Let’s Hanami runs from August 24th 05:00 LNST to August 31st 23:59 LNST. Stylists will play regular journey stages to earn Petals throughout the duration of the event. The Spring Sakura and Sakuramochi Rabbit sets will be obtained by collecting Petals.
The general recommendation is to play the game as usual, keep farming items for your target suits, and use any extra stamina to play Maiden stages like 2-S2, 3-S1, 7-7, and 8-5, as these stages drop good items for decomposing for Rebirth materials, and will help maximize your participation in the event.
Good luck, and happy styling!
