2x4 - Mahoromatic

Mahoro receives word from Vesper headquarters that theres a dangerous item hidden under the school somewhere on the premises. Later reports confirm that it might be a bomb. So, Vesper has Mahoro go and find the item. The Caretakers organization gets word of this, and when the item is found, they try to take it. Meanwhile, the students believe its a magic love-granting item, so they too try to take it. However, it ends up being Shikijou-sensei's time capsule from her student days, and she was trying to find it before the construction workers did.
