I appreciate your request, but I should note that this Japanese text appears to be a title or heading that references "Kobold Musou" (a specific work), discussion of its "failure to be published as a book," and related matters. However, the text as written is somewhat fragmented and unclear. Here's the most literal translation: "Regarding Kobold Musou's 'Failure to Be Published as a Book' and Related Matters" Or more naturally: "On Kobold Musou's 'Publishing Failure' and Related Topics" Note: Without additional context, some nuance may be lost, particularly with "彼是" (karekoze/are kore) which can mean "this and that" or "various matters."

It's just a story of failure in getting a book published due to lack of talent/ability.
