Mukashi Yuusha de Ima wa Hone

Alvis perished in a battle against the Demon King but awoke as a skeleton. After three years of rest and leisure, he sought out his old friend Izana by becoming an adventurer under the name Al the Skeleton. His skeletal form caused complications, yet he continued to take on various tasks such as guarding merchants and exploring dungeons. Using his sword, Al the Skeleton accepted new challenges to help others.
