Daichi is the oldest of the Tsukino family children. He is married with two kids and a dog. He came to Domino City, Japan to check on his family to see how they were doing. Well, he mainly came to check up on Jasmine because Diane called him to see if he can get Jasmine to change her mind about being with Kaiba. But what she didn’t tell him was why. He found out from Kaiba why Jasmine broke up with Yuugi and started going out with him. At first, he didn’t approve of Kaiba going out with his sister cause he hadn’t known him for as long as he’d known Yuugi. But he later got used to him and he had a feeling that he could trust Kaiba to take care of his sister and not hurt her the way Yuugi did.
