Ragna Crimson

A normal high school boy Kisaragi Ryuji's peaceful life is turned into an adventure by the return of his second cousin Eriko. Ryuji and Eriko seize a relic box from a black broker. In the box, they find a red dragon girl Rose. In order to protect Rose from the black organization, Ryuji decides to fight using his power as a relic handler.

Long ago, the most ancient of divine dragons was slain by a human. The mighty dragon accepted its death when suddenly, it was reborn as Dolan, a man who lives in a quiet village. While spending another peaceful day toiling in the fields, he meets Celina, a half-human, half-snake creature looking for a partner. The unlikely duo become friends, but challenges lie ahead that threaten their new bond.

The story revolves around "jushiki" (lit. spell equations), the equations that govern the quantum constant "h" of action, change the laws of physics at the local scale, give birth to TNT explosives and poison gas, and cause incredible physical phenomena such as plasma and nuclear fusion. Two "jushikishi" (spell equationists) who use jushiki in battle are Gayus (who deals with bad luck with tact) and the beautiful but cruel sword-wielder Gigina. These two bounty hunters are caught up in a battle with dragons in the city of Eridana and in the intrigue of great nations.

The Quin Zaza airship sails the skies in pursuit of the deadliest (and tastiest) magical monsters in the blue: DRAGONS. While most people fear these scaly beasts, the crew of the Zaza specializes in bringing them down to earth to offer the world the medicine and food only dragons can provide. It’s a tough living, and the price for failure is all too often death, but the rewards for success are riches immeasurable — not to mention the most delicious cuisine around! Note: All episodes premiered on Netflix on January 9, 2020, but aired weekly on TV.
