Volume 1 is the 1st volume of Tenjou Tenge manga series.
Soichiro Nagi and Bob Makihara have always been the meanest street brawlers around. When they enter Todo High they plan on carving out a reputation as the strongest fighters in their new school—easier said than done in a place that's dedicated to training its students in the art of combat! After realizing they're the new fish swimming in a tank full of sharks, Soichiro and Bob enter the Juken fight club as rookie members. However, the Executive Council—the archrival of the Juken Club—soon launches a surprise attack. Soichiro and Bob have a chance to show their stuff, as long as they don't get curb-kicked in the process!
