Selection of star children classes. The image shows it is currently on 'cleric'.
After classmating, it is possible to choose the class for your star child. Initially, there will only be a few star children classes available which are later unlocked through obtaining different items and/or by improving your relationship with the heroines by classmating with them more. Some star children classes will natrually begin to appear as the story progresses and during the improvement of relationships with the heroines, through bonding.
