This manga is pretty friggin' awesome.
It takes place in a world where humanity is ran over by titans which resemble genderless humans ranging from 3-15m tall. Humanity decided to encase themselves inside a rampart with 50m high walls with a rail system to move cannons around to fight the titans. For over a 100 years they have 'lived peacefully' until one day an unforeseen event occurs.
