Bomba!

Tetsu is a seemingly normal student whose passionate love for his teacher turns violent in the most unexpected of ways when another suitor attempts to stand between them. Haunted by his family’s past, Tetsu must learn to navigate his desire and quell his rage if he hopes to find peace and solace in his relationships with others. Osamu Tezuka’s masterful artwork and irrepressibly creative page layouts reach a feverish peak in depicting the manifestation of the tortured youth’s explosive angst.
