After destroying Earth many years ago, the alien race Gauna has been pursuing the remnants of humanity—which, having narrowly escaped, fled across the galaxy in a number of giant seed ships. In the year 3394, Nagate Tanikaze surfaces from his lifelong seclusion deep beneath the seed ship Sidonia in search of food on the upper levels, only to find himself dragged into events unfolding without his knowledge. When the Gauna begin their assault on Sidonia, it's up to Tanikaze—with the help of his fellow soldiers and friends Shizuka Hoshijiro, Izana Shinatose, and Yuhata Midorikawa—to defend humanity's last hope for survival, and defeat their alien foes. Sidonia no Kishi follows Tanikaze as he discovers the world that has been above him his entire life, and becomes the hero Sidonia needs. [Written by MAL Rewrite]

Hiroshi Shiba is an outstanding car racer whose father is assassinated upon the discovery of the Bronze Bell from an ancient civilization.

With these abilities and the help of his father's brain implanted in a computer and his assistance Miwa "Micchi" Uzuki, they set out to neutralize Himika's plans of world dominion.

In the distant future, humanity has taken to the skies and colonized many planets throughout the universe. An agency known as the Galactic Organization of Trade and Tariffs (GOTT) has been formed to maintain order. Within GOTT, a secret squad of enhanced human beings—known as the ES Unit—carry out secret missions to put a stop to major galactic crimes. Two such operatives are the lowly C-ranked Éclair and Lumière. Despite being on the bottom of the totem pole, the pair wield formidable powers: Éclair's superhuman strength and lipstick whip and Lumière's ability to take control of any computer. Together, they can take on any mission that GOTT throws at them. But as they complete more and more missions, the duo begin to uncover a major conspiracy that leaves them questioning everything they know about themselves and the entire galaxy.

Twenty-five years after Éclair and Lumière, (from the flagship Kiddy Grade series), rescued the galaxy from destruction's doorstep, the GTO (Galactic Trade Organization), created after the defeat of the GOTT (Galactic Organization of Trade and Tariffs), act on behalf of universal peace by combating criminal activity. Their special ES division mirrored after the GOTT's ES (Encounter of Shadow-work) force, now includes publicly acknowledged ES member candidates. The series follows two such trainees, Ascoeur and Q-feuille, as they work their way to ES membership. (Source: Wikipedia)
