Hitorijime My Hero, Volume 5 (Hitorijime My Hero #19.5-24)

Masahiro Setagawa doesn’t believe in heroes, but wishes he could: He’s found himself in a gang of small-time street bullies who use him to run errands. But when high school teacher (and scourge of the streets) Kousuke Ohshiba comes to his rescue, he finds he may need to start believing after all... and as their relationship deepens, he realizes a hero might be just what he was looking for this whole time.
