In Chisa's route, she and Shun continue solving the puzzles left by their grandfather. When the final question is blocked, Rin arrives and gives the answer.
In Chisa's route, she and Hayato also confront Kido at the old residence. After the key was retrieved, everyone gathered again at the old residence, and Qiansa handed it to Ying.
