Kei Tachikawa leads the Tachikawa Unit as its A-class commander and stands as the franchise's top-ranked attacker. He's known for his arrogant streak and enjoys needling Miwa, which understandably gets on Miwa's nerves—especially since Kei and Jin share a similar outlook and sense of humor that just doesn't land well with him. Off the battlefield though, Kei's pretty likable. He's got that joking, laid-back side that mirrors Jin's personality, even if it doesn't always win him points with everyone.
