I AM DESPERATE, HELP ME PLEASE

What's up guys? So I've going through dozens of pages after this one manga... BUT I CANT FIND IT! The worse part is that I remember too little about it, here it goes...

I am not sure but I believe it fits into de reincarnation tag, I remember specific events like he has these powers (not sure if it's here the reincarnation tag enters like he retrieved old memories of who he was and that he was super strong or something), his sister is training to be a idol I even remember he once took her forcefully in the middle of a concert and there's also the part I remember the most was that when he decides to do his military service and nobody really liked him since he was awesome at everything furthermore his expression didn't really chance lol he was most of the time expressionless. I also thinks there were two organizations that hide themselves from the world but they also make use of the same kind of power the MC has and he refuses to be part of any of them because y'know he was strong enough by himself. HELP!
