Dayōn

**Dayōn (ダヨーン)**, originally **Da Yon** or **Dayōn no ojisan** early on, created by Fujio Akatsuka and Kenichiro Takai, is a supporting cast member of Osomatsu-kun and a part of Akatsuka's Star System.

## Overview

Before Dayōn's official debut in the -kun series in late 1965, men with similar wide mouths had appeared sporadically in the title but had lacked the verbal tics or other recognizable features.

Dayōn's role is often changing, with him usually serving as a minor character in a story no matter what his job position may be. However, there may be a rare occasion where he could be considered a protagonist or the ultimate hero.

## Physical Appearance

Dayōn is a middle-aged man of average height, with a slender body but a head with an abnormally wide mouth and cheeks. He is often unshaven, and dresses in business suits with geta sandals or simple shoes.

## Personality

He is a strange but often easy-going man who is versatile in what kind of jobs he has, easily fitting the role of a friend or enemy. His wide mouth makes him quite useful as well, as he can make snowmen by packing snow into his mouth and spitting it out as balls. Dayōn can also use this mouth to his personal advantage in eating as much food as he likes; he can stuff at least 50 apples in at once. Most disconcertingly, this mouth can also be used to attempt to devour people as well.

He enjoys haiku, as well as radishes. The official profiles ultimately describe him as an "unclear man who cannot be easily understood".

### Speech

He often ends his sentences with "da yon" or simply "yon".

## Relationships with Other Characters

### Iyami

Dayōn may have a neutral, friendly, or antagonistic relationship with Iyami depending on the story's needs.

### Brothers

In the setting of "The Sextuplets vs. The Great Gang of Japan", he is only one of three brothers that were separated during WWII and have only recently reunited through the story's plot. Each of the Dayōn have a different profession; one is a pilot, one a ship captain, and the other a truck driver.

### Wife

Dayōn can at times be seen to be married to a woman with a face identical to his own, minus the mustache.
