Sorry, it seems the wording in the change log was misleading.
Regarding the line:
> Added the ability to use hoses from the start when selecting characters in selection mode.
Hose items are now available from the start only when selecting characters from the “select from VRM file” option. (This change was made because it was cumbersome to play the game each time when experimenting with multiple VRM files.)
For the two default characters, items cannot be obtained unless you progress through the game normally.
