xxxHolic/Discworld, take 7

One final epilogue to conclude the xxxHolic/Discworld crossover series. (Pending any further unexpected bursts of inspiration, anyway. It feels pretty final though, and that's good enough for me at this stage.)

Title: Of Heroes and Sidekicks (aka, the one that is all rusalkaz’s fault)
Summary: In which the owner of the luggage turns out to have more in common with Watanuki than either had realised.
Spoilers: None, though, y'know, you might want to read the other parts first

Previous parts:
Part 1: Just Another Tuesday
Part 2: Binky
Part 3: A Death in the Family
Epilogue 1: The Luggage
Cripple Mr Onion (not a chronological part of the series, but part of the same crossover)

( 'Do you get a lot of monsters around here?' )
