Praise the Sun!
Yuu is a high school kid who doesn't really fit anywhere. To find a place he can belong, be accepted, he will do anything. However one thing leads to another and he is forced to fight to keep his place, his holyland.
Though im not too fond of the artist's style (eyes kinda creep me out for some reason though not as much as Kishin Taisen's eyes) the manga reminds me of Worst alot however this manga focuses more on the combat rather then the gang rivalry aspect of the story (or in worst's case school rivalry)
What i like most is how the author elaborates more on the ways the traditional fighting styles shown and used in the manga (ala boxing, judo, karate, etc) can be used effectively on the streets (even going so far as explaining how the techniques were effective and what their purpose in the battle was)
Its definitely a good read so i'd check it out
