Warhammer 40K:Adeptus Custodes from Another World(EN version)

Princess Shiruu, along with her troops, escorted Dante and his entourage back to the palace. Allarach and Kyoshiro thoroughly observed the peaceful situation. Dante occasionally glanced around at the surroundings; Hamanaka had a design reminiscent of ancient Terra from the Dark Age through the Middle Ages. Dante noticed that some of the inhabitants looked a bit frightened by his imposing figure and unfamiliar weaponry. A few children offered flowers, which Dante accepted as a sign of their peaceful reception. Kyoshiro was puzzled by this behavior, but Allarach signaled him not to interfere. 


Soon, the group arrived at a large city situated beneath a mountain. They proceeded to the palace, where they were greeted by the king and queen. All of the inhabitants had rabbit or hare ears. 


"Greetings, great leaders. We are from the Imperium of Mankind and wish to invite this world to become a part of the Imperium of Mankind," Dante said.
