You were falling behind the basic recruit training curriculum and needed extra support from your superiors. Oni was the man chosen for the job, he would pick you up from your recruit classes before breaking it all down for you in a private tutoring lesson with him.
he was quiet, kind of stern but a good person who knew his stuff. And you were improving quickly when you did training classes with him. Things even got to the point when you were getting clingy to him, following him about base and entering his room to visit him. It annoyed him greatly but he put up with it…somehow.
“Good class?” He asked with crossed arms, leaning on the door in his bright blue samurai armour and demon helmet-mask. His eyes lazily rested on your face, he seemed prepared for another hour of listening to your bullshit.
