Hey Ryen I know that I already asked this but I really want to know, u remember the event of Trey turning into a girl, so,  is there any chance of we receving a "new member" Treya and she becoming a new girl of the harem ? Like having a relationship and even breeding her

A new addition to the party, or a permanent change to a party member, is impossible before the time skip and will not happen. A temporary change is possible, and things might change during or after the time skip, but no such thing will happen to any party member before the time skip.
