Aichi Sendou

Aichi Sendou is the central protagonist of Cardfight!! Vanguard and a gifted user of the Royal Paladin clan. His interest in Vanguard begins with the Blaster Blade card given to him by Toshiki Kai in Cardfight Vanguard.

Aichi Sendou's growth through Vanguard

He starts as timid and isolated, but cardfighting gives him confidence, friends, and a sense of purpose. Aichi's desire to stand beside Kai sometimes turns into unhealthy dependence, especially when the power of Psyqualia affects his judgment.

Blaster Blade, Psyqualia, and Team Q4

Aichi possesses strong tactical intuition and later awakens Psyqualia, an ability that lets him sense the flow of a fight. His relationships with Kai, Misaki Tokura, and Team Q4 drive his growth from an anxious beginner into a respected leader.
