Kuromukuro

クロムクロ

Yukina Shirahane, a high schooler in Toyama whose mother heads the UN Kurobe research lab, accidentally triggers a relic the lab has been studying and revives Kennosuke Tokisada Ouma, a samurai sealed away since the Sengoku era. Kennosuke can pilot the recovered alien mecha he calls the Black Relic, but only with Yukina navigating from the second seat. When the alien Efi Dorg renew their assault on Earth, the two are pushed into the same fight Kennosuke first took up centuries earlier.
