Internal Ranks are sort of a mini competition that decides based on attack combat and ignores Ranking, this is to more specify a person's combat class, so if they were graduated, they would be able sent out on mission more specific to their rank and combat for the fastest and well thought way, so if they were suppose to fight an enemey whom is Rank like 100 and they are Rank 90, combat class would be involved, or else they might die despite 10 Rank difference.
And here I'm Rank 150, killed a top 10 internal rank of the school. I opened the system menu, checked internal Rank, and there I was Internal Rank 10, Class 1-A Rank 450(School). Which surprises me as I didn't knew this year 150 Rank was so low._.
As I appeared in a boy's toilet cabin, and I wandered what should I do, and decided to walk to class and wait for my class instead of suddenly poof! So I as I opened the cabin, I saw a female undressing, which I immediately closed the door when she 'yelled pervert' I called back, why aren't you in a cabin than? And I felt some heat from behind the cabin door, and decided to use space power to poof! And go back to class.
While I appeared in class in my seat(I realised it was girl's toilet btw), I decided to self study, by that I mean learn every netbase attack/defend in the book. By studying I mean just flipping through pages(due to perfect memory) and just do categorize them based on use, (Yes in theory I can do this perfectly because I remember I categorize something and I remember what I categorized).
Now I'm perfectly good enough to defend on my own, but I can't memories any unusual powers since the school teaches such students separately with most other such students combine in another class at another time.
After a while, my classmates scroll into class, like real, its just students from Internal rank 100+ are here to challenge me, as they don't believe I got the rank for real, and I bribed the rank 10 guy. I sigh, as there was lots of battles, so I ran away with space powers again. And waited till Titles Training was over and poof back in class and this time my classmates saw it._.
After a huge sigh(the class is used to it), Miss Emily started teaching general stuff(Subjects base to keep our education).
