==History==
Indebted to Kazumi after he helped save the life of his grandmother, Massugu Ubukata wished to join him and the Crows in their crusade in Touto. To that end, he crafted a set of dog tags for all five of them. However, he was declined by Kazumi. 
The Hokuto Sanbagarasu interrupted a fight between Grease and Cross-Z Charge, only for Kazumi to state that they broke the rules of engagement and relinquish the Kuma and TV Fullbottles to Ryuga as his penance. Having followed Kazumi to Touto, Massugu tracked the Touto Riders to nascita and, in an attempt to earn Kazumi's favor by reclaiming the Fullbottles, used a Smash Bottle to expose himself to Nebula Gas and transform into an Ice Smash. Though he was ultimately defeated by Sento Kiryu, Sento came to understand his story thanks to Televi-san, and returned the Kuma and TV Fullbottles to Grease while suggesting to Massugu that he would to better to return to Hokuto and continue supporting his grandmother. Left with Massugu, Kazumi realized that he was still holding on to the dog tags he had made for him and his comrades and chose to finally accepted them, claiming that the jingling sound Massugu made when he walked irritated him. 
===New World===
After Evolto's demise and Sento fuses the two worlds together, All members of Hokuto Sanbagarasu are alive and seen entering Nascita with their boss Kazumi. When Kazumi is passed out because of a meeting with Misora, the group carries him out of the cafeteria.
Upon the arrival of the terrorist organization Down Fall, Kazumi and the Hokuto Sanbagarasu battled the Phantom Crushers. However, the trio are defeated and hospitalized by Keiji Uraga as Kamen Rider Metal Build. They willingly subject themselves to a painful, potentially lethal procedure that will allow Sento to extract the Phantom Liquid in their bodies in order to restore the powers of those neutralized by the Phantom Crushers and complete the Grease Perfect Kingdom, which was used by Kazumi as Kamen Rider Grease Perfect Kingdom form to defeat Metal Build.
After Uraga's death, the Hokuto Sanbagarasu reunite with Kazumi, revealing that Sento had deliberately misinformed Kazumi about their deaths in order to raise his Hazard Level for the fight against Down Fall.
