第 12 集: 祭典告別前，Hitomi 重拾色彩後重返未來
Hitomi has a talk with Aoi, who promises her that he's glad he met her and Hitomi works up her determination to investigate the reason she was brought back to this time period. The next day, everyone attends the festival and has a great time, while at night Kohaku's family throw a feast to wish her goodbye. The second day of the Cultural Festival reminds Asagi of Hitomi's last day and she convinces Yamabuki to let Aoi and her have some alone time exploring the festival together, but Aoi hesitates to properly confess. That night, all the students have an after-party where Kohaku and Hitomi conjure some magical fireworks. In her extreme happiness, Hitomi realises that once again, she has regained her sense of colors, but likewise only for that brief moment. Everyone then heads to the park after a satisfying day, their sadness returning as Kohaku prepares to send Hitomi back to the future. (Source: Wikipedia)
