Description
Gammon Sakanoue is a freshman student at Root Academy who serves as a self-proclaimed rival to the series' main protagonist, Kaito Daimon. He is a tall young man with a distinctive appearance, featuring spiky red hair with two long strands falling over his face and piercing gray eyes. His characteristic outfit of a leather jacket and matching pants cultivates a deliberate delinquent image, which is further supported by his brash way of speaking and his habit of riding a motorcycle.
Operating under the official Solver title of Galileo, Gammon's approach to puzzles is markedly different from those who solve for the sheer love of the challenge. His primary motivation is financial, as he tackles puzzles for the monetary rewards needed to support himself and his younger sister, Miharu Sakanoue, in the absence of their parents. To supplement this income, he secretly works as a respected puzzle writer for magazines under the alias Chidousetsu. Underneath his abrasive and competitive exterior lies a deep sense of familial responsibility. He is a capable cook who regularly prepares meals for his sister, who cannot cook for herself, demonstrating a caring and domestic side that contrasts sharply with his rebellious facade. Another personal motivation is his unrequited romantic feelings for his classmate Nonoha Itou, which are earnest enough to compel him to participate in a cross-dressing contest solely to capture her attention.
Gammon's personality is defined by a fierce and hot-tempered rivalry with Kaito Daimon. He frequently mocks Kaito with derisive nicknames such as Bakaito, a combination of Kaito and the Japanese word for idiot, or Freakaito. Despite this antagonism, the two share several notable similarities, including their explosive tempers and exceptional puzzle-solving talents. Gammon is recognized as a highly skilled participant who can function effectively both as a Solver, who cracks puzzles, and a Giver, who creates them. He is considered a top candidate for developing a full Phi Brain, a state of ultimate puzzle enlightenment, though he remains notably the only main character in his group who has yet to experience a vision of the future.
Gammon's role in the story evolves significantly from that of a simple rival to a more complex and antagonistic figure. Initially, he competes with Kaito to claim treasures offered by the enigmatic organization POG. This rivalry becomes strained when he realizes that Kaito operates on another level of ability, particularly when using the power of the Orpheus Bangle. This perceived inferiority festers, especially after POG discovers his secret identity as the puzzle writer Chidousetsu and recruits him. After passing a test administered by the POG leader Bishop, Gammon aligns himself with Rook Banjou Crossfield in the pursuit of the ultimate Puzzle of God. This event triggers a drastic shift in his character; what was once a competitive rivalry curdles into what appears to be sheer hatred. He actively obstructs Kaito from solving the final puzzle, driven by a desire to prove his own superiority as both a Solver and a Giver. He engineers a deadly puzzle confrontation specifically to crush Kaito, though his true, deeper motives remain ambiguous enough that the skeptical POG leaders question his loyalty.
Development in Gammon's character arc culminates in the final conflict, where his essential decency reasserts itself. He joins Rook's plan to thwart the malevolent entity Orpheus, faking his own death alongside the solver Freecell. This deception allows him to evade Orpheus's detection, rescue his allies, and activate a device that halts Orpheus's control over Kaito. The plan ultimately succeeds, realigning Gammon with Kaito's group and resolving his brief turn to outright antagonism. In terms of notable abilities, beyond his raw puzzle-solving intellect, his talent as a Giver is so refined that he supports himself financially through his published work. He has a keen observational skill, capable of spotting solutions that others miss, such as recognizing Kaito's innocence during a confrontation involving Freecell and improvising a response where others saw no option. The origin of his name is a reference to the board game Backgammon.
