The story of BOC Arena stretches from the busy districts of Jankenmura to the dangerous floating lands of the Void. Explore the places that shape the gang, the fighters, and the village's strange arena culture.
A bustling farmland village with ports, schools, spas, labs, markets, beaches, and an arena district.
Jankenmura means "rock-paper-scissors village." Long before the arena existed, villagers settled small disputes, market draws, and festival games with janken — the ancient hand ritual. When tournament culture arrived and grew into the fighting bird leagues, the founding game came with it: every fighter's rock, paper, and scissors move weights are the old village ritual living on in battle form.
Jankenmura is food-rich because its farms never really sleep. Crop terraces, grazing fields, wet-market stalls, and upgrade offices keep trainers supplied with the food and materials their fighters need.
Ginko's family lives in the more luxurious part of the village and governs the farmland economy. Her world-market ambitions turn local harvests into trade routes, rare goods, and opportunities for rookie and veteran trainers alike.
The south side of Jankenmura belongs to the arena tradition. Asuka lives with her father near the pagoda residence that watches over the district, where old human tournament rituals became fighting bird leagues. Its championship circuit is the Battle of Crowns — the tournament every trainer in the village dreams of winning.
Nearby, an Asian-themed casino gathers the village's appetite for randomness, lucky streaks, and risky bets. It is the place where chance feels almost like a local weather pattern — Ginko calls it bad math wearing lanterns, while Roll quietly suspects the luck is real and keeps taking notes.
The port district is where Featherman was born and where he still lives with his grandfather. His grandfather fishes all day, relaxes when he can, and raised Featherman after his parents were gone from his life at a young age.
The nearby beach is one of the gang's favorite places to disappear after school, training, or a bad day at the arena. It is the village's easiest place to breathe.
Altera works in the village egg and breeding laboratory, where incubators, lineage studies, and booster safety turn strange biology into careful research. A clinic nearby handles ordinary injuries and arena mishaps.
Jankenmura also has school campuses for elementary, senior high, and college students, while the northern hills hold the hot spring spa where the gang can recover when village life gets too loud. Trainers swear the mineral steam eases battle stress for humans and fighting birds alike, so post-match soaks are a village tradition for champions and losers both.
The mystical beast world beyond the dark forest rupture.
The Void is not empty space. It is a mystical beast world of floating lands, broken paths, strange terrains, dangerous challenges, and loot that tempts explorers deeper than they planned to go.
Some islands are tiny stepping stones. Others are whole biomes with forests, cliffs, ruins, crystals, water, fire, ice, or monsters waiting between one safe landing and the next.
The known entrance sits east of Jankenmura, inside the dark forest where the ground turns swampy and the trees stop feeling friendly. Nobody agrees on why the rupture opened there.
The portal is unstable, but the Voidwalker mage Roll can bridge it safely enough to guide roguelike expeditions into the beast world and bring the party home.
Local scholars have fought over a classic debate for generations:
The distant homelands of our village trainers.
Homeland of Asuka's family line
Kajimura, the Fire Village, is a hot, volatile town known for chaotic and unstructured fighting culture. Unlike Jankenmura's regulated leagues, Kajimura brawls are lawless, high-risk, and often destructive.
Asuka's family migrated from Kajimura to Jankenmura to escape this exhausting environment, seeking a place where martial arts could be practiced as discipline rather than survival.
Homeland of Altera
The Northern Snowlands are a vast frozen frontier of glaciers and high peaks. The harsh cold pushed its people toward preservation methods, careful records, and structured scientific habits.
Altera and her family transferred to Jankenmura five years ago. Her Snowlands education in temperature control and cellular preservation directly inspired her work on Jankenmura's egg incubators and booster safety refinements.
