Today I'm recommending Spirit Circle by Mizukami Satoshi.
This right here! This right here is one of my favorite manga made by an absolutely brilliant mangaka. From the creator of Hoshi no Samidare, comes Spirit Circle. Basically the best way I can describe this while keeping it short is, is that the two main characters (only one of them pictured) are thoroughly connected via fate and many past lives, making them eternal enemies, all due to a cursed birthmark hiding behind that bandage of his.
This series is amazing, if you've read Hoshi no Samidare (Lucifer and the Biscuit Hammer) you'll know what kinda story telling Mizukami Satoshi can do. This is honestly an A+ series and one of my longstanding favs, and one I constantly recommend to friends whenever they ask me for a recommendation.
