A new multimedia franchise called "Khronos Gear" is being started by the Japanese mobile game company G-mode (makers of
Keitai Shoujo and
Sengoku Paradise: Kiwami - both adapted into anime). The three projects
announced so far include a manga, a game and, most notably, an OVA that's being created by studio AIC for release this summer.

The OVA is titled
Katayoku no Khronos Gear (Winged Chronos Gear) and features a sci-fi story set in the near future, after humanity has built an orbital elevator and begun colonizing the outer planets. An enigmatic extraterrestrial enemy known as "Obliquus" / "Oblicuse" has set its sights on the solar system, however, and upon their raiding of a space station, humanity enters a state of war with the aliens.
To counter the enemy's overwhelming technological superiority, the Khronos Foundation has assembled the descendants of every country's heroes from Japan's Musashi Miyamoto and Ryouma Sakamoto to France's Napoleon and Joan of Arc. The foundation then fuses the descendants with "Gear" battle suits as special biological weapons, thus giving birth to "Khronos Gear". (based on
ANN synopsis)
Among the OVA's voice cast is also Aoi Yuuki, who won the
6th Annual Seiyuu Awards earlier this year, for her leading role from
Madoka Magica. And just yesterday, she was also
announced to be part of the cast for this summer's TV anime sequel
Dog Days 2.
But getting back to the Khronos Gear OVA, you can get a feel for how it will look like from the few visuals released so far - see them in the anime's local
