View source for High School DxD: Names and Terminology Guidelines

This page is a list of unique/semi-unique terms and names for translators and editors to maintain consistency with. If anything significant needs to be done, such as any large additions, disputes to listed translations to a term or name, or formatting issues, please feel free to post them at the [http://www.baka-tsuki.org/forums/viewtopic.php?f=44&t=4904 High School DxD - Names and Terminology] discussion thread.

==Format Standard==

===Style of English===

All edited translations are to be in British English.

===Narrative Tenses===

Translators are allowed to use whichever tenses they need, so editors have to fix any errors for tenses when you find one. Narrative tense should be in past tense, although in some cases present tenses or future perfect tenses are preferred. Narrative does not mean the character dialogues.

===Stuttering===

If the word is a proper noun, proper adjective, or common nouns used as essential parts of proper nouns the stuttered words should be in capital letters. 

Example 1: “B-Bucho, what is it?”

If the stuttering occurs at the beginning of the sentence and it is not a proper noun, proper adjective, or a common nouns used as essential parts of proper nouns, then the first stuttered letter should only be capitalised while all the other succeeding letters should be in lower case. If the stuttering occurs in the middle of the sentence, then everything should be in lower case letters. 

Example 2: “Eh? B-but, don’t you have to get yourself a husband?”

Example 3: “I've g-got to p-pick up a new b-book on vampires, m-myself.”

===Japanese Honorifics===

Since there are no equivalents to Japanese honorifics in the English language, Japanese honorifics will be kept.  

===Japanese Loanwords===

There are some words in the Japanese language that do not translate into the English language, for such instances it is recommended to keep the Japanese loanword. For example, Torii.

===Translation Notes===

Akuma means both devil and demon, the Japanese do not differentiate between the two. Similar to how nezumi means both rat/mouse. In lieu of the context in High School DxD which involves a war between Angels vs Fallen Angels vs Devils. We will be using Devil as the official english translation of Akuma. Youkai will substitute for demons like nekomata and etc.

Maken means magic sword, but we're translating it as demon-sword in lieu of the setting of this series.

The Japanese naming standard has the family name followed by first name. For example, Hyoudou Issei. Hyoudou is the family name, while Issei is the first name.
