How to Legally Get Your Favorite Character to Wish You a Happy Birthday

Project Sekai doesn't have a feature to celebrate the user's birthday... Every year around this time, there are no special congratulatory voice lines, and while there are gachas, there aren't any specifically for birthdays, which feels a bit empty... Some other games have features to celebrate the user's birthday, but while Project Sekai has a function to celebrate characters' birthdays, it lacks a function to be celebrated. I hope they implement something like that from the 6th anniversary onwards... So, by searching for voice lines other than "Happy Birthday, [Name]!" in the 'Lines' section, you can legally get birthday wishes from your favorite character! ※The first image is directed at Kohane.
