She grew up without a mother and sees her entire village as her family. Her master, Morissimo, is over 60 years old while the village chief San is even older. Although Martina's lifespan is longer than a normal human, she refuses to discuss her age. The Fire Tribe seemingly has a few secrets, and those will be uncovered throughout this story.

After finding what looks like a bike helmet with a symbol in an ancient ruin, she has spent every day attaching armor to it and enhancing it in the smith. Her muscles and stamina make her as powerful an attacker as Donelia and a reliable ally in battle.

This rumor started spreading after she got into a fight with a mercenary and won one day. She was discovered by King Morgaia and joined the Royal Knights, but she has since left them and now spends her days as a dungeon-crawling adventurer.

She has a twin sister. While traveling in search of information about their birth and why they were orphaned, they passed through the Magical Kingdom of Tychlluina where her sister became one of the Royal Mages.

During that time, she gained a certain degree of cultural knowledge as well as an improved salary, but the darkness in her heart remained. One day, Mercenary King Morgaia sent two powerful but inexperienced Royal Knights to fight Donelia, but she defeated them. That's how the Mercenary King came to ask Donelia to join the knights.
