Fairy Tail Season 9 Episode 30

Gray and Juvia

As Gray and Juvia battle each other against their wills, Juvia resists Invel's control enough to stab herself with a blade of water, only for Gray to impale himself with an ice sword simultaneously. However, Juvia uses her water magic to transfuse her blood into Gray, saving his life as a result. A grief-stricken Gray defeats Invel, unaware as Wendy and Carla heal Juvia. When Gray retains his judgment and refuses Invel's request to kill Natsu, Invel reveals Natsu's identity as E.N.D. to him in another attempt to trigger Gray's corruption. Meanwhile, Brandish tries imploring Natsu, Lucy, and Happy to abandon the battle to save them from the rest of Alvarez's forces, but is shocked when Natsu easily defeats a magically enhanced Neinhart.
