Saki and her party continued to traverse the underground of Tokyo and finding all kinds of mutated creatures. The group arrived at an underground river, and Kiroumaru suggested the group split in two. Saki and Inui went back to the beach to retrieve the submarine and navigate the underground river. After the apparent sacrifice of Inui, Saki found a facility and took a strange item (probably the Psycho Buster). Throughout all this Saki remembered Shun and apparently found him in the flesh at the end of the episode.
Episode 23 of From the New World continued the build up for the grand finale. Besides the potential presence of Shun and its implications, Inui was also mistrusting of Kiroumaru because he appeared to suspiciously know too much about Tokyo. This episode was very good, but I do not see much excitement, considering that the series has only two episodes left. Hoping that From the New World has a great conclusion, I give this episode a 9 out of 10.
