... Well, putting aside the weird issue of using a decimal point as a comma (given they mean completely different things in terms of numbers)... this is a bit of a weak start. Kinda nonsensical without really being funny. I hope it gets better.
Like... why does she want to go to school?
Why does she want only high-quality products to the point of threatening physical violence if she doesn't get them, but can't even distinguish between high-quality and low?
If she is having fun, why does she keep making trouble and being a spoilt brat?
And for that matter, if all she lived for before were her missions, how is NOT doing any supposed to be more fun?
How did she know what to do with that other yakuza gang, let alone who the boss was?
Why does she threaten to leave when said before that she had nowhere to go?
... It just seems to be a complete mess of inconsistency at this point.
