Aichi Sendou is the titular main protagonist of Cardfight!! Vanguard. He is a somewhat shy and timid young man who wishes to be a Vanguard Fighter, but has never had the chance to have a real fight until his second encounter with Toshiki Kai. When starting to play Vanguard, he believes more in himself, becoming a powerful Vanguard Fighter.
Story[]
A shy, nervous boy lacking in confidence, Aichi is the protagonist. When he was younger, Toshiki Kai gave him the rare card, Blaster Blade, which Aichi refers to as his 'avatar'. Through playing Vanguard and developing his skills, Aichi gains friends and becomes a more confident person, as well as unlocking the power of Psyqualia.
However, this power corrupts him, causing him to become cold and arrogant, and with Ren's coercion, Aichi abandons his trusted Royal Paladins in favour of a Shadow Paladin Deck. After a merciless winning streak he is finally saved from his insanity by Kai, who makes Aichi realise the folly of relying on the precognitive abilities of Psyqualia instead of his own inner strength and courage. Though Aichi switches back to his Royal Paladin deck, he cannot deny the part of himself that lusts after the Psyqualia power. He eventually accepts both desires- to use and reject Psyqualia- as equal parts of himself, manifesting in the Majesty Lord Blaster card.
In the second season, Aichi's Royal Paladins are sealed away due to Takuto Tatsunagi's Psyqualia and replaced by a Gold Paladin deck. For unknown reasons, Aichi is the only one aware of the alterations.
In Link Joker, Aichi is enrolled at Miyaji High School and forms a Cardfight Club alongside Kourin.
In "Legion Mate", Aichi is missing and nobody except Kai seems to remember him. When he finally reappears, he tells Kai and the others that he does not want them to chase after him, and that they should forget him. Turns out that after the fight with Void Agent Takuto, the void agent planted Link Joker's seed inside of him and is gradually growing stronger until it can take over him. In order to prevent another Link Joker invasion on earth, he willingly seal himself away and chose the Quartre Knights to protect him.
Physical Appearance[]
Aichi is a boy with long blue hair with a right hair bang which is his signature style. He is first seen in his Hitsue Middle School uniform which is mostly all gray with white linings along with a red sweater under it. His civilian clothes varies with the change in season particularly wearing a short green jacket with a red sweater under it for cold seasons while sporting a white double sleeved shirt for warm seasons. He is quite particularly short compared to other characters of the same grade.
By the start of the second season, he still wears his middle school uniform but he is mostly seen in his civilian clothes by the time of the VF Circuit which is a white jacket with a red sweater beneath it.
Personality[]
Introduced as someone who in the beginning was timid and shy. Aichi gradually gains the confidence in himself and his deck in order to fight against the best Vanguard Players and in turn meets new friends and allies along with new rivals. During the fateful encounter with Kai, who was still a friendly teenager, he gave him the card Blaster Blade, telling him to imagine himself big and strong, like the royal knight depicted on the card. Aichi couldn't picture himself any stronger at that moment, but the card gave him courage. He constructed a deck in the hopes of finding Kai and having a cardfight with him, but shortly after their encounter, Kai had apparently moved away. He eventually transferred to a different school after his mom got upset over the constant bullying. Aichi lives with his mother and little sister, Emi. It is shown that Aichi isn't interested in school that much and his sister always woke him up, though this behaviour disappears after he starts playing Cardfight!! Vanguard.
Abilities[]
Aichi uses a Royal Paladin Deck. His strongest cards are Blaster Blade, Alfred "The King of Knights," Soul Saver Dragon, and Majesty Lord Blaster. In his final confrontation with Ren, Aichi adjusts his deck so that Blaster Dark is mixed in with his Royal Paladins so that he could use Majesty Lord Blaster's abilities to the fullest.
In season 2, Aichi's deck changes into Gold Paladin clan, with his Ace card being Incandescent Lion, Blond Ezel from Kourin. Aichi now puts in more effort to superior calling units from the deck, using the Blade Feather Valkyrie / Flash Edge Valkyrie combination, as well as Nimue and Viviane, and units that can activate their skills upon being called from the Deck.
In season 3, Aichi has decided to use the Gold Paladin as his main deck. His deck consists of the Liberators cards which were originally Royal Paladin units along with his ace being his reborn avatar- Blaster Blade Liberator, though later Aichi modifies his deck around his new Crossbreak Ride card Liberator of Bonds, Gancelot Zenith in order to creating colossal units once cross ridden, and units like Viviane and Escrad will help Aichi fill up his field, so he can preserve his hand.
