This letter was written by Masuyo Toby to Konata Izumi, claiming that she had violated the Decree for Underage Gambling Act of 1995, after a muggle, being Yui Narumi, had caught Konata gambling on her computer.
Dear Ms. Konata Izumi,
We have gotten reports that a muggle had sought you gambling outside the Lucky Star Kingdom. As you know, drillers under the age of 17 are not permitted to gamble outside the kingdom under the Decree for Underage Gambling Act of 1995. Any future offenses may result in expulsion from the kingdom, and we also recommend that do this in simulation and not with a real currency.
Hoping you are well,
