Old Enemy
Time passed as Shiro created several holograms of herself to assist the three spirits in training with the specialised mechs.
With Shiina only needing two days, Shiro immediately had her practice with her specialised mech once the tutorial was over. She would be sent on missions outside of Asharia such as clearing out a high levelled monster nest or scouting without being discovered so that her proficiency with the mech would increase.
With a tiny Shiro by her side judging her, Shiina didn't dare slack and her progress was amazing as expected.
As for Oran and Akhess, they were less fortunate as everyday of training made them want to just run away.
Shiina was allowed to 'slowly' get used to a standard mech before using specialised mechs but these two were thrust into the deep end immediately. But since they were given a week deadline, completing the task was possible as long as Shiro cut down on their break times a little.
