Shingo Komoi is a main character in the Link Joker season of Cardfight!! Vanguard. He's best known for piloting a Murakumo deck centered around the Magatsu ride chain.
His introduction is pretty awkward—he gets caught hanging around Kourin in a way that reads as stalker-ish. Naoki immediately calls him out and threatens to throw down, but Shingo defuses the situation by challenging him to a cardfight instead. Turns out his real obsession isn't Kourin; it's Aichi. Shingo became a devoted Q4 fan after watching Aichi compete in the VF Circuit, and that hero worship drives a lot of his actions throughout the season.
