shounen manga, containing comedy parts and supernatural elements. Karin and Youko are the female protagonists and are both vampires. Their relationship with the male counterpart becomes a pivotal focus in the plot. Actually, Karin contains a darker part later on in the story, while Jitsu wa Watashi wa sticks to the lighthearted atmosphere until the very end. That's why, if you wish to read an even softer version of Karin, Jitsu wa Watashi wa is a perfect choice!

Let's go on with a story set in Hokkaido. Our protagonists are Chise, who is a bashful girl, and Shuji, an ever-nervous boy. They are high school seniors in a small town, and their life and their relationship are turned upside down after a bombing attack by an unknown country, resulting in the destruction of the city of Sapporo. The bombers then are destroyed by something, and that something is Chise: Shuji discovers that she is a cyborg engineered by the Japanese Self Defense Force! But what about their love story, now?

Karin and SaiKano may differ in the plot, but they give the same vibes. SaiKano is more adult-oriented, as it is a seinen, and yet it shares with Karin some interesting traits. These two stories have a very good balance of humor, drama, and conflict; at the same time, there's still room for romantic developments between the two main protagonists. While Karin and Chise have supernatural characteristics, they're both fragile and just want to live a normal life, as normal human beings. If you enjoyed Karin, you're bound to enjoy SaiKano all the same. Consider it as the seinen version of Karin!

Let's head toward the end of this list with another popular manga! Servamp revolves around a high school boy, Mahiru Shirota, that has been left without parents. Life is difficult for an orphan who lives alone, but Mahiru's life changes when he finds a black cat on the road and decides to keep it – naming him Kuro. Kuro is no ordinary cat, though: he is a servamp, a servant vampire. That's how Mahiru ends up in an ancient conflict between vampires and humans!

Karin and Servamp share a protagonist who is a vampire, coming in contact with human beings. While Karin is a shounen, Servamp is a josei manga that multishippers out there will find very interesting as there are a lot of BL possibilities among the huge range of bishounen in the story. Kenta and Mahiru find themselves involved with vampires, in spite of everything, and their lives will become a funny mess. These two manga are able to mix the right amount of gags, dramatic moments and supernatural perfectly. So if you wish to read a josei version of Karin, full of cute bishies, Servamp is a must-read!

And now, let's end this list with Fushigi no Maria-kun! Abe Maria is your ordinary high school student, leading a normal life. He is the last pure blood vampire in the world and Tokuko Nanami's childhood friend. Tokuko has been encouraging Maria to become part of human society for ten years now and acts as his guardian. What happens, though, when friendship turns into love?

Karin and Fushigi no Maria-kun are both stories involving a vampire who interacts with an accepting human being – Kenta and Tokuko. Both these stories show the developments of their relationship, through difficulties, hardships, and misunderstandings created by the difference in the species. You can consider Fushigi no Maria-kun as a shorter version of Karin, therefore as a more lighthearted manga, with the same good vibes you enjoyed while reading Karin! So go catch it up, it won't fail you!
