I think that cliches can be done well if you're willing to have fun with them and not go down the same safe road everyone takes.

"My family was tragically killed, and their souls were infused in a katana... but that seemed kind of morbid, so I attacked bristles to the scabbard and use it as a broom now. Also I try to spread happiness, because being a total edgelord all the time makes no sense. My family is always with me. <3"

"An angel told me a prophecy. One that clearly stated I would save the world... But since it's prophecy, why bother working towards a goal that's essentially going to wind up in my lap anyway? I think I'll be lazy and procrastinate instead. Not like that angel was lying to me or anything!"
