Konosuba: But Chris is here too

AU. Chris joins Kazuma's party after the cabbage quest, thanks to a game of rock-paper-scissors. How will having a sensible girl affect the story? Surprisingly, a lot. Also includes Kazuma shipping, none of the Devil King Generals dying, references, ghost girls, snow sprites, demon maids, everyone's favorite Crimson Demon cutie, and BITES ZA DUSTO.
