*At the Kai residence* 
Yamato: Valiente! 
Hina: Bro that's the 12th time you beat me. Today! Ever since dad came home, and you lost to Ai you've been more angry.
Yamato: That good for nothing could just stay at Europe, and I will not lose to Ai again! 
Hina: Why do you hate dad so much?!
Yamato: Hinata he left mother to raise me, and you and you're defending him?!
Hina: He had to! That's something no one could control, and if he had a choice to stay he would! 
Yamato: Then why didn't he take it then huh Hinata?! 
*while Hina, and Yamato argue Misaki, and Kai were listening in from the other room.* 
Misaki: Yamato.
Kai: It's my fault he's this angry.
Misaki: Toshiki no it wasn't! 
Kai: But he had a point. I did leave for you to raise him, and Hinata. 
Misaki: Toshiki you had no choice. Everyone but Yamato understood, and we were waiting for you to come home.
Kai: But Yamato. 
Misaki: Don't worry Toshiki. 
Kai: But he's our son Misaki. 
Misaki: He'll find a way to forgive you Toshiki. 
Kai: I hope. 
*the door bell rang.*
Kai: I'll get it. 
*Kai opens the door to see Ai, and Aichi.* 
Kai: Aichi, and Ai. I didn't honestly expect you. 
Ai: Hello Mr. Kai is Yamato around? I need to talk to him.
Kai: He's in the kitchen, but he seems really angry after I came home, and you beat him.
Ai: I know, but I want to help him. 
Kai: Just like your father. But Aichi why are you here?
Aichi: Well Kai I-
Misaki: I called him so he can talk to you.
Kai: Misaki? 
Misaki: I figured the kindest one in Q4, and your rival that is a father could help. 
Kai: Well come on in then. 
*Ai goes to the kitchen* 
Ai: Hello. 
Hina: Ai!? You're here? 
Ai: Yeah to talk to Yamato.
Yamato: What do you want Ai?! 
Ai: Yamato I want you to join my team. I thought since you are the strongest fighter I know, and you seemed so angry I thought you joining my team can help you. 
Yamato: A team with you? That's a joke right? 
Hina: Bro he beat you twice you know. 
Yamato: Shut up Hinata. 
Hina: Maybe 3rd time's the charm. 
Ai: I'll fight you Yamato. If I win you join.
Yamato: And if I win you admit I'm stronger than you, and your victories were luck.
Ai: Deal.
Hina: I bet on Ai. 
Yamato: Shut up.
Hina: 😝 Never!
