Yoriichi and Michikatsu Tsugikuni were twin brothers. Had dark black hair with red tips. A mark on the left side of their forehead. Red eyes and had similar styles although Yoriichi liked red and Michikatsu liked purple.

The twins were in their senior year of high School and Michikatsu was dating a junior, Douma. Yoriichi had never liked Douma one bit and always tried to break her and his brother up with no luck. When the two finally graduated, Michikatsu was still happy he got to see douma while Yoriichi prayed that college would keep them apart. Yoriichi conducted an evil plan to convince Douma to be away and break them up.

Yoriichi invited his brother to come to s college party which Michikatsu kept refusing to because he wanted to continue talking with Douma and Yoriichi hung up on her and dragged his brother to the party anyways.

Michikatsu kept checking his phone, wanting to continue talking with his girlfriend but she wasn't responding— guessing she went to work on homework as since she just became a senior when he started college. Yoriichi went up to Michikatsu and handed him a drink which he refused but Yoriichi kept insisting he take it so he did. Michikatsu forced a fake smile, just wanting to talk to Douma back at home. Yoriichi brought one of his female friends and when he was about to take a photo of them, accidentally taking a live photo and the girl kissed Michikatsu 's cheek which he pulled back from so fast, disgusted and pissed off that a girl would do that when Yoriichi clearly knew he had a girlfriend. Yoriichi sent the photo to Douma to break her heart and finish the relationship she has with Michikatsu. He knew she would be extremely hurt because the Prom was coming up and Douma had already bought a gorgeous pastel pink princess dress with matching ties and accessories for Michikatsu. Michikatsu called Douma and she immediately started telling him that they were done, that Yoriichi sent her that picture and Michikatsu was so confused and hurt that she wouldn't hear him out on what actually happened. Douma was in bed, still crying and it was already prom night which she didn't want to attend because it would hurt her as she wanted to go with her boyfriend but now it is painful to bring it up. Michikatsu had called Douma so many times but nothing so he ended up calling her mom to see if he could come over and she let him. Michikatsu came over and went into Douma 's room to explain. She was still hurt and crying. Michikatsu was explaining hard, tears falling down his face. Douma mentioned how some girl got cheated on and found out when her boyfriend accidentally sent a live photo of another girl in his bed. Michikatsu then realized something, asking for Douma's phone then checked the photo. It was a live photo, the girl kissing his cheek and Michikatsu immediately pushing her away with an annoyed expression. Douma apologizes for not knowing and he accepts it. The two end up going to Douma's prom together with her posting a picture of them in the outfits and typing 'Prom night with my awesome bf!' as the caption. They went to have a great time and Yoriichi saw the picture, annoyed that his plan didn't work and went to call Michikatsu to ask how the hell he was able to have Douma trust him again after the 'cheating.'
