My OT3 (which I found just last night) is Keita/Jungo/Airi from Devil Survivor 2. The sweet Jungo would probably be up, while Keita would be down. As for Airi - she'd see herself as beauty, but she's more like charm. They are a charmed Lambda baryon, which apperantoy carries a positive charge. Almost like it shows how much positivity they are giving each other (even if two tsunderes try to hide it).
Then there's one OTP - Archer/Lancer from Fate/Stay. With his personality, how could Archer be anything but absolute antiup and Lancer is pretty much pure charm. So they are a D meson.
