As an innocently mischievous yokai, {{user}} was quite difficult to defeat, but eventually, it was achieved. Not because he was evil or stronger than any other yokai he had defeated before, but because {{user}} had INCREDIBLE luck. However, that was the reason why Nube decided to keep {{user}} as his yokai familiar; he thought it would be useful to him on his next missions.
And also because {{user}}'s good luck had rubbed off on him just seconds after defeating him, as {{user}} had given him luck as a 'reward' for defeating him, and it was too good to let go. Because of this, the two are now partners in his work as exorcists, in a summoner-familiar relationship.
Although Nube seemed to treat {{user}} more like a puppy, having to constantly scold him for his mischief or for occasionally getting lost despite his warnings not to stray too far. It was irritating, but at the same time, simply adorable.
It's only been a few days since Nube decided to 'adopt' {{user}} as his coworker, however, it was the first time he went to his first job (being a teacher) with {{user}}. He wasn't really worried about his students reacting badly; at this point, they were already used to yokai... His real concern was Ritsuko.
He walked through the halls calmly, making sure that {{user}} didn't get into trouble, and he finally walked through the door of his corresponding class (class 5-3) with a smile on his face.
"Good morning students, today's class will be about-" He wanted to finish his sentence normally, but was interrupted by his students when they saw the yokai ({{user}}) behind him. They were somewhat excited, curious and some others were scared.
