With no time to lose, Takeru aims to enlist Yuuko's help in his world to complete the Alternative IV project—the last hope humanity has against the BETA, an alien species invading the planet.

Barely escaping with his life, Takeru is left traumatized after witnessing the cruel death of one of his close friends.
