The character "ろ" is actually read as "ro;" the hiragana for "ra" is "ら." Similarly "は” is "ha," not "ho." Thus the author's name should be "Shihachiro."
... Fortunately this seems to be the only thing amiss in your work. Not bad.
@Darth It isn't, but I'm severely out of practice and to begin with had no experience to begin with. I've translated a handful of things before but never really with much skill. @aurumauriga Sorry, ended up doing some of it on low sleep so I misspelt his name in the tags, my bad. Thanks though!
Edit: @my little donger Fixed! Thank you for the heads up.
