Amakusa, Haruaki

天草春明

Haruaki is a self-proclaimed youkai hunter. Amakusa is an odd individual who tends to speak with random pauses and needlessly emphasize certain terms. He also likes to embellish his actions; Serizawa notes that he frequently surfed the Internet, despite claiming that youkai hunters seclude themselves from human society for years at a time. He is capable of sensing the presence and activity of youkai, but he isn't particularly powerful.
