Starting on February 7th and until Sunday 9th, Kiseki journals will be granted a new power. Similar to the CCS anime's 'Create' card, things people write in their journals will be able to materialize. Just like this card, creations will fade fairly quickly once they're created, unless someone keeps writing about them.
There's another catch - at least one character (in this case Sakura Kinomoto herself) will write to ask to meet her friends. Ideally more people will attempt something similar, thus leading to the 4th wall event.
