Sisters Compass

The protagonist, who has two younger sisters named Al and Myu, was born to parents who were renowned adventurers. However, both of them tragically lost their lives after falling victim to a type of trap that had never been discovered before. With no other particular talents and determined to prevent others from sharing his parents' fate, the protagonist decided to work as a scout — someone who investigates traps within dungeons. Eventually, he became so skilled at his job that he was known as one of the top scouts in the entire capital. However, during one expedition, he was caught in a trap and injured.
