It's a hard reboot of an older webcomic called [Fan Dan Go].
It generally updates every Friday on Tapas.
Errant contains examples of:
- Aerith and Bob: Character names range from Elrekia and Subo to... Juliet.
- Alternate Universe: Britannia is a Britain where King Arthur was real, so the culture retains Romano-Celtic elements like Latin cuss words and people swearing to Sulis Minerva.
- Animesque: The style has a mixture of manga and western comics and cartoon influences.
- Anime Hair: There's barely a person in the comic with a standard hair colour. In Britannia, You Gotta Have Blue Hair literally because the more magic you have, the more bright and unnatural your hair colour will become.
- BFS: After the Time Skip, Rekki has a new sword to replace the one she broke in the prologue that's ridiculously huge. Of course, Rekki does have Super Strength but there's an element of Rule of Cool here too...
- Color-Coded Characters: Each character has a strong theme colour, particularly after the prologue, usually based around their hair colour.
- Cool Sword: It's practically a requirement to be a main character in this comic.
- Excalibur: The main plot item of the story is the legendary sword Excalibur, which, when drawn, opens an "Age of Knights", increasing the amount of magical power in the world for humans but also unleashing marauding demons.
- Magic Knight: The comic is all about them.
- Nice Job Breaking It, Hero!: The comic's main plot kicks off after Urien draws Excalibur and tries to let a demon take Sarin's body, Rekki still chooses to become one of his knights.
- Red Oni, Blue Oni: Rekki and Sarin play this trope very straight. Rekki is strongly associated with the colour red and is physical and hot-blooded, while Sarin is associated with blue and is hesitant, thoughtful, and more of a magic-user.
- Time Skip: "Ten Years Later..."
- Unsound Effect: Examples so far include "Sword." and "Crisps!"
- Urban Fantasy: The comic takes place in a world where there are knights, demons, and magic, but the technology is fairly consistent with our own world, so people tweet (or "sqroll") hot takes about the knights, demons, and magic.
