Their training under Thalric was still ongoing. However, their training time was reduced to two days a week after the surge of undead attacks. But during that time, Ishii was able to get a glimpse of what he lacked the most.
Insight.
It wasn't that he needed to develop the ability to plan three steps ahead. What he lacked was the ability to read the present fast enough to ensure the best outcome.
Even then, his initial views on the matter were wrong. Because he was still looking at it through the perspective lens of a samurai code of conduct. Nothing was fair in war.
The dueling skills he prided himself on were also hindering him. Thalric made sure to beat that into him the first day of training without hesitation.
In their first bout, Thalric showed them just how strong he was, taking on all seven of them by himself while the adventurers under him tested the rest.
