Ep. 2: Kennosuke Activates the Black Relic to Battle the Yellow Oni Mecha

2

While a princess once asked about foreign lands, a massive yellow mecha now lands on the coast with smaller units. The Ministry of Defense detects hostiles globally. Director Shirahane, Paula, Jiro, and Dr. Hausen attempt to question Kennosuke, but he escapes with Yukina, realizing she is not the princess. Kennosuke summons a black cube that transports them to the Black Relic. He activates the relic, smashing through the facility with Yukina aboard. Defense forces fail to harm the yellow mecha, so Director Shirahane orders them to cease fire against the Kurobe codenamed Giant. Kennosuke engages the yellow mecha, which he calls an Oni, using long glowing swords. Four additional Oni arrive, but Yukina assists as navigator, allowing him to defeat them. Just as he prepares to destroy the yellow Oni, it is lifted into orbit by a green beam toward a space station.
