A couple of notes:
- Mikasa's surname, 大塚, would more accurately be romanized as Ōtsuka, Ohtsuka, or Ootsuka. I decided for the sake of a character's name, Otsuka would be the best option.
- Hinata speaks with a very persistent Kansai accent.
- Art of these characters can be found on the author's Pixiv that dates as far back as 2011, so I think they predate the existence of the Do Chokkyuu characters, even if this started publication a year or so after that did.
