After clearing the carcasses of the Bison, Kai and the others flew back home. Rick was grinning the entire time, confusing everyone on board except Kai, who heard about how he wanted to boast about this to his daughter. He didn't say anything about it though.
On their way home.
"Say, Kai… What are you going to do after this? We won't need to take any more missions until the new year, so are you going to stay in our usual place or are you going to research more about Sound Levitation?" Michelle asked while looking outside the window.
Before Kai could answer, Tasha said, "I'll be staying in room 420. I don't know why, but I can concentrate better there."
"Isn't it usually the other way around?" Michelle couldn't help but comment. Usually, one wouldn't be able to concentrate properly when they were around many people, especially when those people were talking and disturbing their concentration.
