In order to explain the concept of Shinkai, Tokimori Hazama compares it to Zekkai: where Zekkai concludes with erasing everything, Shinkai initializes everything. In other words, it creates a new world. Shinkai uses more power than would be possible for a normal human, but it will be possible if Yoshimori uses Chushinmaru Karasumori's power. This will enable him to create a world where the lord can be safely sealed. Yoshimori asks if it is really okay for him to use Chushinmaru's power, but Hazama responds that it would be troublesome if he didn't. He asks Yoshimori to create a nice castle, since Chushinmaru likes them.
