Heiter

Heiter (ハイター) was the alcohol-loving priest of the Hero Party. After the Hero Party was dissolved, he returned to the Holy City and eventually became a bishop. Heiter had very good health, which allowed him to live a very long life by human standards, even despite his passion for alcohol. In his last remaining years, he adopted the orphan Fern and raised her. When Frieren came to visit him twenty years after Himmel's death, he asked Frieren to adopt Fern and train her as her apprentice.

Personality
Heiter was an outwardly cheerful man who often diffused tense situations with his laughter and jokes about his inclination towards alcohol. He was easily moved to tears, both when things happened to the party or when he was hungover. However, inwardly Heiter was shown to be cynical about their odds of defeating the Demon King. As a child, this manifested in jealousy towards Himmel and he often outwardly expressed his doubts about being able to defeat monsters or eventually defeat the Demon King. However, he eventually decided that even if he could not believe in himself, he would believe in Himmel. As Himmel notes, from a young age, Heiter has always been very pious. Heiter was shown to be shrewd, as he was able to leverage Frieren's perception of time to trick her into staying and training Fern long enough for her to become a mage capable of traveling with Frieren.

Appearance
Heiter is a bespectacled Priest with short green hair that he keeps slicked back. A few pieces of hair frame his face.

Abilities

 * Mana detection: Heiter could accurately gauge the mana of other mages, estimating that Frieren had around a fifth of his mana when he first met her. Heiter was also able to detect that Frieren was restraining her mana, a feat that even a Sage of Destruction, Aura the Guillotine, was not able to accomplish. He would later use this knowledge of restraining mana when raising Fern to be a mage.
 * Immense mana: Heiter's mana pool was fairly large. He estimated that Frieren, who was restraining her mana, had around a fifth of his mana. Aura stated that Frieren's mana had not significantly changed from 80 years ago when she traveled with the Hero Party, but even this restrained mana was indicative of roughly 100 years of training. This means that Heiter, as a young adult, possessed around 500 years of training worth of mana.
 * Goddess's Magic: As a Priest, Heiter is capable of utilizing Goddess's magic from the scriptures.
 * Healing magic: Heiter is shown to be able to heal wounds using the scriptures.
 * Three Spears of the Goddess: Heiter learns this spell before he and Himmel set out on their journey. He is able to control the direction of each of the spears.
 * Spell that allows survival without nutriment and oxygen: A supportive spell that allows the one affected by the spell to not need food, water, or oxygen to survive. Heiter can maintain it for up to two months.
 * Spell to prevent trigger of mana detection: Stealth magic that makes those affected by the spell unable to be perceived by mana detection. It is cast in a circle around Heiter.

Trivia

 * Heiter in German means "cheerful."
 * Whenever Frieren called him a "Corrupt Priest," his usual response was to laugh.
