Kai's party had an expedition on the sixth floor just like usual happened every day. Alexa was giving more pay attention to how she should inflict more damage on the monster, at the same time, she was trying to predict the monster's next moments since it was the best way to kill them.
On the other hand, Amelia was pursuing herself to become a more reliable mage like the famous adventurers she knew. In her mind, if she would have a chance to improve herself on this train, she will become useful to his brother Kai.
Yes, Kai was not expecting any repay for those people he helped right now. Yet, they were the ones who decided it so it can't be helped.
In the middle of the night, Kai and Isabella met again in the Circle. Of course, the exact plan was to torture Kain until he wished for his death.
