Cosplay Showcase

Cosplay Showcase

Show off your sewing, acting, and performance skills on our stage!

May 18th Update: Signups are now closed! Thank you to everyone who applied; staff will be in contact soon with more details.

For the past two years, we have been awestruck at all of the talented attendees who came to OffKai Expo in cosplay. This year, we are continuing to give them a place to shine on stage!

The Cosplay Showcase is an official event with hosts, a stage, and prizes. This event is not a contest! However, if we receive more sign-ups than we have time to showcase, we may prioritize VTuber-related cosplays, but please apply to show off whatever you like!

We are excited to feature the event on our Main Stage on Saturday, June 1 at 1:45PM to 3:00PM PDT, hosted by our guests, Annjelife and Domoarigathanks!

Each participant will receive a prize for being a part of the event. We’ll also raffle off some bigger prizes generously provided by some of our sponsors & partners (Sayu Sincro//Nisity, Studio Élan, and more!) among all participants at the end.


  • This is NOT a judged competition or masquerade! This is a walk-on showcase for cosplayers to display their work.
  • Participants will meet with members of staff around 30 minutes prior to the start of the event. Specific information will be provided closer to the event.
  • All participants will receive a participation prize for being part of the showcase.
  • In addition, we will raffle off prizes from some of our Partners & Sponsors (Sayu Sincro//Nisity, Studio Élan, and more!) among all participants at the end of the showcase!
  • Each participant or group of participants will be given time (90 seconds maximum) on stage. This time allotment is subject to change depending on the number of entries.
  • All cosplays and performances must adhere to Attendee Code of Conduct, especially the COSPLAY AND WEAPONS POLICIES.
  • Participants may provide music to OKE staff for playback during their performance.
