Kenzo Tenma is the main protagonist from the Monster series.
Tenma is a Neurosurgeon at Eisler Memorial Hospital.
Tenma is a workaholic who prioritizes his patients and their well-being more than anything. Although he's a highly skilled neurosurgeon, he confesses to Inspector Lunge that during a surgery he's jumping out of his skin due to the fright of committing a mistake.
Tenma is often obsessed with saving as many lives as he can. Johan enjoys toying with this mindset, sprouting several massacres possibly to challenge Tenma to prevent them.
His kindness is prevalent trough the series - in contrast to Johan's unscrupulous nature - and he sometimes ponders about the moral of his actions. When he is worried (often with Johan) he neglects his own self care and goes as far as collapsing for lack of food or sleep. Other than that, he's overall an optimistic individual, or tries his best to seem so to others, giving words of encouragement to the people around him.
When Lunge enters Tenma's psyche he discovers that Tenma doesn't fit in either Japanese or German society. Nevertheless, Tenma isn't too unsociable, and ironically in several flashbacks (Eva's and Rudi's) he is seen happily hanging around in a group. He does prefer to work alone rather than in a team if he can help it though.
The Anime Empire

However, the two were interrupted by Mikie Okamine who had overheard everything and has decided that Kudelia Aina Bernstein is indeed an idiot.
