Lastation Technology Expo (ラステイシオヌテクノロジーエクスポ,Rasuteishion Tekuronojii Ekusupo?) more commonly known as the Tech Expo (テク エクスポ,Teku Ekusupo?) is a very important event inside the landmass of Lastation. Occurring every four years, it is the demonstration of various forms of invention based around a certain theme. This year's theme, as chosen by the Parliament, is Weaponry. Although it has been assumed that Avenir has played some part in this decision, and have known of it beforehand, considering that they had been preparing for this expo for three years, when the announcement of the type of invention was announced that year.
