Sarai-ya Goyou

House of Five leaves   さらい屋 五葉 

Akitsu Masanosuke is a timid ronin on his way to Edo from the countryside when he accidentally encounters a playboy named Yaichi, who asks him to be his bodyguard. But it turns out that Yaichi is actually the leader of a group of bandits called the "Five Leaves," and he's hoping that Masanosuke will join them. Masanosuke is reluctant to help them, but as he grows closer to his eccentric new companions, he learns to relate to them and grow as a person in the process.
