Creamate Comm

Creamate Comm (which is probably a derivation from Creamate Communication) is a feature that was implemented with the update to Ver.2.1.0 on 23 April 2020. This feature is only available for series that also have their Crea Craft implemented to the game. To use Creamate Comm, you need two things: a 5* character of the series that have Crea Craft unlocked and Comm Cards, an item that was implemented just for this feature.

As the name implies, the Creamate Comm revolves about communicating with your Creamates, meaning your characters. The characters have some personal requests for you, and by clearing these requests, you get to see little sequences revolving around the respective character. These little sequences will be listed in the Rewatch Stories section of the Library, just like quests.

General Information
Each character has a total of 5 requests, which need to be cleared consecutively. While the cost of 1 Comm Card remains the same for all 5 requests, the task you need to fulfill in each request differs, as does the reward.

The following table lists all tasks and rewards for each of the 5 requests:

How to do Creacraft Comm
Once you have at least 1 Comm Card and at least one of your 5* characters has some requests that are yet to be finished (which is very likely since simply possessing a 5* character suffices for Request No.1), you will get a notification on the Main Menu that Creacraft Comm is available. Via the main menu, you can enter a Series Building by tapping on any series in the List of Series (the button which is labeled Crea Craft here).

Once you have entered the Series Building, you will find two buttons in the lower right corner. The lower one is for Crea Craft, and the upper one is for Creamate Comm. Tapping on this button will open a list of all characters that have a 5* card implemented into the game, and tapping on any of these characters will show a list of all 5* cards of this character. (If there are some characters or cards you don't have in your character pool, the respective button will be locked.)

Once you have tapped on the card of the 5* character you want to do Creamate Comm, a list of all requests up to now will be displayed. Tapping on the one at the top will lead you to a confirmation screen. Here you can see the task you need to fulfill as well as the reward (for details, see above). You also see the number of Comm Cards, as you will need to pay one upon accepting the request.

Once you accepted a request, you simply need to fulfill the task and report back, similar to Crea Craft. This process needs to be repeated to proceed with the requests.

Remarks

 * As of now (24 April 2020), the notification about available Creamate Comm requests won't disappear unless you a) accepted all available requests (which is not recommended as this is a waste of Comm Cards) or b) have run out of Comm Cards.
 * The only means to obtain Comm Cards is via the Trade Shop; one Comm Card costs one Craft Medal, which is only attainable via Crea Craft. You can only get up to 10 Comm Cards every month, so they are a very limited item.
 * While the character posters are available to anyone who possesses the respective 5* characters, the User Titles require you to have Awakening Level 1 or 5. There might be players who will never be able to obtain these Titles.
 * As just described, Comm Cards are a highly limited item, so you should choose wisely on whose character's Creamate Comm you want to clear. The User Titles might be one factor to take into accounts: As you can only set 1 User Title, you might try to get the User Title you want to have the most. The character posters are only lucrative if you like to re-arrange your Kirara Room. The third and last thing to take into acount is the little communication with the characters. You might want to read these sequences from your most liked characters.
 * As Etoilium are a rare item, obtaining them as the reward for clearing Request No.4 is highly recommended. Speaking of efficiency, clearing Request No.4 costs even less Craft Medals than Etoilium Shards in the Trade Shop. But keep in mind that just like the User Titles, the etoiliums as well require your characters to be at a high Awakening Level.
