maid is strong, a fighter (i think she is a gangster or samurai, she has a wooden stick weapon and a bike i think) and her master is a boy... thats all i remember please help

Could it be Kimi wa Boku no Toriko nare?

Tokyo Crazy Paradise, maybe? She's not really maid, actually... But it sounds similar... >.>

not those.. i remember the maid clothes were like traditional samurai clothes like wrapping a cloth on her chest or something

perhaps it is Omamori Himari. ok didnt see the bike thing

Kimi wa Boku no Toriko nare
im not really sure,but you can try that >.>
