Shouichi Tsugami

For the alternate version of Kamen Rider Agito from Decade, see Shouichi Ashikawa.

Shouichi Tsugami (津上 翔一, Tsugami Shōichi) is the main character of the series.

History
He is a young man with no memory of his past and is living with the Misugi family. A generous, simple, all around nice guy, Shōichi's ideal life is to just work in his garden and please his foster family. He had a funny habit by addressing someone that he didn't know as Koungouji-san. He fights as Agito due to the Unknown being somewhat tied to his forgotten past.

His real name was Tetsuya Sawaki (沢木 哲也, Sawaki Tetsuya), the younger brother of Yukina Sawaki whom fell in love with the real Shōichi Tsugami. Yukina and Tsugami participated in a research study conducted by Prof. Nobuyuki Kazaya (Mana's father) on human paranormal abilities. Yukina found herself as the subject for the study as she possessed such capabilities. The two pursued a romantic relationship, but as her powers matured (showing evidence of her awakening as an Agito), she committed suicide. After hearing of his sister's suicide, Tetsuya attempted to contact Tsugami, with his search leading him aboard the Akatsuki (a ferry).

Unaware at the time that Tsugami himself had committed suicide, Tetsuya searched for him to no avail. Instead, he discovers the lifeless body of a young man, who eventually reveals himself as the Overlord of Light. The deity, sensing his brother had sent one of his emissaries to the boat, awakened Tetsuya as the second Agito before vanishing, just as the El of Water arrives. The El assaults Tetsuya, sensing his churning power, but just as the final blow was about to be dealt, Tetsuya transformed into Agito for the first time. The ensuing battle ended with Tetsuya being tossed overboard, where he was labeled "lost-at-sea" by the authorities. But, Tetsuya had survived and washed ashore but was left with amnesia. He would be found by a trio of schoolgirls and brought to the hospital to be cared for by Dr. Higashi Kunieda, and going by the name on letter in his possession, he assumed the alias of Shōichi Tsugami, who had died at the time.

Now Shōichi, Tetsuya would be placed under Dr. Kunieda's care for some time until he was transferred to Misugi. There he would live a quiet, somewhat normal life, with no cares of whether he'll remember his past or not. That was until the presence of the Jaguar Lord Panthras Letus re-awakened him as Agito. However, Shōichi was in a feral state of mind at the time, attacking G3 only to regain himself before he could land the deathblow. The incident left Shouchi fearful about the changes, but the fact he has a place he belonged to gave him the courage to use his new found power to protect those he befriended, with Mana the only one in the Misugi household to know of Shōichi's transformation. By accident, Shōichi cross paths with Tomoko Miura, one of the Akatsuki's surving members who later called him to meet her the next day at East Park for the answers he's looking for. However, due to Tomoko being murdered, Shōichi never meet her, resulting in with him being arrested on the charge of her murder until he was eventually cleared when Mana pointed Hikawa to the actual culprit, the Overlord.

On the day of Mana's birthday, Shōichi attempts to protect her from the Scorpion Lord Leiurus Acutia, only to be poisoned as a result. Fortunately, he was cured in time and eventually kills the Unknown. Later on, by chance, Shōichi momentarily recovers his memory after his fall into the reservoir during his battle with Gills, recovering a large portion of his memories and facing Tetsuya. The recovered memories were enough for Shōichi to access his Trinity Form but eventually his amnesia returned before he could make any progress. After countless battles, Shōichi would come face-to-face once again with the El of the Water, who stalked him at every juncture. The anxiety and fear of confronting his 'killer' ultimately broke his fighting spirit. But with the help of Mana, Shōichi rekindled his bravery and assumed the ferocious Burning Form and defeat the El.

Coping with his constantly evolving powers proved difficult at first. When his old caretaker, Dr. Kunieda, came to pay a visit Shōichi transformed into Agito Burning Form, losing his composure in a fit of rage, and inadvertently attacks Dr. Kunieda. The shame of the accident weighed heavy on Shōichi's soul as he fell into self-loathing, sulking over his actions. But thanks to Dr. Kunieda's tough love, he was able to cast his shame aside and arise to embrace his existence as an Agito. Dr. Kunieda's words served as a reminder to stay true to himself and the value of his life, which gave him the clarity of mind and heart to achieve Shining Form and defeat the Beetle Lord. This new conviction and form would prove essential when the El of the Water returns more powerful than before. Its presence enabled Shōichi to recover his memory and, in their final encounter, finally destroy his nemesis once and for all.

After recovering his memory and tells his past and real name to his foster family, Shōichi decide to stay with them and continue to live as Shōichi Tsugami. Everything went smoothly, until Mana try to asking Shōichi about her dead father, because Shōichi is the last person that her father met before he died. These series of events finally reveal a shocking truth, that Shōichi's sister is the one that killed Mana's father, Nobuyuki Kazaya. Though by accident, because she could not control the Agito power. This is leading to Shōichi begins to doubt the Agito power inside him and making him believe that he should be amnesiac forever. Things getting worst when Mana finally begins to hates him, this is causing Shōichi didn't want the Agito power anymore and willingly relinquished it to the Overlord.

Despite this however, Shōichi couldn't let the Lords continue their killing as Ericius Liquor begins to targeting Mana. Shōichi then accidentally getting hit by the Lord quill, but successfully saved by Kino before the wound kills him. Sh ichi and the gang arrived at the scene to be confronted by the Overlord who choosing to kill all of them. Mana who have learning the truth from Ryo, encourages Shōichi to once again fight as Agito, as he runs to the Overlord and able to land a punch on him through Hikawa's aid. Shōichi, along with Ryo and Kino, finally regains their respective power. And together they defeat the Hedgehog Lord.

Sometime after, he bumps into his old cooking teacher, Kuramoto, who offered a job to work in his restaurant. With supernatural murders at a low, Shōichi takes the job under his mentor. While working there, he meets Kana, a distant reclusive young lady who dreams of succeeding as a chef in honor of her father. But Kana begins showing signs of becoming an Agito herself. Unable to comprehend the change, she tries to commit suicide, much like Shōichi's sister. History begins to repeat itself, with Shōichi holding onto Kana for dear life. But just as he is about to give up, Tetsuya Sawaki, the real Shōichi Tsugami and Yukina's resurrected former lover, comes to his aid and helps Shōichi pull Kana to safety; while simultaneously redeeming himself for not saving Yukina from the same fate long ago. The group then shortly confronted by the El of Earth, Shōichi then transforms in front of Kana and pleads he will fight for himself, for human and for the Agito's.

He is then overwhelmed by the combine effort of strengthened El of Earth and El of Wind, by the time both Hikawa and Ryo appears to aid him, Shōichi assumes Agito Shining Form one last time and steps into final battle to reclaim back humanity's fate from the Overlord.

After encountering Shocker soldiers and a kaijin, he is confused as to why they refer to him as a "Kamen Rider."

Storm Halberd
The Storm Halberd (ストー ハルバード, Sutōmu Harubādo) is a double-bladed pole arm that serves as Agito‘s primary means of attack while in Storm Form. When its blades are unfolded, the Storm Halberd can stir up gale-force winds powerful enough to halt most adversaries with a barrier of wind.

Flame Saber
The Flame Saber (フレイ セイバー, Fureimu Seibā) is the signature weapon of the Flame Form, a sword of unparalleled sharpness. Its lethality is further increased when all 6 "Flame Horns" are opened; a Saber Slash while in this state would literally reduce an adversary to ashes.

Agito can execute similar boosted attacks in Storm and Flame Forms with Halberd Brake and Saber Brake.
