Teneo de Tauro

Teneo, like Celintha and Salo, lost his parents in an unspecified major disaster, and the three ended up living on the streets until they were found by Rasgado, who took them into his home along with several other children in similar circumstances. When the Holy War began, Rasgado changed his name to Aldebaran and abandoned his peaceful life, forcing him to leave his beloved children. Teneo, Celintha, and Salo decided to become Knight apprentices, disciples of Rasgado, so they could continue living with him. Teneo greatly values and praises Rasgado's sacrifice, being the only one of the three disciples who doesn't continue calling him Rasgado when he's not around. When the Holy War enters its most active phase, after Hades' complete awakening, Teneo continues training as an apprentice and witnesses his master's battle against Kagaho of Bennu, a Spectre of Hades, from which he emerges victorious but wounded. During a training session with Tenma of Pegasus, they are attacked by the Spectres Wimber of Bat and Cube of Dullahan. Wimber uses his Nightmare Sonar technique to put everyone to sleep, and when they wake up they discover that Aldebaran has been murdered. While paying his respects to Rasgado at his grave, alongside Celintha, Teneo discovers that his companion is abandoning her training, not before telling Teneo that one day he will inherit the mantle of the Taurus Saint and the name of Rasgado, as a legacy from his master. Tenma is seen in the distance observing them in sad silence. After that, Teneo was in the Sanctuary army and participated in the assault on the Cathedral of Hades, in which many soldiers were massacred. He escapes by a narrow margin, unlike Saro who loses his life.

After the defeat of Hades and the loss of most of Athena's forces, as well as the sacrifice of Tenma and Sasha, Shion appears, now as Patriarch, who assures that all is not lost. There, Teneo is shown, ready to continue fighting for the Sanctuary, representing the new generation of Saints who will protect the peace and justice that Athena bequeathed in life, determined to become the new Golden Saint of Taurus. Six years after the Holy War, Teneo became the Golden Saint of Taurus to continue the reconstruction of the Sanctuary alongside Shion of Aries, now the Pope. With the help of the Great Horn, he saves a group of civilians, including Agasha and Selinsa, from a landslide. Both are former classmates, and their reunion leads to Shion telling him the mission to go to Sicily, where the seal on Typhon, now imprisoned under Mount Etna, may not have been properly placed 14 years ago. Therefore, it is vital to prevent the giant's resurgence, especially considering the small number of troops available at the Sanctuary at the time. The following morning, he reunites with Selinsa at the cemetery. He gathers at the tombs of Aldebaran of Taurus and Saro, as they used to do. She tells him that the man who had given him the same mission fourteen years earlier was none other than his deceased master. Fourteen years after the end of the Holy War, Yōma of Mephistopheles, the reincarnation of the god Kairos, breaks Athena's seal and attacks the Sanctuary to continue his plan of creating a war between the gods. Upon arrival, he confronts Teneo, who protects the young Saints and apprentices from the god's attacks, as they cannot defend themselves because he has stopped time in the Sanctuary.

Kairos belittles the Taurus Saint as a mere human, but the Saint manages to hit the god twice with his Pleiades Nova and Titan's Nova. However, he barely wounds the god, who retaliates against Teneo with strong blows and attacks on the paralyzed youths, which Teneo manages to stop. The fight is interrupted when Kairos is transferred to the Temple of Athena by Shion. As the god of time, Kairos makes him regress in his fight against Shion, causing the Taurus Saint to disappear, as he returns to a pre-birth state. But after Kairos's destruction by the spirits of Tenma and Sasha, the effects of the time regression disappear, returning Teneo to his real age.

•Great Horn: This consists of a punch delivered at the speed of light, allowing him to strike from a distance thanks to the air pressure produced by exceeding the sound barrier. For someone unable to move at the speed of light, the movement of the fist is imperceptible. •Great Horn Tosshin: The Taurus Saint lunges at his opponent, striking him in the chest with his right hand at great speed. •Titan's Nova: Places his hand on the ground and sends a wave of cosmos that causes a gigantic earthquake, destroying the surrounding area. It seems to evoke the earth's energy from the ground, completely shattering the terrain to several meters deep, lifting rocks and making them levitate in the air before unleashing a rain of debris upon the opponent. The enemy first affected by the wave is dragged into the cataclysm and sinks into the abyss. •Bullring Spike: This consists of charging the opponent at high speed, breaking everything in its path, throwing oneself forward with bent arms, one more prominent than the other, and legs in a running position, against the opponent at high speed to strike them with great force. •Grand Knock: This is a technique that consists of striking the ground violently to create an expanding wave that stuns opponents. • Pleiades Nova: The user concentrates cosmos in their hand and raises it upwards, creating beams of energy that form spheres containing immense power. This power is unleashed at the opponent when the user throws with their right arm, capturing the opponent to unleash the energy spheres. To increase the technique's power, the user raises both arms and joins them with the palms of their hands, maximizing the technique's power. •Titan's Break: This technique has a destructive power that can lift the earth in large rocks; it is used by Hasgard of Taurus who concentrates the cosmos in his hand, and then grips the ground in order to lift and bury his opponent.
