In "Dragon Ball Z: Buu's Fury," to get past the guard in West City, you need to collect the necessary item called the "West City Pass." This item can be obtained by completing a side quest involving the character called "Boo." Once you have the pass, return to the guard, and you will be able to proceed into West City.
