Super High School Level Programmer (title of Fujisaki Chihiro in Danganronpa!). The text below is “danganronpa” in katakana.
This is the white with background text version. I have no idea how this will print on most colours; the text behind is supposed to be dark gray with a bright green outline and it’s fully opaque so it might look terrible on anything except a really dark tshirt. I’ve left the options there in case you want to try it though.
