Main wearer of the Faiz Gear, eveb though he was at first reluctant. He is a apathetic loner who prefers not to get into relationships with people because he fears he will betray them. He is often teased by Mari for being a 'nekojita' (Literally means "cat tongue"; a person who can't bear food that is too cold or hot). When the reunion of the Ryuusei School students turned into a massacre caused by the Clover Four's Kitazaki and Takumi attempted to protect them. However, Mari caught him on film and everyone believed he was responsible for the massacre. It is revealed that he too is an Orphnoch. He was originally a human until when hit by a car as a boy and died. He was resurrected as the Wolf Orphnoch, choosing not to use his power unless necessary but to protect humans. Since the massacre, he refused to transform until he was forced to when Mari was dying from injuries caused by Sawada.

By present time, while at a restaurant, Takumi sees Mari there and follows her under the notion that the bag she carried was one stolen from him three days prior, demanding the bag from her when two of her traveling companions dissolved and she assumed he killed them. But when the true killer, the Orphnoch Hiroshi Izawa, reveals himself and takes the Faiz Gear, Mari put the Gear on a reluctant Takumi, becoming Faiz and kills the Stingfish Orphnoch. Once the police find his bag, Takumi ends up with the Faiz Gear when he and Mari got their bags mixed, coming to her aid when she is attacked by the Elephant Orphnoch. But once learning she was faking her injuries, Takumi ditches her and causes a laundry van to crash. But when the Orphnoch bounty hunter Aoki appears, Takumi uses the Gear to kill the Ox Ophenoch with Keitaro witnessing the fight, later stealing the Faiz Gear to use it to save people.

However he also can't transform, the incident results with Orphnoch bounty hunter Akai taking the Faiz Gear and using it. The Autovajin cancels the Faiz Gear so Takumi can reclaim it and kill the Cactus Orphnoch, deciding to keep the Faiz Gear and the Autovajin. Once Kusaka learns that it was Takumi who slaughtered the class of Ryuusei School, he meets with Takumi with the intent to kill him. Luckily, Yuji was able to save Takumi from being killed. Takumi then found and helped Mihara and Rina by transforming into Kamen Rider Delta and fought an Orphnoch attacking them. When he woke, he then decides that he would rather die than become Smart Brain's ally. He fights the Chief only to be beaten and somewhat saved by Yuji and Kusaka. He then finds out from Mari that he isn't the one who killed everyone on the night of the reunion, but the Dragon Orphnoch was responsible.

Soon after, he becomes Faiz again but this time with a new form: Blaster Form. Using this new power he manages to care off the Dragon Orphnoch. Mari asked him to come back, but refuses. He gives Mari the Faiz Gear and runs off. He then challenges the members of Lucky Clover to final battle where everything would be decided. After that, he finds that Sawada is still alive. He eventually learns from Sawada that the attack on the Ryuusei School Reunion was not a random attack, but a plan conducted by Smart Brain to try and artificially create Orphnoch. He also learned that most of the students were failed subjects and that only a handful survived, but only he himself became an Orphnoch. He passed out before he could tell Takumi anything else. Takumi takes Sawada to a safe location where Sawada learns why Mari can still believe in Takumi even though he's an Orphnoch before Sawada knocks him out and takes his place fighting the three members of Lucky Clover as the battle Takumi challenged to Lucky Clover. After witnessing Sawada's death, Takumi decides to fight alongside Kaixa and Delta not as an Orphnoch, but as Faiz.

After Yuji Kiba becomes president, after the first one was fired and defeated by Faiz, Kaixa, and Delta, and the death of Masato Kusaka, Takumi learns that the Orphnochs are destined to die unless the Orphnoch King is awakened. But if the King awakens, then all of humanity will die. He learns that the Orphnoch King is Teruo Suzuki and tries to destroy him to save humanity, but Kaido tried to stop him and Takumi failed. He tried again but this time Yuji stopped him and took his body back to Smart Brain for examination. He was saved by the combined efforts of Keitaro, Mari, Kaido, Mihara, and Rina before being confronted by Yuji again. Both he and Yuji then have one last battle that involved their powers as Faiz and Kaixa and Orphnochs. Takumi is able to claim victory as he spares Yuji's life because he said that he is "human". With a renewed sense of living, Yuji agrees to help Takumi and Mihara take down the King using the power of the Gears. The fight doesn't go so well when the Kaixa Gear is destroyed and it slowly destroys Yuji. But before he died, Faiz managed to land a hit on the King, destroying him and Yuji. During the epilogue, it's revealed that Takumi now has a dream: To make everyone in the world happy.

Axel Form is a form where Faiz can now move at the speed of sound for usually 10 seconds, his physical attacks also becomes 1.5 times stronger and he can perform a new variety of his regular finishing techniques. This ability was used mainly by Takumi, the suit's predominant user, though Yuji used it once when he took over temporarily as Faiz. Blaster Form is the most powerful form of the Faiz gear, the amount of Photon Blood that the Faiz Gear produces increases to the extreme where it overflows from the Photon Streams and spread itself over the Sol Foam and the Sol Metal, changing their color to red.
