Youll start Part 5 and return to the school when you have completed the boss battle with Garurumon and Monzaemon in Digimon Survive. This is when youll get a chance to revisit and interact with a few characters, although not all, and strengthen your bonds with them.
If we become sacrifices, then, how should you respond to Saki?
Saki is found in the gym during this Free Action phase, and she is clearly interested in what Garurumon and Monzaemon were referring to during your previous encounter. The answer you should choose is We can go home, which will increase your bond with Saki and increase her ability to communicate in battle later in the game.
If you don't give the correct answer to Saki's question, you'll get a time-sensitive situation. When you arrive, Saki is being changed, and you'll eventually discover someone hiding somewhere in the gym. However, before you're found, someone touches Saki inappropriately. This scene starts a side quest you can complete by uncovering the person who was spying on and touching Saki at the time.
