At the beginning, you can see Jovy is in the West Ward of Nalbina, lying on the ground and says his hero has gone ...

Now clear all Mob/Mark Hunt mission that were given by the clients/petitioners in Nalbina, which are:
- Atomos ----- by Burrogh ( rank C/III )
- Roblon ----- by Morgen ( rank S/VI )
- Goliath ---- by Barrong ( rank S/VI )
- Deathscythe - by Popol ( rank S/VI )
- Carrot ----- by Zammadria ( rank H/VII )

Once you've done, back to Nalbina and speak to your clients/petitioners for the rewards (you don't need to clear them in once), and Jovy will show up for a scene with each of them, then leaves you a "snort".

After all, find Jovy in the West Ward area which is outside the Aerodrome/ Airship Terminal, he's running across the middle, talk to him for a scene, and you will get Elixir and Knot of Rust from Jovy, as well as became his new hero.
