Another great manga is Loveless. It’s sorta hard to explain, but I’ll do my best. The main charactor is Ritsuka who’s mother abuses. In it, there are things called fighter units and sacrafices. The fighter units battle off against eachother using spells, but the sacrafice is the one that the pain is inflicted on. When the sacrafice is completely restrained, that fighter loses. So, Ritsuka’s brother, Seimei was mysteriously murdered leaving his fighter unit, Soubi, in Ritsukas hands. Now, Ritsuka has to unravel the mystery of Seimei’s death while battling of other fighters.
Sounds like a good manga? Well, my explanations suck. So, be on the lookout for it.
