|“||Hoping to use your tools without subjecting them to any wear is mistaking the means for the end. In order to serve Tsuzura Temple's purpose, I'll exhaust as many tsukumogami as necessary.||”|
—Masuji Madarai, Chapter 106
Masuji is a short elderly man with a pointy moustache and a small goatee on his chin. He is mostly bald with only hair on the back of his head and a small amount of hair on the middle which stick out. Despite his age, Masuji is physically fit with well defined muscles.
Masuji's regular clothes consist of a kimono with tassels on the side of each chest.
Masuji is extremely arrogant, believing himself to be the most capable combatant. After watching Kukuri's battle with Kanaka Kagami, he believed the threat Kanaka posed to have been over exaggerated and stated Kukuri should be ashamed for having lost. He talks down to Kazuya Kagami despite knowing he is capable of Ascension which is highest obtainable goal of the temple's exorcist, achieved by none so far. Along with his arrogance, Madarai is easily angered when opposed or when his plans fail. Masuji does not view tsukumogami as people but rather tools. Masuji believes that the temple's reliance on a few strong individuals with a close connection to their tsugumomo to be detrimental when the rest of them can perform just as well by treating their tsukumogami as tools and exhausting them as they see fit.
Masuji orchestrates a plot to overthrow Ouhi Oriobana as head priest of Tsuzura Temple while she meets with Kazuya Kagami about situation Kanaka Kagami. While she is away, Masuji has Ouhi's followers detained, the tsugumomo from Mayoiga locked away and uses Arumi Ashimine's ability to replay Kukuri's fight with Kanaka. When Ouhi returns to Tsuzura temple with Kazuya he has Takumi Tagusari along with his other exorcists detain them. While the two are imprisoned Masuji explains his plans, goals and motivations to them. Ouhi and Kanaka manage to escape freeing Ouhi's followers in the process. Ouhi and Masuji's group confront each other and Ouhi challenges Masuji to the Nine Masters Tournament to determine leadership of Tsuzura Temple. A crowd gathers around the group and leaving him has no choice to accept Ouhi's challenge. Kazuya and Ouhi are able to free some the Mayoiga tsugumomo while the rest remain in Masuji's captivity. While Ouhi is bathing, Masuji and Kagashi use the incense burner tsukumogami Hakuenko to put Ouhi to sleep and interrogate her about the whereabouts of the temple's Puppet Bindings. They would later use Hakuenko to interrogate Ouhi again to gain information about their team.
In the Nine Masters Tournament assigned Kazuya as his opponent. Madarai has the fighters on his faction use Puppet Bindings on the captured Mayoiga tsugumomo, allowing them to secretly use multiple tsukumogami, with Takumi Tagusari and Suguru Susuzumi being the only ones not to, Suguru insisting he does no need it. Shiori Shioiori is given an additional puppet binding to self activate in her match against Ouhi should Shiori ever admit defeat. Even when his scheme is revealed, Masuji is still confident his faction will win. After Takumi's defeat at the hands of Takano Tagusari, Masuji lashes out at Arumi and Mimane Miyou for his team losing despite all the effort placed in their strategy, including using Arumi's power to predict their victory. Mimane explains that the further Arumi looks in into the future the more unreliable it gets. Masuji has Mimane use her power to observe Ouhi team meeting.
Madarai and Kazuya face off in the final match of the tournament. Madarai uses his his warehouse tsukumogami Chuushingura which he also uses to store the remaining bound Mayoiga tsugumomo. Masuji uses Sanjou to nullify Kazuya and Kyouka's sound attacks but the two are able to free Sanjou from his bindings and unarm Masuji. Masuji continues to fight unarmed until deciding to use Chushingura and his remaining puppet bindings to bind the remaining Mayoiga tsugumomo to him, transforming him into grotesque monster while using all of their abilities. Kazuya is enraged and enters Domination which proves to be too much for Masuji. Just as Masuji is about to be defeated, Kazuya's Domination wears off having Exhausted Kyouka to the point of breaking. As Madarai is about to finish Kazuya off, Kazuya is saved by Kiriha. Kiriha and Kazuya use Ascension and defeat Madarai, freeing the remaining tsugumomo in the process.
Madarai is imprisoned and transformed into a immobile mass of flesh and hands as a side effect of using the puppet bindings. Ouhi and Madarai strike a deal in order for him to use Chuushingura to restore damaged the Mayoiga tsugumomo. Ouhi later returns to fulfill her end of the bargain. Though the details of Madarai's request are unknown, they documented and told others that Madarai had himself sent to a regional branch due to his decreased popularity as a result of his actions.
