Tokimeki Memorial

In this episode, Riku Aoba has been placed in charge of his class' cultural festival project, a haunted house. But, building the house is a huge task, so he asks the science teacher for help. When the class sees the tent, however, they're surprised to see it has taken up a space as big as the school, and they don't have enough decorations for it. To make up for this, Riku asks the Goddess of the Furnace to summon real ghosts (Harmless, yet mischievous) for the tent. At the same time Sayuri notices Riku's new popularity and feels slightly jealous. (Source: Wikipedia)
