Whis stood in the middle of the ring as the proctor of the battle between Kushina and Chichi. Before Kushina entered the ring Minato said,
"Listen to me Kushina. I have two things to tell you. One, do not use the power of kurama and your inner chakra chains. Two, don't use too much strength on her but don't underestimate her."
Kushina nodded in agreement. She knew that Chichi is strong for a female fighter. That time Goku said,
"Chichi, don't overdo it. She's strong for sure but don't use your kaioken."
Chichi didn't say anything but she looked at Kushina.
After that they both got into the ring. They stared at each other. Whis said 'start'.
Kushina and Chichi didn't move. They stayed there staring at each other. The air became dense and heavy like they were gathering energy. Even Whis felt that situation. Then in a minute they both jumped forward. They started hitting and bitting each other. They pulled each other's hair and acted like housewives fighting over the same thing in a market.
Everyone was surprised to see their foolish act. Goku and Minato became so embarrassed and they both laughed like fool's. Picholo became angry and flew away.
Kirlin said,
"If this is the fight they were about to do then why did they come to the ring? They should have finished it over there."
Whis waited for a moment and he jumped in to stop them. He told them to fight like martial artists, not some old age women.
Both of them backed off. After a moment Whis started the match again. This time they started fighting seriously. Kushina and Chichi seemed to be evenly matched. Every move they made was equally powerful. Goku realized that Kushina is calculating Chichi's power level and applying an equal force.
Goku has already watched the fight between Kushina and the gold and silver brother's so he knows her strength. He felt regret for restricting the kaioken for Chichi…
