[Comprehensive + Arknights] Diary of Master's and Phd Studies

In the COC division of the holographic game "BOX", I was invincible in many battles, and the system (KP) tore off not one thousand but eight hundred cards. ... Until I traveled through time with my last weak, pitiful and helpless doctor card. Yes, just wear it. Even if I get to Chaldea and save the world with a group of heroic spirits, it doesn't matter. …To this day, I don't know whether I was dreaming or wearing it again. In front of me, a beautiful girl of unknown orc race was holding my hand and calling me "doctor" affectionately. This girl, how do you know that I am a doctor with your sharp eyes? !
