Happy Photo

Happy Photo
Happy Photos (ハピフォト or hapifoto), are cards that show the "memories" of Tomoeda. You can collect them through gacha pulls or through events. They can be strengthened with the use of Kero Coins. Collecting duplicates of the same Happy Photos allows you to further strengthen it, and collect more items.

Happy Photo Set
You can select four photos of your choice in the happy set to activate their boosts. The strength of these boosts depends on the level and rarity of your selected photos. Once you activate the Photo Set, the cumulative effects of the photos will last for ten minutes. During this period, you will be able to see white feathers fluttering down over Tomoeda.

After these ten minutes, there will be a cooldown period of another ten minutes, during which you will be unable to change your selected photos. You can however, use a feather of time during this period to extend the effects of the set for another ten minutes.

Happy Photo Album
The photo album maintains a record of all the photos you have collected till date. When you select a specific photo, you will be able to see its level, the gameplay mechanic it boosts, how much it boosts said mechanic, and you can read its unique story, in the case of a three star photo.

The album can be set so that it filters out photos based on rarity, or the arc to which they pertain to.

One Star
One star Happy Photos are screen shots from the the anime series (both the original and the recent clear card arc). They are marked with a silver border.

Two Star
Two star Happy Photos depict various canon-compliant scenes, or if they are obtained via events, act as visuals for the event stories. Obtaining duplicates of these will result in additional sparkles being added to the image. They are marked with a gold border.

Three Star
Three star Happy Photos are the only photos where new stories relevant to the characters in the photo can be unlocked. The first part of the story can be unlocked by clearing a photo challenge after obtaining the specific photo while the second part of the story can only be read after obtaining a duplicate of the same. Once a duplicate is obtained, the photo will change and a new photo challenge will be unlocked. Clearing this challenge will unlock the second part of the story. These photos are marked with a multicoloured border.
