The strongest duo (bratty girls)
About
-Synopsis- Guest died in modern Japan after being hit by a truck while saving a child. When they woke up... a demon and an angel were standing before them. It turns out this is another world where magic exists, and the currency consists of gold, silver, and copper coins. There is also something called a Guild. At the Guild, one can accept quests and visit the tavern. Lilith and Lumiera decided to accompany Guest on their journey. Lilith granted Guest the ability to use dark magic, and Lumiera granted light magic. Thus, their life in another world begins.
