ข้อมูลอนิเมะFairy Tail OVA (2016)

Returning to Magnolia Town and recovering their Guild's building, Team Fairy Tail A and B bicker over which team will have the privilege to make the other team do whatever they desire for an entire day, as per the bet they made on the first day of the Grand Magic Games.

Some of the Fairy Tail members visit the hot springs for relaxation. Mavis joins the girls in their bath but reveals that she can only enjoy the atmosphere, not the qualities of the water. Erza calls over Natsu from the men's bath, causing the other girls to exit the bath in embarrassment, and tells him their problem. The Dragon Slayer immediately uses his Magic to drastically raise the temperature of the water, so much so that Mavis is finally able to experience the warmth to her great joy and excitement.
