Reborn as an Aristocrat, Yet, Why Are My Sisters Bro-cons?

A guy finds himself in an absolutely new world. He knows nothing about himself, but he doesn't care. Despite the fact that he tries not to mess with the nobles, Astro himself becomes a noble ~~~~~~~~~~~~~~~~~~~~~~~~~~ The world with the system. But I don't like it at all, so I'll use system only to show stats of mc. Just to point it AGAIN - there is system in this world, but i HATE systems with passion. I'm not gonna make my MC useless piece of garbage who depends on it. So, if you're looking for System FF, it's not your cup of tea, for sure World travel later.
