The suicide mission
Haruto made his first appearance after Koga had been defeated by Ionia and sent to prison, revealing that he had already been a prisoner for a long time as he had suspected the headmaster of Pallestra a while already. Haruto introduced himself and they escaped the prison, defeating the Beetle Brothers before reuniting with Yuna, Souma and Ryuho. They traveled together to save the mysterious girl Koga had met earlier. However, Micene follows them and in order to allow Yuna and Aria escape, Koga, Ryuho, Souma and Haruto stay behind to fend of the Gold Saint as long as they can. Despite all of Haruto's tricks and techniques, Haruto is easily defeated by Micene.
The Wind Core
As Koga and Yuna are inside the Wind Core, Haruto appears, telling Souma and Aria that the Core is guarded by a Silver Saint. Devising a plan to get inside, they arrive just to notice Koga defeating Fly completely, allowing Yuna to destroy the Wind Core.
The Earth Core
WIth Koga, Yuna and Souma going ahead, Haruto stays behind to check the place for traps, in which he both found out a trap had been set for them as well as finding the Earth Core, taking Aria with him to destroy it, chasing away Michelangelo at the same time, mocking him for running away instead of fighting, commenting that the Cloth probably was only for decoration, destroying the Earth Core with Aria.
The Water Core
Moving onward, Haruto, Koga and Yuna hurries to save Ryuho who is fighting Mirfaak. Although they have increased their Cosmo during their hard battles, Mirfaak turns them into stone, leaving Ryuho to fight the Silver Saint alone. After Ryuho has defeated Mirfaak and destroyed the Water Core, Haruto decides to leave the group for a while, with Ryuho following.
The Origins of a Ninja
As Haruto reminisce about his past when Yoshitomi was killed by Tokisada, he later meets Ryuho before a group of ninjas ambush them, forcing them to fight. As Ryuho is grabbed by a scorpion, Haruto states that he is a ninja but also a Saint fighting for Athena, freeing Ryuho and having maked his decision, his father tells him to walk his own path.
The Tower of Babel
Haruto and Ryuho joined the other Bronze Saints in order to rescue Aria from Eden, but the two had already left for the Thunder Ruins, making that their next destination.
The Thunder Ruins
Arriving at the Thunder Ruins, Haruto stayed behind to fight the Silver Saint Bartschius, defeating her just before falling down to the Darkness Ruins along with the other Saints. He wakes up with Ryuho and Yuna, noticing a huge door which shows them their deepest memories.
Wolf vs Wolf
As Haruto sees his darkest memory of his brother scolding him for leaving, he is quickly attacked by Yoshitomi and is easily beaten to the ground. However, after a long battle, Haruto finally overcame his dark memory and reunited with the other Saints.
The death of a friend
As they reunited, Mars appeared and attacked Aria and the Bronze Saints. Determined to defend their friend, the Saints pressed on against Mars, until Mars finally killed Aria, leaving the Bronze Saints devastated at their friend's death. As she died, she transported the others away to safety.
The Twelve Temples Battle
After mourning Aria's death, the Bronze Saints made way up the staircase they had been teleported to. Arriving at the Aries Temple, they encountered Kiki who told them about Mars' plan to destroy the Earth and repaired their Cloths before they kept pressing on through the other Temples.
Arriving at the Taurus Temple, Haruto, Ryuho, Souma and Yuna fought Harbinger but they were all easily defeated, no matter what they attempted. In the end, the Gold Saint sent them all away, with only Koga remaining at the Taurus Temple.
Haruto and Souma are revealed to be on their way to the Leo Temple where they encounter Micene again. Still struggling to fight the Gold Saint, they eventually see through his attack and they disable it. However, Micene attacks with his strongest attack, aiming for Souma. Haruto, however, steps between and attacks Micene's technique directly, sacrificing himself and destroying his headpiece, while telling that they are Saints protecting each other, and others would pass where they would eventually fail. Seeing such a brave act of courage and friendship, Micene allowed the two Bronze Saints to pass through.
Arriving at the Virgo Temple, Souma and Haruto were greeted by Fudo. In spite of not wearing a Cloth, the two Bronze Saints were easily defeated by the Gold Saint and they were almost killed. However, Koga, Ryuho and Yuna arrived just in time to save them both from death, but they were still defeated, in spite of all five attacking Fudo. As he donned his own Gold Cloth and was about to exterminate the Bronze Saints, Eden stepped between and sent the others ahead.
On their way to the Libra Temple, the Bronze Saints were intercepted by Tokisada, whom Haruto recognised as his brother's murderer. Before the Gold Saint could finish the battle against them, the Libra Weapons teleported the Bronze Saints and Tokisada to the Libra Temple where Genbu would take over the fight. However, not accepting defeat, Tokisada attempted to take the Bronze Saints with him to the End of Time, but he only managed to suck in Haruto and Ryuho.
End of Time
At the End of Time, Ryuho and Haruto resumed their fight against Tokisada who had recovered from his battle against Genbu and easily overpowered them once again. As Haruto and Ryuho tried to burn their Cosmo together to defeat Tokisada, they were still unable to defeat the Gold Saint as he was to strong for them both to handle, due to his control over time.
After being knocked around and being mocked for his brother being disappointed that he would now kill another wolf, Haruto finally awoke his 7th sense and seemingly killed Tokisada, avenging his brother.
Joining the other Bronze Saints to the final Temple, he, Ryuho and Souma were forced to fight the Heavenly Kings in which his right arm bracer received moderate damage. In the end, the three Bronze Saints defeated the Heavenly Kings before collapsing.
As the Bronze Saints arrived at the planet Mars, he and the other Bronze Saints fought effortlessly to defend Athena from Koga who was now possessed by Abzu, receiving Darkness Wounds from the God of Darkness. In the end, he and the other Bronze Saints gave their Cosmo to Koga, allowing him to defeat Abzu once and for all.
The howl of the new Wolf
A year after the defeat of Abzu, Haruto has joined a rock 'n' roll band, abandoning his duty as a Saint, since rock had more meaning to him. During the year that passed, Haruto also overcame Yoshitomi's death completely. However, as Koga and Subaru was attacked and almost killed by Hati and his concert was ruined, Haruto joined his fellow Saints and donned his new Wolf Cloth, returning to his duty as a Saint.
After Genbu's death and the arrival of Seiya and Athena, the Saints prepared themselves to assault Pallasvelda. On their way to Palaestra, they were ambushed by Greip. Before he could attack them, Haruto stepped in and told the others to move ahead. However, Subaru insisted on helping but fell down after being attacked by the Pallasite, resulting in Haruto jumping after. Later, as they talked, Greip attacked again, this time along with his brother Greip. The two struggled against the two Pallasites, with Subaru being greatly wounded. Later, as they attack again, Haruto and Subaru finally manages to defeat them, reuniting with the other Saints before the gate of Pallasvelda, breaking in and starting the battle against the Pallasites.
As Koga returns with a young girl, she suddenly starts to burn her Cosmo, revealing to the shocked Bronze Saints and Subaru that she is in fact Pallas, the Goddess they have come to kill. However, Titan appears and prevents them from moving, almost killing Koga before Seiya arrives.
The rankless Pallasite
A the second day of the battle begins, Haruto, Ryuho, Koga and Subaru encounter Mira. Thinking he is an easy opponent since he has no Chronotector, they underestimate him and battle him. However, he easily destroys Koga's right shoulderplate, Ryuho's shield, most of Subaru's chestpiece, and almost Haruto's Cloth completely, before they finally manage to hit him. However, before the Pallasite can equip his Chronotector and fight for real, Europa appears, before the two of them leave the scene.
Celeris, the Equuleus Bronze Saint
While fighting, the Saints encounter Celeris, who is defending a group of villagers from the Pallasites and prefers to defend them rather than leaving them behind in order to follow Athena's orders of leading the Saints as he is closest to the castle. When Thebe attacks, Koga, Ryuho and Haruto deal with the footsoldiers, while Eden deals with Thebe.
In desperate need to repair their Cloths, the Bronze Saints make way to have their Cloths repaired by Kiki. On their way, they are attacked by Cyllene and Greip. However, Subaru appears, equips the Equuleus Cloth and defeats them both at once. They later encounter Kiki, and the Gold Saint repairs their Cloths before dealing with Dione.
As the Saints manage to break the Gate of Time, they find the path splitting into four different paths. Having no time to lose, the Saints split up into groups of four.
Teaming up with Subaru, Eden and Hyoga, the four Bronze Saints make way for Niflheim where Hyoga would berate Subaru for not staying cool enough in battle. After sending them ahead, Haruto sense a familiar Cosmo, and violently shoves the doors up.
Time vs Ice
As suspected, the Cosmo indeed belonged to Tokisada who was still alive and the current Class 2-Pallasite. Still hating Haruto for losing during the Twelve Temples Battle, Tokisada attacks Haruto in rage, swearing to get his revenge, also revealing that he was given a second chance after Haruto almost killed him. Before Tokisada could kill them, Subaru attacked Tokisada with a greater Cosmo, wounding the former Gold Saint for the first time, shocking him. Before he could attack Subaru, Hyoga appeared and thus the two former Aquarius Gold Saints faced each other, with Hyoga triumphing in the end by trapping Tokisada in the Freezing Coffin.
As they kept running in a hall that seemed endless, Paradox and Integra used the Another Dimension, allowing the other groups to rendezvous at the battlefield between the Gold Saints and Gallia, with Hyoga and Shun heading after Europa.
With Athena and the Gold Saints moving onward to Pallas, Haruto remains with the other Bronze Saints to fight Gallia, unsuccessful at dealing damage to the Class 1-Pallasite and she easily defeats them. However, after Subaru's sudden explosion of Cosmo, Haruto joins the others and together, they awake the legendary Omega and finally defeats Gallia.
As the Bronze Saints arrive at the battlefield where Shiryu, Fudo and Kiki sacrificed themselves, they encounter Hyperion, who is still alive but without his sword as the three Gold Saints were able to destroy it. As the battle begins, Hyperion easily defeats them in spite of them drawing forth the Omega they used to defeat Gallia. However, Subaru stands up and attacks Hyperion, drawing upon his massive Cosmo once more, finally sending Hyperion falling. But he quickly deals with Subaru and steals his time, before turning his attention to the remaining Bronze Saints. Seeing Subaru sacrifice his own life for his friends, the other Bronze Saints desperately attack Hyperion, but end up having their Cloths totally destroyed. However, refusing to give up, they once more stand up and burn their Cosmo, horrifying Hyperion who in panick attacks them with his full might, with no effect as they keep burning their Cosmo. As Hyperion moves in to destroy Subaru, the Bronze Saints stand between, gathering their Cosmo into one and reaching the Macro Cosmo, finally awakening their true Omega Cosmo. As their Cloths cover them once more in a more powerful state than before, Hyperion desperately tries to annihilate them, but they prove to be too strong for him and they easily damage his Chronotector. As Hyperion tries to take them down in a suicidal attack, Eden destroys his Chronotector completely before Subaru, who managed to return, finally defeats Hyperion by sending him flying up where he explodes from the impact of his own suicide attack, granting the Bronze Saints victory.

Haruto wears the new version of the Wolf Cloth that was prievously worn by Nachi. It covers most of his arms, fully covers his chest, fur has been added to the waist and the neck, and he has emerald at his knees and chest. When not wearing the Cloth, he wears the Clothstone as an earring on his left ear.
After Kiki repaired the Bronze Saints' Cloths, Haruto recieved more red linings on his arms as well as the ability to extend his claws whenever he burned his Cosmo to reach a Gold Saint.

As Haruto joined his friends in the battle against Hyperion, the Pallasite easily destroyed their Cloths, leaving them defenseless. However, not wanting to give up hope of saving Subaru, the Bronze Saints once more stood up, attained the Macro Cosmo, and received the power of the Omega Cloths. Haruto's Omega Cloth covers almost 100% of his body, sprouting wings from the back. The Cloth has received golden inlays as well as the symbol of a wolf covering his chest. Like Ryuho, the chestpiece covers only the upper part of his chest, leaving the lower part of his upper body exposed. His tiara has received great differences from the previous, as it now has a mix of green, gold and grey.
- Haruto was thought to be the last main character introduced to the Saint Seiya Omega cast, as he also fitted in as the lone wolf who stayed calm in battle and due to his sudden apperances. However, another Bronze Saint was instead chosen for that part, Eden.
- When Haruto does not wear his Cloth, he has glasses. But when he equips his Cloth, his glasses are removed and the hair always goes over his right eye.
- Haruto is the Bronze Saint who has the most techniques among the main characters, similar to Shun who had dozens of attacks with his chains.
- Yoshitomi is not Haruto's biological brother, but Haruto looked so greatly up to him that he considered him like a brother. During Tokisada and Haruto's second fight, Haruto no longer fought to kill him and avenge his brother, but to fulfill his duty as a Saint.
- Haruto is the fifth Bronze Saint to reach his 7th sense.
