Fairy Tail OVA 8 English Subbed Episode Title:Natsu vs. Mavis.Episode Description:Mavis joins the girls at Fairy Tail's bath house, unhappy that she cannot enjoy the qualities of a hot bath in her incorporeal form. Erza recruits Natsu to heat the bath water to extreme temperatures, successfully allowing Mavis to experience its warmth. Although Mavis is pleased with the bath, she appears to remain upset about something. Warrod visits the bath house with a job request to find a box Mavis buried under a tree 100 years ago. Natsu and his friends accept in the hope of cheering her up with the box's unknown contents. After uprooting every tree in Magnolia, the wizards find the box by digging up the underground tree Natsu's house is built around. Mavis appears and explains she is not upset about the box; rather, it is the hundred-year anniversary of her bidding farewell to her friend Zera. The wizards open the box to find a crude drawing of Mavis and the guild's founders, which is framed in Natsu's house, now perched atop the tall, unearthed tree.
