Yes, pixiv is like the japanese deviantart. I spent hours looking through all the fanarts. Of course you need to try to input japanese characters in the search to get the best results. If someone feels like giving it a try, copy and paste these:
クロノ トリガ - Chrono Trigger
クロノ クロス - Chrono Cross
ラジカル ドリーマーズ - Radical Dreamers
I actually thought Vivid Soul was a personal gallery of someone, but I didn't actually look around the website, I went straight to the "クロノ"(chrono) section
Apparently the part of the website that is password protected is an adult section... um... interesting.
EDIT: Yes, is an adult section... and you don't need an account, you just need to read the instructions in japanese... eh, um....>_>Now. I feel like sharing some Radical Dreamers love today with you guys
