Details of a new feature to be implemented in a future update

A new feature that allows you to get various items for accumulating friendship points.

In the update planned for this winter, we plan to implement a new feature that gives various item rewards for accumulating friendship points.
In this new feature, you will be able to obtain Main Skill Seeds through continuous gameplay.
Ahead of this feature’s release, after the 3.8.0 maintenance period, we plan to give out items depending on the amount of friendship points gained during sleep research from Sep. 14 (Mon) at 4:00 a.m. until the release of the new feature.
