Atelier Totori: The Adventurer of Arland

- Watch the event with Melvia about Ceci as soon as you visit one wild area
- Soon after you will be able to watch another scene with Melvia; Mel's Friendship Level needs to be at least "50".
- As soon as the second half of Year 2 starts, you can watch a scene when talking with Melvia in Gerhard's Bar; Mel's Friendship Level needs to be at least "60".
- Talk to Ceci then so she can join you adventuring; Melvia needs to be in your team so Ceci will join both of you.
- Wait at least one month and invite Ceci again; this time with Mel as well; 2 days will pass after the adventure.
___________________

In case you want one of the character endings or the True Ending, or at least the "Ambushed" trophy continue this way:

- One month after you can invite Ceci again while Mel is in your team; during the following scenes you get the trophy. You will also have to fight 3 Scarlets with Totori. But you don't need to defeat them. However, you can do that as long as your Level is high enough (recommended: 35+), have a good equipment with Totori and some strong Bombs as well as the ability to use them automatically once your Hit Points get low.
