Yuusha Ikkou no Senzokui

Danger is always a part of the adventure. Fighting demons, injuries, harmful insects, and unknown diseases called curses. In a different world with no proper medicine, it is impossible to cope with them! A doctor who wanders into this world makes medicines, treats them, and supports and guides the new young heroes! A fantasy of healing and salvation that begins in a world where medicine is underdeveloped!
