Description: Disputes across countries, eras and territories, heroes use biographies, and people use history to stack arguments. In the end, what awaits us? A Chinese brother and sister travel to Japan. Unexpectedly, as soon as they arrived in Tokyo, they were involved in an unexplained riot. They had to flee to a nearby shrine for refuge. Under the shrine, the two "traveled" to Japan 1,000 years ago... In order to commemorate the 20th anniversary of NEKO-NEKO, the first full-length series of "Historical Crossing Department" co-produced by Chinese and Japanese creators, written by Tomoka Kataoka independently, is condensed here.
