[2] In 2016, an adult animation series telling the origin of Richard, debuted on the public French TV channel France 4.
Since it is a duo tournament, the young boy is forced to give up his dream... until Richard Aldana, a hunk with bearish manners comes out of nowhere to unexpectedly ally himself with Adrian.
Brash, headstrong, and hot-tempered man but with a good heart, extremely resourceful, and never yielding attitude with great boxing skills.
Where he meets Siri and his boxing mentor, fighting demons which are long-dead original royalty from a magical parallel world called "The Valley of Kings".
They are betrayed by his boxing mentor's brother in containing the final demon and he ends up losing the orphan Siri who was like an adopted daughter.
In the first comic series, he travels to "The Valley of Kings" as Aldana uses his smarts and skill to assist Adrian and his mother Marianne, in the tournaments.
Aldana becomes further despondent and aloof from 10 years of imprisonment while blamed for the death of his loved ones and ever-increasing monster incursions in "The Valley of Kings".
Aldana is blamed for his brashness and the resistance team once again tries to find a way to fix "The Valley of Kings" by confronting the wizard in a dying world.
The knight knows Aldana's memories of Siri, his mentor, his best friend, and the love of his life and that it was the wizard who has caused their loss and the damaged portal introducing the monster incursions.

The Huffington Post points out that "Vivès uses the classical codes of martial arts tournament manga only to crush them more efficiently with his bearish and ruthless Aldana".
The show was made available for streaming on Netflix in France and Belgium in 2018,[10] and also on the Mondo Media VRV channel in the United States.
