Hi! I am Eriza! <3
I do cosplay and enjoy making costumes!

My cosplay journey started in 2010. At that time and for several months I had a sickness called “mycoplasma pneumoniae”, which kept me at home without any possibility of going out with friends.
When I started to recover, I had the chance to go to a convention where I saw some people doing cosplay. I wanted to give it a try too and with some friends we planned to attend to a convention with VOCALOID cosplays. I was KAITO, with a costume made by a seamstress and with details attached by hand by me.
Sadly, nobody else on the team finished their costumes on time 🙁 BUT! We enjoyed the event anyways, and I feel that this experience helped me a lot in my recovery process and was a great way to share with friends again!
This project inspired me to try to make my own costumes! My grandma gave me her sewing machine and I started to learn how to use it to make more projects during the following years. I also started to learn more skills, such as prop making, makeup, wig styilling, electronics, and many others. I am happy to learn new skills even until today!


More than a decade after my first costume, in 2021 I and my friend Daiki participated in the World Cosplay Summit Video Division. I cosplayed as Hatsune Miku V2 and my friend cosplayed as KAITO. (so nostalgic!)
To make these costumes, I applied many reflective effects and electronics and I learned a lot during the process! We did a cover music video of “MELT” by Ryo for the competition. With this project we won the Sound Directing award! Yay!


In 2022, I participated in the World Cosplay Summit Exhibition Event as Miu Iruma along my partner Javier as Kokichi Oma, from Danganronpa V3.
We put a lot of effort on Miu’s wig and the backpack, which includes a touchscreen, functional buttons, USB charger, servo controlled robotic hands and even a hand sanitizer that reacts to proximity! We won two awards with this project!

In 2023, I participated in Polymanga Global Easter Cosplay with my Hatsune Miku Celebration costume, where I won 2 awards!
I applied several dyeing techniques in plastics to get the colors that I needed. What makes this costume so difficult is that it has a lot of transparencies, which means that if you make a mistake in the boots or in the sleeves, you have to make that part again from zero!
Also, the whole costume has 8 LED circuits: 2 circuits in the giant bow on the back that connect more that 1000 LEDs that react to the sound, 2 circuits for the animated rainbows in the headphones, 1 circuit that connects the neon LED necktie, 1 circuit for the animated lights in the skirt and 2 circuits for the animated lights in the LED panels of the sleeves.
I am grateful that cosplay has helped me to recover from the darkest times of my life. It has given me the opportunity to meet the best friends I could wish and to inspire me to improve everyday with a smile.
I am excited about which other “cosplay adventures” will happen in the future!
Thank you for reading <3
