Chichi was scolding Goku for going away without saying a word. Kushina saw that and asked Minato,
"Minato, you said this guy is extremely powerful. You even said he can easily defeat anyone in our world without even taking his second level power. But he's so afraid of that old lady. Who is she his mother?"
Chichi overheard that and she became angry. She walked towards Kushina and said,
"Who are you calling an old lady you grandma? I'm his wife, okay…?"
Kushina also became angry. She said,
"What did you just say you ugly. Treating your husband like a slave in front of others might be your culture, not mine. You should learn to keep your manners."
Chichi stepped forward and Goku caught her from behind. She said,
"I'll talk to my husband whichever way I like. You don't act like such a good woman to attract my husband."
Kushina smirked and said,
"Why would I try to attract a fool like your husband? My husband is a genius. And besides, your husband is so foolish to be enslaved by a woman like you."
Chichi rise up and said,
"Look who's talking, your husband looks more of a fool than mine just look at him."
Minato and Goku become embarrassed by hearing both their wife's calling them fool's. Chichi punched Goku's face and ran towards Kushina. They both started fighting like wild cats. Everyone started looking at them. That time Whis said,
"Oh…! Please my ladies. Why don't you guys make it a real fight? Let's see how powerful you both are. Just a friendly match. Don't have to push far."
Everyone looked at Whis. They wondered when he got there. Kushina and Chichi also stopped fighting but they were holding each other's hair.
Minato and Goku tried to seperate them but they were not letting go. They refused to let go at first then they did it simultaneously.
Everyone agreed to whis's idea. Minato tells Kushina to go easy on Chichi. Goku told the same to Chichi.
They decided to fight in the ring bulma created for training Trunks and Gotten
