Character Outline[]

Alto and his family listening to Ganelon's proposal
Alto was the eldest son of the Weinberg family, the most distinguished noble family of Britannia during the first half of 19th century. It was headed by Alto's father, an earl who served in the Imperial Court supporting domestic affairs. Before he knew it, a sense of duty to Britannia started to take root within a young Alto.
One day, his best friend, Ganelon, asked him if he could marry Alto's sister, which Alto took as the best news he had ever heard. In reality, Ganelon was a member of a rival noble family that had a history of being persecuted by the Weinbergs and sought to end their line. To achieve this, he got close to Alto and his sister, tying his name with theirs, and then assassinated First Prince Basilio, sending Britannia spiralling into chaos. Going on the run, he sold out his in-laws and his wife was executed by guillotine in his place. The rest of the family, Alto was told, were imprisoned in Temple Tower. Alto hunted down Ganelon, who revealed his true face and confessed with glee that he had been lying from the start for revenge, declaring that Alto would be the end of the Weinberg family before impale himself on Alto's sword.

Alto's meeting with Lorenzo
At some point, Lorenzo il Soresi approached Alto to retrieve Claire li Britannia from Japan, promising a successful job would see his family's honor restored and his family released from prison. During this meeting, Lorenzo also used his Geass on Alto to make him believe that Claire's mother is still alive.
Alto would do anything to protect his lady, Claire, and would punish anyone who hurts her. He uses a pair of long blades for weapons, but prefers to avoid unnecessary violence. He seems to have some sort of affiliation with Karasu Tengu, though the extent of which is unknown. He is an ancestor of Gino Weinberg, and bears a great resemblance of him.
Character History[]
He appears after the assault on Renya's village, collaborating with the Three Brothers. He watches on as Renya fights the Three Brothers until one of the brothers recklessly throws his weapon around the room, nearly hitting Claire. He then interferes and impales him with his own weapon. Afterward, he fights with Renya until he notices the aforementioned brother attempting to take Claire hostage. He tries to stop both him and Renya, but Renya kills the brother in a roundabout way, to his surprise.
Immediately after, the roof collapses and a mysterious individual with power over wind appears and Alto reveals that this person is a Knightmare. The Knightmare flees with Claire in hand and Alto gives chase alongside Renya.
However, along the way, they encounter a young woman running from a wild boar, which Renya kills. The woman reveals herself to be Futaba Sumeragi and announces her intention to kill Renya for assassinating Isshin Sumeragi. During the following battle, Alto interrogates a young man who was with Futaba who reveals himself to be Denshichirou and asks for their help in defeating a demon that can manipulate wind which he calls Karasu Tengu. Overhearing this, Futaba runs off in search of Karasu Tengu's power in order to use it to kill Renya.
Alto travels with Claire's group, promising they would find a new home in Britannia. In time, they are found by Barbaros and his men, who are actually there to kill her friends and retrieve Claire on their terms. Alto fights Barbaros away from the others, who reveals over the course of the fight that not only does he plan on crippling the princess, but that Alto would never regain his honor, as Barbaros had personally executed the rest of his family.
