Apprenticeship alien of this story hero is goofy. He is so cute. His trainer is little strict. So the trainer's line of sight to watch him while flying is my favorite point. I think that it would puzzled as alien when there is so much control button of UFO. I understood feelings of alien why smile wryly when he miss press many times many times. And, until he guess right button, alien's purposes boy act violently in the room by the operation of the alien. This scene is laughed me. But, if I were this boy, I would woke up When he hit the body to the wall. So, I thought that he was pretty deep sleep. I think best nice point, it is expression of character in this story. It is strange that I can see little strict trainer's expression is pretty well at the end. I hope he grow up to be pilot full-fledged early.
