Ryan Akagi and Min-Gi Park

Ryan Akagi and Min-Gi Park are the dual protagonists of Infinity Train Book 4 (subtitled Duet). They are childhood best friends (born around the same time in the late 1960s in Powell Lake, British Columbia, Canada) who board the train together after a falling-out over their musical dreams.

Personalities

Ryan Akagi (Japanese-Canadian, voiced by Sekai Murashige) is the free-spirited, impulsive “Red Oni” of the duo. He is passionate about music (especially guitar/rock), a big dreamer, self-confident, and quick to act on instinct and emotion. He is adventurous, charismatic, and persistent about chasing rock-star fame, but his “leap before you look” approach often leads to shortsighted decisions and stalled progress. He can come across as a bit of a manchild or overly pushy, but he grows by learning to slow down, communicate, and consider consequences (and others’ feelings). He has a warmer, messier aesthetic (red glasses, leather jacket, ripped jeans) that reflects his energetic personality.

Min-Gi Park (Korean-Canadian, voiced by Johnny Young) is the earnest, down-to-earth, more cautious “Blue Oni.” He is hardworking, thoughtful about the future, humble, and somewhat stressed/worn-down. Passionate about music like Ryan, he is held back by self-doubt, parental pressure for a “stable” path (e.g., finance, a sensible instrument like viola), and difficulty expressing emotions. He has a bull-headed streak and can be rigid or condescending when trying to “help” by enforcing rules/plans. His growth involves embracing risks, apologizing, and letting go of overthinking and people-pleasing. He has a neater, more formal look (Members Only-style jacket, polo).

They contrast strongly but complement each other (Red Oni/Blue Oni dynamic), with Ryan pushing forward and Min-Gi trying to plan/ground things.

Friendship

They have been inseparable since birth (incubators next to each other) and bonded over music as kids, forming dreams of touring and making it big. Their friendship strained in their late teens/early 20s due to diverging paths: Ryan pursued music full-time (touring solo in his dad’s van after high school), while Min-Gi got a diner job and headed toward university/finance to please his traditional parents. This led to resentment—Ryan felt abandoned (especially after Min-Gi chickened out of a Battle of the Bands), and Min-Gi felt pressured and fearful of the risks (including concerns about racism facing Asian musicians). On the train, their dynamic is central: initial bickering and blame (numbers stuck high) give way to honest talks, mutual support, and mending. Key moments include reliving past abandonments, confronting insecurities (e.g., Ryan’s family issues, Min-Gi’s parental pressure), and choosing to stay together rather than exit alone. The season emphasizes communication, loyalty, and realizing they need each other to grow. Their bond is deep, platonic/brotherly (with heavy fan shipping), and ultimately strengthened.

Time as a Band

Growing up,, they dreamed up bands like “Chicken Choice Judy” and planned a Canada tour ending in New York. They wrote songs together. Min-Gi bailed on performances, leaving Ryan to go solo. Ryan had some gigs but limited success; Min-Gi sidelined music for practicality. On the train (especially the Party Car), they reunite musically, perform, compose new material (with Kez), and overcome fears—symbolizing the healing of their creative partnership.

Infinity Train Adventures (Book 4 - Duet)

They enter via a portal after Ryan impulsively steals Min-Gi’s keys and jumps in. Their numbers start at 202 (tied to their “duet”/pair dynamic). They travel with Kez (a chaotic service bell denizen who becomes their companion) through whimsical and challenging cars: Iceberg (time/thermostat chaos), Old West (trial by bug judge), Pig Baby (kitchen absurdity), Astro Queue (line vs. rule-breaking), Party (performance and fears), Art Gallery (cold arguments and near-separation), Mega Maze/Castle (Kez’s home, past regrets), and more. Adventures force them to confront personal flaws, help Kez with accountability, evade past “victims” turned pursuers, and learn lessons about impulsiveness vs. overcaution, friendship, identity, and pursuing dreams. Ryan gets an exit opportunity but stays for Min-Gi. They ultimately resolve their issues, grow individually and together, and exit the train. The book explores themes of Asian-Canadian experiences, parental expectations, creative fulfillment, and the power of reconciled friendship.

Appearance: Ryan (left) is a young man with fair skin, messy/wavy brown hair that falls over his forehead, and large reddish-brown framed glasses. He has a bright, toothy smile and wide eyes. He’s dressed in a brown leather jacket with epaulets and silver buttons over a green t-shirt, paired with light blue/cuffed jeans that have prominent rips at both knees, a black belt with a silver buckle, and maroon/brown boots.

Min-Gi (right) is a young man with fair skin, short neatly styled black hair, and a broad, friendly smile. He’s wearing a blue-gray zip-up bomber jacket (with ribbed cuffs and hem) over a white collared button-up shirt, gray/tan straight-fit pants, and white and gray sneakers.

Both characters are standing side-by-side in a casual, music-filled room (with an electric guitar behind Ryan and a keyboard behind Min-Gi), drawn in a clean 2D animated style.

The dim lights of the small basement studio glow warmly over scattered cables and music gear. Ryan (left), with his messy dark hair, red-framed glasses, brown leather jacket, green shirt, and ripped light jeans, stands proudly beside his red electric guitar propped on its stand. Min-Gi (right), cool and confident in his blue zip-up jacket over a white collared shirt, gray pants, and sneakers, stands next to his keyboard setup. The two best friends have just finished playing their latest original song together — a catchy indie-rock track they wrote and rehearsed for weeks. Ryan shredded a killer guitar solo while Min-Gi laid down solid keys and harmonies. The final chord still echoes faintly against the brick walls. They both turn toward you, still a little flushed with adrenaline and excitement, wide smiles on their faces.
