Himmel

Himmel was the Hero of the Hero Party. With the help of Priest Heiter, Mage Frieren, and Warrior Eisen, he defeated the Demon King, creating an era of peace. After his death from old age, Frieren resolves to get to know Humans better, making him the catalyst for the main storyline of Sousou no Frieren.

Personality
Himmel was a laid-back and friendly man who appeared to get along with others easily. Even in times of strife, he was extremely devoted towards protecting the people, and went out of his way to assist others. This devotion inspired his companions to be kind as well in order to carry on his legacy--notably, when Heiter saved Fern from suicide and raised her as his own with the reason that it was what Himmel would have done.

Contrary to his otherwise-heroic persona, he was slightly narcissistic at times, declaring himself to be handsome and taking great care of his appearance even as an old man.

It is heavily implied multiple times throughout his adventures with Frieren that he held romantic feelings for her, though she did not notice these feelings.

Appearance
Himmel was a male Human with blue hair. He was self-declared to be handsome, and took great care of his appearance, even in old age.

History
After defeating the Demon King, Frieren left the group to pursue her studies, unaware of the different sensations of time experienced by her non-elf comrades. When she finally returns, Himmel, now an old man, greets her. They reunite their group for one last adventure, before Himmel passes shortly afterwards.
