1 ~ The Butterfly Effect

After destroying yet another city, Team Natsu faces the punishment of cleaning the guild's basement. Everything seems to go as planned, until the group activates a magical book that sends them back to the past. The four try their best to not interfere with their past selves, but a minor encounter changes everything. As they are sent back to the present, they feel relieved that nothing has changed. But, they found that they rejoiced too soon.
