Katayoku no Khronos Gear

In a near-future setting, humanity has constructed an orbital elevator and is actively exploring the outer planets when an unknown alien force called "Obliquus" threatens the solar system, prompting a conflict. To combat the aliens' advanced technology, the Khronos Foundation recruits the descendants of historical figures such as Japan's Musashi Miyamoto and Ryōma Sakamoto, as well as France's Napoleon and Joan of Arc. These individuals are merged with specialized battle suits known as "Gear," transforming them into elite weapons designated as "Khronos Gear."
