Otr of the Flame (灯火のオテル, Tomoshibi no Otr) is a Fantasy Shōnen manga by former Kōhei Horikoshi assistant Yuki Kawaguchi (The Hunters Guild: Red Hood). The manga was serialized in Weekly Shonen Jump from May 11, 2025 to January 19, 2026.Otr is a boy who joins the army as a cook, though he dreams of becoming a warrior like his father. When the fortress he's in gets attacked by the forces of the Ice Kingdom, he suddenly forges a bond with a fire spirit named Fylgja and gains the strength to defeat his enemies.
Otr of the Flame provides examples of:
- Creator Thumbprint: Like in Hunter's Guild, the protagonist is a tiny, but powerful and kind-hearted young boy from a small village. Likewise, one of the major characters is a huge, busty, and muscular Amazonian Beauty (Alajoki), like Debonair Diamond in the previous manga.
- Endless Winter: The Forest Kingdom has been covered in snow and ice ever since the Ice Kingdom invaded. Otr notes that it should normally be summer around the time the story starts.
- Gotta Catch 'Em All: The spirits and their boons turn out to be central to the conflict of the story. The Ice Kingdom had been secretly finding and gathering the power of various spirits, and destroying the locations of the ones they couldn't recruit. The King of the Forest Kingdom has created a special task force to find and recruit their own spirits to fight.
- Honorable Warrior's Death: Many of the Forest Kingdom's warriors fight in hopes of making it to Valhalla after death. However, as stated by Fylgja, someone who seeks their own death can't live to their fullest; by comparison, Otr's decision to keep fighting in a desperate attempt to save everyone's life rather than accept his death is what lets him slay the Ice Kingdom's forces and protect everyone, with Alajoki pointing out that his mindset is the only reason why everyone at the fortress and their families back home are currently alive.
- Lady Land: Played with in regards to the elven lands. In theory, they are all women and look the sort, however, as Otr explains, Elves are actually an entire different race rather than humans; they aren't dimorphic and there's no such a thing as male or female elves.
- Karmic Jackpot: Otr obtained the powers he did from being a naturally warm-hearted boy who was ready to sacrifice his life to the Holy Flame in an attempt to save the lives of the fortress's warriors, and his attempt to do so is what awakened Fylgja and allowed him to gain her power.Fylgja: Your heart was the warmest on that battlefield... and I think that's all there is to it.
- Klingon Scientists Get No Respect: Subverted. Otr is a young boy who goes to war as a cook and meadwarmer rather than a warrior, making him worry that he'll never meet his late father in Valhalla if he dies on the battlefield as a non-combatant. Alajoki rebukes the notion, claiming that everyone on the battlefield is a warrior and that his place is in the kitchen keeping everyone alive.
- Life Energy: The heroic vigor is a life force used by trained warriors.
- Magic Must Defeat Magic: The ice created by a spirit can only be melted by the flame of another spirit. This makes Otr and Fylgia uniquely important as the only people who can counter the Winter Spirit.
- Muscles Are Meaningful: Sixten is both absolutely huge and absolutely shredded, being introduced easily tearing a tree in half lengthwise before casually bringing over a fish as large as he is to cook over a fire. The entire reason Alajoki sends Otr to become his pupil is so he can hone his body enough to use Fylgja's power without exhausting himself too quickly, and she herself learned under him to become the muscle-bound warrior she is in the present.
- Shout-Out: The scene of Otr protecting and cradling the Holy Flame with his body is very similar to a panel in My Hero Academia, which symbolically portrays All Might cradling a flame representing what he has One For All from a snowstorm.
