To trigger this extra event, have the following requirements fulfilled.

• Alicia and Lavian must still be in your party, as well as Agrias and Mustadio.
• You must have at least 500,000 funds available to you.
• You must be at the beginning of the chapter four. It may work after this, but that’s the minimum advancement you have to have had achieved through the game.

If all of the above is true for you, head to a town where you can advance to another town without triggering a random encounter. Go back and forth between the two locations you’ve chosen until the date is Cancer 1, which is Agrias’ birthday. If you’re in a town on Cancer 1, a triggered event will occur where Mustadio will give Agrias a present. It’s called the Tynar Rouge, and it’s a powerful item indeed!
