“What goes around comes around… in an endless cycle of pain.”

Hagane was born the son of a blacksmith and a toymaker. His first gift was an iron top which entertained him for many years, eventually becoming his lucky trinket that he keeps on him at all times. As he got older, his parents would find more advanced toys to give him, including his first yoyo when he was a teenager. He would learn many tricks with this toy, picking up various trade skills from his parents that gave him the skills to modify his own possessions, including adding blades to the sides of his yoyo and top. He would use these modifications to create weapons used to fight bullies and criminals in sketchy parts of towns he would visit, until he encountered his first demon. At that point he would attempt to create weapons strong enough to fight these creatures, but to no avail.

It wasn’t until a demon killed his father when Hagane began to take his fighting prowess seriously. He would train for years, learning everything he picked up from his parents to create the ultimate weapons that he would use regularly, becoming a master of the “yoyo and top” style. However, demons were still too strong, and too often he would find himself escaping for his life. It was not until he ran into another demon slayer where he learned the art of breathing, which he trained himself to do while having no other choice. After becoming one with his breathing and his unique fighting style, he was chosen to participate in the final selection, surviving the trial and, rather than receiving a sword, instead was offered to have his weapons of choice upgraded with new ore, which he happily accepted.

Once his new upgraded weapons arrived, he took this opportunity to go back to his father’s workshop to slay the demon that took his life. However, with his years of training, the victory was underwhelming, as he believed he showed it too much mercy with the swiftness of its death. He would then set out to find more demons to kill, this time focusing more on more brutal and painful methods that would cause as much pain and suffering as possible.

Metal Breathing
The Metal Breathing style is similar to Stone Breathing, however rather than visualizing controlling the Earth around them, instead they focus more on consolidating its elements into a much more durable material. The user visualizes various ores being smelted into one dense material in areas that are either striking or blocking, focusing on efficiency rather than raw power and endurance. Metal breathing offense utilizes maximum precision as well as expert knowledge on enemy anatomy and full distribution of force throughout as much of the users body as possible for maximum damage with the least amount of strain as possible. Likewise, defense with this breathing includes techniques inspired by the Wing Chun fighting style, utilizing full compression strength of the arms and legs to absorb more force than that of a typical block, which becomes even more substantial when used with a weapon.

Onigrinder
An oversized yo-yo with a retractable blade, held by a wound-up roll of wire. Breathing style allows the user to control the spin of the head as well as the position of the blade as appropriate for the intention of the attack.

Ripspinner
An oversized top with a retractable blade along the perimeter. The user uses their breathing style to control its rate of spin as well as its movement, using special buckles to hold their feet in place as they ride on it. Rate of movement with breathing is limited, but can be manipulated to have the blade gain traction on various surfaces to travel at faster speeds.

Onigrinder - First Form: Eli Hop Strike
Basic attack where user launches Onigrinder using free hand to jut out the head in a direction of their choosing. Most basic attack with Onigrinder.

Onigrinder - Second Form: Walk the Dog
User releases Onigrinder to latch to the ground and gain traction for a high-speed rolling charge at the enemy.

Onigrinder - Third Form: Sleeper Shield
User launches Onigrinder into a sleeper spin, holding it out in front of them to block incoming attacks. The blade can be expanded to increase the size of the shield while adding an offensive element to anyone that tries to bypass it.

Ripspinner - First Form: Let it Rip!
Basic attack where user throws Ripspinner towards enemy with an expanded blade. Can be thrown vertically to gain traction on the ground for a higher velocity.

Ripspinner - Second Form: Spinner Drill
While it’s spinning, user expands the tip of the spinner out to take the form of a giant drill and burrow through anything in its way. An effective method to maneuver underground or take shortcuts through plateaus, mountainsides, or just very large hills.

Ripspinner - Third Form: Engraving Spiral
User expands blades along Ripspinner's perimeter and latches onto a large enemy, stabbing it repeatedly as it rides around it in a spiral until it reaches the top.

Combination - First Form: Pulverizing Flail
While riding on Corpsespinner, the user launches it forward and throws out Onigrinder to latch onto the top, expanding its blade to create a stack of spinning blades controlled by the wire attached to the yoyo, combining its shredding power.

Combination - Second Form: Ironstrom
User latches wire from Onigrinder to the spinning edge of Ripspinner while riding it, causing it to rapidly revolve around them at high speeds while dealing damage within a massive area, usually good for weaker demons in large quantities.
