Go To

In a World... where people live on sky islands above the clouds, strange monsters called Nemesis occasionally fall from the sky and wreak havoc in towns. The only people able to inflict damage to them are the Infected, humans who miraculously survived the normally lethal contact with a Nemesis and gained the power to manipulate Fantasia, at the price of some physical defect. While people call them for help when a Nemesis pops up, the Infected are nevertheless considered abominations and feared by the common folk.

The horned orphan Seth is one of them, and lives away from humans with his teacher/adoptive mother Alma. While he absolutely wants to fight Nemesis, his impulsiveness often stirs up more trouble than he would like, which doesn't help his or Alma's case. But soon he realises that fighting off the monsters that appear here and there is pointless if you don't go for the source: an entity called the Radiant, that no one has ever found, and may or may not actually exist. Joined by the bumbling Researching Sorcerer Doc and Mélie, a Trapper Witch with a Split Personality, Seth's first step in his journey will be to join a giant flying city, the Artemis Institute, home of many professional sorcerers. And to avoid getting too much on the Inquisitors' bad side, preferably.


Radiant is a French manga written and drawn by Tony Valente since 2013, probably the most popular Animesque comic in France along with Dreamland, and also the first one to get a publication in Japan − said edition was promoted by no less than Valente's idol Murata Yuusuke. The series is also available in German, Spanish, and also English since September 2018. There are currently 10 volumes out in France, with about six months between each one.

It got a 21 episode anime adaptation by studio Lerche in the Fall 2018 season.

Not to be confused with a (Japanese) manga called Soul Gagdet Radiant.


Radiant provides examples of:

  • Adaptation Distillation: The first half of the anime significantly changes the way the main beats of the story play out and removes the gags that have a very "French" humor. It also tones down the violence and blood, although it's not a particularly bloody series to begin with.
  • Adaptation Expansion: On the other hand, episode 5 elaborates on the role of the Artemis Institute and its relationship with the outside world. Episode 7 also briefly mentions animal experimentations, whose rejects end up roaming around the sewers of the city, while episode 9 follows the Inquisitor squad of Captain Dragunov in one of their ordinary days to show more of the "good side" of the Inquisition.
  • Animesque: One of the more assimilated examples. While of Western origin, it was able to be published in Japan and get an anime adaptation thanks to mimicking the publication style of a an actual shonen down to every single detail except the publishing schedule (the chapters are not published separately). Even the speech bubble are shaped as though the dialogue were originally Japanese. The comic is also published by a manga imprint.
  • Antagonist Title: "Radiant" is the place where the Nemesis come from and the goal of the protagonist Seth is to beat it.
  • Arc Words: Alma's line "You aren't born human, you become one", meaning that it's ultimately your choices and actions that determine whether you're a monster or not.
  • Attractiveness Discrimination: During the Cyfandir arc, Seth is baffled to discover that entering the Order of Sorcerer Knights requires that the sorcerer's infection isn't too visible − that they look every bit like non-infected people, basically. The argument is that Sorcerer Knights are supposed to protect the people, so they can't look "scary". This serves to show that there can be forms of discrimination even among the infected.
  • Background Magic Field: Fantasia, a magic power present in the atmosphere and used by the Nemesis to attack. People who have survived the contact with a Nemesis become able to manipulate it with the proper equipment − handling Fantasia barehanded normally burns the skin… except for Seth, which is one reason he's hunted by the Inquisition.
  • Beauty Is Never Tarnished: Thoroughly averted. If anything, the pretty girls and women are more susceptible to being injured and bleeding than the guys in this series. Queen Boadicée even keeps a large facial scar after the Cyfandir battle.
  • Brainwashed: The unfortunate effect of Ocoho's infection. Pressing a spot below her right ear will make her a slave to that person's will for a brief period of time, and she won't remember it afterwards.
  • Church Militant: The Inquisitors mercilessly hunt down sorcerers at the slightest misbehaviour, and even though they're not sorcerers, their skills and strength are nothing to scoff at.
  • Does This Remind You of Anything?: Konrad's speeches about the invading immigrants in the Rumble Town arc are unsubtly reminiscent of some of the views held by parties like the National Front in France or the UKIP in the UK.
  • Down the Drain: Episode 7 of the anime is a filler where Doc is abducted by a creature in the sewers of the Artemis.
  • Driving Question: What are the Nemesis and where do they come from?
  • Fantasy Counterpart Culture: Although little is explained about their culture, the refugees from the Far South in Rumble Town are quite clearly meant to represent Muslim populations from Maghreb or the Middle-East, from their clothing style to their food. This makes a lot of sense considering the author lives in France, where most non-European immigrants are from those regions.
  • Filler: Episode 6 to 10 are almost entirely anime-original, mostly expanding on the main trio's life on the Artemis and Seth's training with Yaga, as well as episode 9 focusing on the Inquisition's side. Strangely enough, some of it is about Seth learning things that he already knew from the start in the manga.
  • Great Big Book of Everything: The Book of Truth, which Doc finds in the library of the Caislean Merlin castle, gives the reader any information they need through a small roulette that indicates the relevant page's number. It supposedly can even indicate when the Radiant is. But of course, that page has been torn off.
  • Hellgate: It's not clear what the Radiant is exactly (even its existence is uncertain), but it designates the one place where all the Nemesis supposedly come down to Earth from.
  • Interspecies Romance: In the Cyfandir arc, Myr, a pixie, is married and has children with Yggdrajill, a dryad. Myr himself turns out to be half-human.
  • Long Lost Sibling: Subverted. Volume 4 introduces Piodon, who claims to be Seth's brother, despite the latter having no memories of him. It later turns out Seth has several "brothers" with a similar infection, who are all part of some sort of experiment by the same Piodon.
  • Not So Different: What both Don Bossman and later on Hameline argue against Seth, who suffered as much as they did from persecution. He admits to the latter than he more than once wished he could go on a rampage and let the non-infected have a taste of their own medicine. This is then reversed when Seth points out to Hameline that she could have done just that, but never actually had the guts to kill anyone.
  • Phlebotinum-Handling Equipment: Sorcerers use feather gloves to accumulate and manipulate Fantasia, as it's too dangerous to manipulate barehanded. However, this is inverted in the case of Seth, who can use Fantasia barehanded, but can't do it with feather gloves.
  • Sustained Misunderstanding: In the Rumble Town arc, Grimm keeps misinterpreting what he hears from Seth, Mélie and Doc, and adds his own ambiguous comments on top of that. This is partly played seriously, as Grimm initially treats them as enemies because of that, but it's also Played for Laughs when Grimm reveals afterwards in which way he misinterpreted their words. Case in point, Doc crying "My wife! My children!" when Grimm killed the Nemesis they had captured leads him to infer that the Nemesis were Doc's wife and children.
  • Team Pet: Mr. Boobrie, a horned bird… thingy who always follows Mélie and particularly loves her violent side. He's named after a mythological bird from Scottish folklore.
  • What Measure Is a Non-Human?: People have absolutely no qualms asking the Infected to sacrifice themselves. Later on, the same question is asked about the Nemesis: are they truly evil beings?
  • World in the Sky: The islands aren't floating, they're at the top of very high and narrow rock pillars, but the effect is similar. Zeppelins and hot-air balloons are the most common transportations (as well as flying broomsticks for sorcerers).
