Armando is a war orphan that was taken in by a family of Tarutaru in Windurst when he was a child. His father was a Temple Knight that died in the Crystal War of 20 years ago. While his stepbrother, Lionx, was studying magic in the Aurastery's School of Magic, Armando was being taught how to fight by the Mithran women alongside his childhood friend, Suzanne. Now Armando is old enough to be an adventurer, and although he's learnt to fight with many weapons, he feels something's still missing. Holding on to memories of a man he barely knew, Armando sets out to find that piece of him that's missing, what it really means to be a knight.
