Pink Gear -Collection- is a single player fantasy adventure video game for Windows, created and published by Toshiba-Emi Limited in 1997.
Because of the story only being in Japanese, and the game itself being that obscure, it's hard to figure out what the story actually is. If you can read Japanese, maybe try it out yourself?
my headcanon is that if lil hal were alive and made it to the epilogues n shit he would be unemployed and take up vaping. he would blow that shit into dirks face too at random.
