This series is a change for me. I personally like supernatual, fantasy type series, yet this manga couldn't be any more realistic. Evil Heart revolves around a very aggressive 12 year old boy named Umeo, his older sisters struggle to look after him alone and combat his behaviour, and stigma within the society. Umeo comes across a very different martial art, taught by a Canadian school teacher with a very positive outlook on life. Will this teacher take on a student with such negitive intentions? In this manga, we delve into the troubled family history of Umeo's past and discover his reason for wanting to be strong.
