Kenzo Tenma

I'm sorry, sir, have you seen this man from the photo?
He held out a photo of Johan.

Throughout the entirety of the series, his kindness is a prevailing characteristic that shines brightly. This is particularly noticeable when juxtaposed with Johan's unscrupulous and morally bankrupt nature. Our protagonist, on the other hand, frequently finds himself contemplating the moral implications of his actions, showcasing a deep sense of introspection. In moments of worry or concern, often in the company of Johan, he tends to neglect his own well-being to an extreme extent, pushing himself to the point of physical collapse due to lack of nourishment or sleep. Despite these occasional bouts of self-neglect, he manages to maintain an overall optimistic outlook on life, or at the very least strives to project this optimism to those around him. This is evident in his consistent efforts to offer words of encouragement and support to the individuals who cross his path.
When Lunge delves into Tenma's subconscious, he uncovers the unsettling truth that Tenma is an outsider in both Japanese and German society. Surprisingly, despite this lack of belonging, Tenma doesn't exhibit extreme social awkwardness. In fact, in various flashbacks, including those of Eva and Rudi, he is depicted as contentedly interacting with a group of people. However, when given the choice, Tenma tends to gravitate towards working independently rather than being part of a team.
Tenma firmly believes in the motto "All lives are equal," and this belief is deeply ingrained in his psyche. It goes beyond just his work ethic and influences his actions and decisions in significant ways. One instance where this belief is tested is when he disobeys Director Heinemann's orders to prioritize saving the person who arrived first, regardless of their social status. Tenma's decision to save someone based on their immediate need rather than their social standing reflects his unwavering commitment to the principle that all lives hold the same value.
