A Traveler who is Helpful to the City

This time we're going hunting. Terranoa is in the sky, so it's safer than any other city, but the situation at Mastcot is totally different. I have designated Grando to manage the place, but she is barely handling the places near the Puertoal. So whenever a traveler like you comes to the city, I lessen her workload by asking travelers to destroy one or two Plefters at least. Destroy forty Plefters at Mastcot and bring back Confirmation from Supervisor Grando. Then I'll believe in your abilities.

I'll put it simply. Destroy forty Plefters at Mastcot and bring back Confirmation from Supervisor Grando.

No wonder you were destroying all those monsters. You were sent by the captain? Travelers like you are always coming and going. You want the Confirmation, right? Come here.
