Hiroyuki

Hiroyuki (ヒロユキ) is one of the major characters in the Ninku series being Fuusuke's pet penguin and one of his 4 main travel partners.

In the anime, he is commonly referred to by Fuusuke as the strongest penguin in the world honing to his immense strength and powerful farts.

Appearance
Hiroyuki is a small African (Magellanic in the manga) Penguin with large round eyes and an orange beak. In the manga, Hiroyuki is often expressing one emotion whilst doing something typically comedic like playing bingo or playing tag with Fuusuke in the Woods.

He speaks in a custom animal speech that is differentiated in the media ("Puri Puri" in the manga and "Debi Debi" in the anime).

Personality
Hiroyuki's personality varies depending on his appearance in Ninku.

In the First Stage of the manga, he is labeled as a stupid penguin that wanders around aimlessly and poops everywhere, and is considered to be a foil to Rihoko's seriousness after she is introduced. Some examples include him casually walking into the middle of Fuusuke and Kousho's battle or playing bingo when Rihoko is panicked about Fuusuke, Aichou and Touji's whereabouts. However in Second Stage, Hiroyuki's personality became more akin to his anime counterpart, being more expressive and aware of his surroundings.

In the anime, Hiroyuki is more competent and spontaneous. He takes on an array of emotions depending on the situation at hand and is very loyal to Fuusuke even after Fuusuke considered to leave him for his own saftey.

Powers and Abilities
In the manga, Hiroyuki is unlike any ordinary penguin. He has been shown to run as fast as Fuusuke and tag him in a game of tag. Also despite being called stupid, Hiroyuki has preform actions that humans can such as playing bingo being a more known example.
