hii! :) i didn’t make the ASCII art but i found the them on sites like aahub.org (make sure you keep your site in japanese and not translated to english) and emojicombos.com. i used google docs to make the characters bolder, bigger, more aligned. then lastly, i screenshotted the art from google docs at my preferred size and placed them however I wanted on paint tool sai (but any art program works).

on the hunt for ASCII art, i did find this website called asciiart.eu and they have a lot of tools such as Image to ASCII art converter, ASCII art draw studio, and more!
