No, not regret. Sometimes, scientific endeavours will have mediocre results. It is simply part of the process.

In the end, we were proactive in all aspects. We gathered connections to others, our wins were plentiful, and our disagreements between our own were quite minor.

Because of our hard work as Yatagarasu, if we can survive this last trial, I will be able to grasp everything I desire. Because of your work as the leader of the resistance, you will be able to name this day vengeance.

So, there is no regret. I will give you some of my respect, instead.
