Thor and Rai are twins who live on an advanced space colony called ‘Juno’. Things take a nasty turn one day when they are kidnapped by the Federal Army’s Special Forces and abandoned on the hostile prison planet Chimera. A cycle on Chimera consists of 181 days of scorching heat and 181 nights of below-freezing temperatures – not to mention it is populated almost entirely by carnivorous plants. The convicts on Chimera have found only one means of survival – reverting back to the law of beasts. For the strong-willed Thor adjustment comes naturally; but for his naive and weaker brother Rai, things do not go as well. Thor must now use all his wits, strength and courage to endure life as a member of Chimeran society, rise above the rest, and take the only ticket off this planet: becoming the Beast King.

Since long ago, the wolf goddess Holo has honored a contract to bless the rural village of Pasloe with fertile harvests; and in return she has been celebrated and worshipped by the villagers. But as mankind advances, the people have begun to take command of nature for themselves and have made their own god to worship. Holo finds that she is paid little more than lip service, if not outright mocked; and considering the contract annulled, she takes human form and enlists the aid of a passing merchant, Kraft Lawrence, to return to her home in the snowy forests to the north. As they journey together, Kraft finds that he has plenty to learn from this capricious god, and she from him as well.

The story revolves around Raina Ryuuto, an apathetic student who always dozes off at the Roland Imperial Special Academy. One day, Raina and his classmates get caught in the war waged by the opposing Kingdom of Esutabūru, and he loses many friends.

On the whole both take place with a 'medieval fantasy' setting. Plot-wise they remain difference, but there is a similar feel in a 'save the world' way.
Male and female lead who are both very capable (and the female being relatively terse characters).
Legend of Legendary Heroes focuses more on political intrigue.
