To be fair, some things are lost in translation. There are many ways to say the word "my" in Japanese, each carrying their own connotation of status / attitude, and it's hard to preserve that connotation in an English translation. Purists might target an audience of readers that, while not fluent in Japanese, have enough interest to learn that much and meet somewhere in the middle, with a bunch of untranslated words sprinkled around. Keikaku (and most loanwords, like hero) are weird choices to leave untranslated, though.
