Agnus Dei - Lamb of God
Dark Heaven
A story that gives you a look into the lives of victims of homophobia and xenophobia in the fictional town of Van Tescosa. The main characters are a gay biracial couple that face the several obstacles that their messed up society creates for them. Although heavy, it also has its cute moments. Overall, it's a must read. It's amazing and I love the couple.
Shinigami Hime No Saikon
It's a good light read.
Killing Stalking
Although not really my taste, 4 stars for memorable.
Kuroshitsuji
If you like mystery, horror, or other creepy shit but you don't feel in the mood for something overwhelmingly dark then this is the story for you. This manga has an amazing balance between supernatural mysteries and comedy that make it possible for you to enjoy the story and binge all the chapters.
Enka - Zetsurin Ou to Yokubou Ouji
