How to obtain:
- Lucca's default weapon.
A gun whose bullets are propelled by air.
It is referenced as the Zonker-38 in Guardia Castle. In the original Japanese, it was a Disposable Explosion Blast Pistol.
The Air Gun probably alludes to air rifles or BB guns, which would explain its place at the bottom of Lucca's weapon ladder.
