Kuromukuro

In the early years of the 21st century, Japan’s United Nations Kurobe Research Institute is founded to examine a mysterious relic unearthed during construction of the Kurobe Dam. Researchers from across the globe converge on the facility, while their families settle into daily routines nearby, with many of the children attending Mt. Tate International Senior High School.

Yukina Shirahane, a quiet student and the daughter of the institute’s lead scientist, visits the lab and unexpectedly unlocks part of the artifact’s mechanism. The discovery brings forth Kennosuke Tokisada Ouma—a young samurai from the Sengoku period—thrusting the past into the present.

When an extraterrestrial threat closes in, Yukina and Kennosuke are drawn into the fight to defend Earth from invasion. As the conflict escalates, Yukina begins to uncover the truth of Kennosuke’s origins and the personal resolve that drives him to protect her.
