Botaro is KTM's right-hand man and wields an orange, mountain-shaped spear. He is cheerful and serious, an indispensable presence to KTM. Though he occasionally goofs off, he possesses a kind heart and enjoys high support from the citizens. He is friends with Hishi, Kan, Marutaro, and Marujiro, but they are rivals for this battle. He is intensely loyal to KTM. His techniques include "Spear Rain," which generates countless spears that fall like rain; "Omnidirectional Thrust," where he creates clones to surround and pierce the enemy simultaneously; and his ultimate move, "Fierce God Thrust," a light-speed charge with his spear leveled. He has a younger sister, a girl named Boka.

KTM's left-hand man, wielding a light blue naginata. He is highly loyal to KTM. He has a boisterous, outgoing personality and is rarely serious. He makes friends easily and is close with Botaro, Kan, Marutaro, and Marujiro, though they are enemies this time. He is incredibly strong, and like his younger brothers Sanka and Goka, he is heavily muscled. He has the appearance of a popular, energetic guy. His techniques include "Mowing Encirclement," using his naginata to sweep and trap enemies; "Hishield," a defensive barrier; and his ultimate move, "Shape Mow," where he leaps high and releases a massive slashing wave. While Botaro is specialized in offense, Hishi is balanced in both attack and defense.

KTM's "legs," he uses railgun cannons attached to his body as weapons. He is airheaded but extremely serious. He is fiercely loyal to KTM and highly popular with the public. He is relatively quiet. He is considered the most handsome man in Nuikai, though he is unaware of it. Consequently, he receives much affection from women other than his sister Kuka, including Botaro's sister Boka. Botaro and Hishi are jealous of him, but he remains oblivious. His techniques include "Volley Fire," firing all railguns at once; "Precision Shot," using a scope in his eyes to accurately pierce enemy weaknesses; and his ultimate move, "Absolute Destruction Ray," which enlarges his cannons to fire a beam of immense energy.

Micro's subordinate and Marujiro's older brother. He is laconic, works at his own pace, and is poor at group activities. He has the special ability to create and manipulate swords of any shape. His techniques include "Sword Dance: Descent," raining swords from the sky, and "Sword Dance: Ascent," thrusting a giant sword up from the ground. His ultimate move involves creating a sword of infinite mass to generate a small-scale "Black Hole," though he never uses it.

A priest who judges the dead and Marutaro's younger brother. He is cheerful, energetic, and loves to talk. He carries a glowing white axe called the "Guidance Axe."

His techniques include "White Star," throwing multiple axes like homing missiles, and "Satellite Impact," creating a shockwave by stacking multiple panels with the instruction "Blow Away."

An extraterrestrial being with very low intelligence. His personality is childish and eccentric; he speaks only in mysterious riddles, making normal conversation impossible. His special ability is the power to manifest any phenomenon he thinks of, provided it has some degree of feasibility. He also employs familiars called "Mini Pepes." He loves cold miso soup and can be negotiated with using it, though he immediately forgets the terms of any deal. His techniques include "Ribbon Punch," which lowers the target's intelligence to his level, and "Peperize Party," which turns the surroundings into a bizarre, cartoon-like world.
