Oi~ssu! I'm Yuu,


Developer? Designer? Something along the lines. I like Isara Mao and Kamishiro Rui a normal amount.

Oi~ssu! I'm Yuu, a designer/developer from Thailand. As a student, I did a lot of graphic design work, so I thought a dabble at frontend dev would be fun—and here I am!

When Ensemble Stars!! caught my eye back in May 2020, I immediately played and loved it. I started helping out the game's wiki for fun, and not long after I created Oi~ssu♪, a script for formatting the game's translations with over 20k current monthly users!

In my free time, I'm either coding, playing Enstars or Project SEKAI, or retweeting all the Mao / Rui fanart I find on Twitter. If you ever see me on your feed, feel free to drop by and say hi!
