After some persuading, Minato insisted on having an arm transplanted. Kushina had no choice but to focus intently on sealing a White Zetsu Clone into him.
It didn't take long for Kushina to use the Eight Trigrams Seal to seal the White Zetsu Clone onto Minato's severed arm.
The Eight Trigrams Seal was made up of two Four Symbols Seals. It also had a Seal Lock, which allowed the seal's tightness to be adjusted freely.
A single Four Symbols Seal would have been more than enough for a little nobody like a White Zetsu Clone. But because Kushina loved Minato, she wanted to give her beloved the very best seal.
"All right, Minato. The White Zetsu Clone is sealed inside you now. I'll give you the key, so you can control the seal yourself."

The two needed time to form a bond, like a romance full of conflict.
The Jinchuriki had to try to tame the unruly Tailed Beast.
