4-Star Princes
4-Star princes can be obtained in-game in the case of Seras and Navi, or in the regular gacha. They have 5 chapters prior to Awakening and 3 after.
Collab-Exclusive Princes
Collab-exclusive princes can only be obtained while the collaboration event is running. They do not appear in choices for custom gachas, nor can they be exchanged for outside of the event. As such, it is difficult to acquire their stories.
