Sharp-Tongued

Calm and Unbothered

No matter what happens, Kageyama stays calm and keeps his cool.

Not much is known about Kageyama’s history.

He keeps his past and why he works as a butler a secret.

He once mentioned that he wanted to become a professional baseball player or a detective.

He takes pride in his skills in both baseball and solving mysteries.

With Reiko Houshou

Kageyama is Reiko’s butler and chauffeur.

He serves Reiko every day, making sure everything is in order.

He often corrects Reiko when she makes mistakes—but does so in a rather rude way.

Reiko does not trust him very much as a butler, calling him "sketchy" or "suspicious."

With Reiko’s Father (Kiyotaro)

Kageyama sometimes makes subtle jokes about Reiko’s father, not always showing him great respect.

When Reiko is not home, Kageyama enjoys watching talk shows.

Sometimes, he learns about Reiko’s cases from the TV before she tells him.

“Are your eyes just for decoration, Miss?” (A sarcastic comment he uses when Reiko misses an important clue.)

The Unnamed Butler

Kageyama's real name is not known.

He is always addressed as “butler” or "chauffeur" by the Houshou family.

Solving Reiko’s Cases

Whenever Reiko faces a difficult case, she always tells Kageyama about it.

Even if she believes she has found the answer, Kageyama often points out what she has missed, always in a polite but biting way.

He then cracks the mystery brilliantly, leaving Reiko both amazed and annoyed.

At the Crime Scene

While Kageyama prefers to solve cases from the comfort of his own home, he sometimes visits crime scenes with Reiko.

He will only do so if it is necessary, such as stopping a possible second crime.

Rules and Methods

Kageyama believes gathering material evidence is the police’s job, not his.

He focuses on deduction and logical reasoning instead.

Hidden Past

Kageyama never shares much about where he came from or why he became a butler.

He jokes that he would have liked to be a baseball player or a detective.

Kageyama often seems amused by Reiko’s lack of detective skills.

Still, he assists her in every case and always makes sure she stays safe.

Despite his cold words, it is clear he supports Reiko in his own unique way.
