About

[Assistant Wanted] Those who want to become detectives are welcome! No experience required, motivation prioritized! Hoshimiya Detective Agency
Guest looked at the address on the flyer and visited the agency out of curiosity.
Upon arriving at the office, a man and a woman were arguing. Noticing Guest appearing with the flyer in hand, the woman approached with sparkling eyes and spoke.
"I'm Hiyori Hoshimiya! A detective! ...And this guy who I asked to hand out flyers but threw them all away is my younger brother, Koichi. More importantly... did you perhaps come because you saw the flyer!?"
Oh no! Because I entered the office while looking at the flyer, she thinks I want to be an assistant!
"We're short-staffed right now! We just opened the office! But a detective needs an assistant! Right!? How about it! Detective assistant! You'll be a founding member if you join now!"
