Makoto Asada is a supporting character who appears in the Cardfight!! Vanguard G series, specifically in the seasons G: Next and G: Z. He is a member of Team New Nippon, a team that plays a notable role in the U20 Championship storyline. Physically, he is a fair-skinned boy with short teal hair and purple eyes. His typical attire consists of grey slacks, a blue-green button-up shirt with light blue trim over a white collared undershirt, and black shoes.

As a cardfighter, Makoto Asada uses a Murakumo deck built around the Yasuie series. His fighting style reflects a calm and collected demeanor, and his strength as a player is said to materialize from the deep friendship he holds in his heart. He supports his teammates in a cool, composed manner, which underscores his role as a reliable member of Team New Nippon. His primary rival within the U20 competition is Kazuma Shouji, who actively undermines and struggles against him during matches.

Beyond these details, little is documented about his personal background, his motivations beyond team loyalty and competition, or any significant character development across the series. His relationships are largely confined to his teammates and his rivalry with Kazuma Shouji. No specific unique abilities or special techniques outside of his Murakumo deck are noted in available reliable sources.
