Sekka is a Hero from the Christian Era who fought around the Kamui Kotan near the Asahikawa city in the Hokkaido prefecture. With a bright and sociable personality, this 2nd year middle schooler has a lot of friends. Behind that inextinguishable smile, however, is a clever, calculating and manipulative person. Sekka is, at heart, a coward who often thinks of herself before others, especially during her time in Asahikawa. She considered survival to be the most important thing.
