Hakuouki is one my fav.

For Adobe, right? Adobe is really RAM eater.
You have to buy a laptop with upgradeable RAM slot at least 16 GB. Go for Intel because it's faster than AMD. For the processor, don't buy something ended with U, because it's slow and more into saving battery. Go at least for M processor. Buy those with good graphic card, Nvidia usually more compatible with software, grab the GTX. For te HDD, buy at least blue one for WDC or Seagate. 500 GB minimal. Or you can just buy an external HDD or SSD (if you want faster performance). Small monitor is not a problem, you can always connect it to external monitor because most of laptop monitors don't have good color except for Apple's product but Apple is way too expensive.
