Besides stories and Anki, is there any other way to remember Kanji that you can't remember?

Well there are all the others methods. They're not as good imo, but ultimately it depends on your own style of learning. Various mnemotechnics (using words (while Heisig uses images), loci...), rote memorization, contextual association with words (Tae Kim mentions it on his blog), and probably others I'm not aware of.
