There is a large sacred tree in Alicia Forest near the village of Nemi. Once every year it’ll glow and if a couple vows to love each other under its glow, they will live happily ever after. Elmo is preparing for the the annual Easter of Sant’Ariccia festival. His adoptive father disappeared 3 months ago and he had to take over the graveyard duties. Every Tuesday midnight, he has to participate in the battle of ‘Eremita’. If he loses, Tuesday will be stolen from this world.
