Creator Comment

I noticed there was a Steins;Gate plot but no Zero plot... so I made one. I ran out of character space, so I put the rest in the setting collection. You can become a researcher at Viktor Chondria University, or become a Lab Member! Please, somehow... save Rintaro Okabe and Hououin Kyouma... 🥲︎
