I am an endless well of ideas, perhaps the MC is an elf adventurer who has to gather a party together to save his kingdom but he ends up getting party members with weird quirks that end up leading them to get killed so he has to start over, until he teams up with a cat demon with a habit of falling down stairs and NOT landing on his feet, a magical witch boy who can only curse people named Edwin, a fairy guy who is afraid of other fairies and a troubled fellow elf mage who never casts a single spell but somehow knows everything about a given situation due to secretly being an assassin that must always find his target, or his magic will never return.
