Welcome to the Forums Geeky Monkey-san! :) It's lovely to meet you! :D I recommend making an introduction thread where everyone else can get to know you better. :) A monkey and a geeky is some rare breed. Where did ya come from?>_
if you don't mind "long running" manga, or manga that hasn't finished yet then try:
Boku no Hero Academia
The Seven Deadly Sins(Nanatsu no Taizai)
One piece
Katekyo Hitman Reborn
Those are a few i enjoy
