I've almost finished what there is of the main story so far. They've been keeping information about the 3rd protagonist, Nao, in the dark. But my personal theory is that she's the baby Rena's mom said she was pregnant with when divorcing Rena's father. Given that she comes from about 10 years in the future, the timeframe lines up. Furthermore, Rena reacts when hearing her last name, which could be because she recognizes it from the guy her mom was hanging out with. Nao meanwhile reacts to Rena's appearance which could be because she resembles their shared mother.
