Kusunoki Kayo's father, Kusunoki Rentaro also made a fuss with this. Himura Takata was busy stopping him.
Amira suddenly became quiet as she watched the fight. Alex kept exploiting Kayo's weakness one by one. Kayo noticed this and slowly improved her stance as she tried to block all of his attacks. Though her body became tattered, she persisted... she struggled to prevent his attack.
Every attack that Alex made by exploiting her weakness made her movement better. She fixed her flaws one by one under the constant booing from the audience. Alex ignored them completely.
The reason Alex did this was that she reminded him of his sister on Earth. Even though he didn't want to entangle with his memory in the past again, he still couldn't help but be like this.
