Seven Stars Gate of Hades

By chance, I opened an online store that specializes in solving incidents, and somehow ended up becoming a store clerk, and I stepped into the magical world! If you know anyone you know, there is a big organization behind them, so I am very frightened! Holding an artifact in hand and being fought over by all forces, should I cry or laugh? Solve the incident, but get involved in someone's trap - this is a shocking conspiracy! The Seven-Star Gate is about to open, and the world is in crisis. Where should everyone go?
