During the second week of training, Shiro started to show signs of achieving the lowest level of Mio's Absolute Defence. Even though she couldn't block everything, she could now find one or two gaps to counter during Mio and Koji's barrage of sword attacks.
In addition to this, thanks to Koji's training, it was now harder to divest Shiro of her sword and even if they did, she could summon a new one straight away. Rather than using all the copies of Athera straight away, she'll keep one just in case she's disarmed so that she could rearm herself quickly.
As for the one that was knocked away, she would unsummon it so that she could act as a spare. That way, she could always make sure that there is a sword in her hand.
There was a point that Mio brought up during their training which caused Shiro to wonder about the possibilities of her sword with her class and that was, can she change the structure of Athera.
