Why do servants in light novels sound so stiff?

The butler in a translated light novel talks like a man reading from a plaque. "Yes, my lady. As you wish, my lady. This humble servant will see to it." Readers ask whether Japanese servants really sound like that, and the answer is that they sound like something, and the something is keigo, which English has no way to be.

What keigo is

Keigo is the polite register of Japanese: a set of verb forms, prefixes and vocabulary that raises the person you're speaking to and lowers yourself. It has layers. There's the plain polite form everyone uses with strangers, and above it a formal system with separate words for what a superior does and what you do for them. A servant, a shop clerk, a junior officer and a student addressing a teacher all live in keigo for most of the day. It's grammar, not personality.

What it means in the source culture

Keigo in light novels is how a character shows their position without a word about it. The maid uses honorific forms toward her mistress and humble forms about herself, and a Japanese reader hears that as correct, the way English readers hear "please" as correct. There's nothing stiff or cold about it. The butler who speaks in full keigo is a professional doing his job well, and the warmth, if there is any, lives in what he says rather than in the forms he says it with.

The register also moves, and the moves are the drama. A knight who drops from keigo to plain speech with his lord has either been given permission or lost his temper. A maid who addresses her lady by name in a crisis, without the forms, has crossed a line the book has been drawing for a hundred chapters. And the reverse: a character who switches into keigo with a friend is putting distance between them on purpose, and the friend will feel it before the reader does.

How translators handle it

Most reach for a Victorian butler. "Very good, my lord." "If I may, my lady." "It shall be done." This is the closest thing English has to a professional service register, and it works well in a setting with dukes and manors. The cost is that it turns keigo into a class marker when in Japanese it's a situational one; a Japanese office worker uses the same forms with a client, and no English office worker sounds like a butler.

The second option is plain modern English with "sir" and "ma'am" and no contractions. It reads cleanly and disappears into the page. It also flattens: the difference between the plain polite form and the deep formal one is gone, so a maid speaking to a shopkeeper and the same maid speaking to the queen sound identical.

The third is the literal route: "this humble one," "the honorable young master," "I shall humbly receive." It preserves the machinery and produces English nobody has ever spoken. A little of it in a period fantasy can work as flavor. A whole book of it reads like a manual.

What we'd choose

Pick one English register per relationship and hold it. The butler gets his "my lord" and his uncontracted sentences, and he keeps them, so that when he says "you can't go out there" instead of "I must advise against it," the reader hears the forms fall away. We'd avoid the literal route except for one or two ceremonial lines, and we'd let the plain polite form be ordinary courteous English, saving the stiffness for the moments the original goes deep.

Suppose the young lady's maid says, in full keigo, that the carriage is ready whenever her mistress wishes. Two chapters later, with the house on fire, she says "run." The translation's job is to make the first line formal enough that the second line sounds like a different person, because in Japanese it does.

How to read it comfortably

Hear the stiffness as uniform rather than temperament. The servant isn't cold; he's on duty. Once you stop reading formality as distance, the affection underneath it becomes easy to spot, and the day the formality breaks becomes what it is in the original, a shock.

A translation that holds the register steady across a whole book is one where that break is audible; you can read it in Crossleaf.
