Comiket (Comic Market) is a biannual event happening in summer and winter every year for fans to get together to sell and buy fan-made material. Over three days, cosplayers, fans, and fan-artists gather in Tokyo Big Sight to celebrate their love for their respective fandom.
This year, I participated in the first two days of Comiket 84 as a cosplayer. Check out my Day 1 account here.
