Petra has the same schedule every day of the week. Occasionally she can also be seen walking around the entrance to the Cemetery.

Here’s her full schedule:

19:00 Arrives at Martha’s Bakery and browses the goods
20:00 Leaves Martha’s Bakery and sits on a bench in Central Plaza

Gift Guide

It’s no surprise that when it comes to gifting Petra, your best bet is assembled Relics.

You can find pieces of these relics in the Abandoned Ruins, and then Assemble them with a Recovery Machine.

TIP: You can get a Recovery Machine for your yard as a reward for donating to the Museum. It will not use Data Disks to make the relics.

TIP #2: Unlick most of the other characters in MTaP, Petra does not like gems such as Ruby, Sapphire, or Topaz.

Petra is fully dedicated to her research and is determined to make the world a better place through her work. This means that all her quests have something to do with helping her in her research.

As head of the Research Center, you will have to talk to Petra about a lot of your missions. Most of those missions will not give you Friendship Points with Petra.

But you can gain Friendship Points and Rewards from Petra by completing the following missions:
