Spireska

Spireska is a platonic ship between Eska Devereaux and Spiro.

Eska
When Eska first came to Castleton, Spiro was skeptic about her. However, Eska was still very friendly to him. After Eska tried to fight ghosts and messed up, Spiro cheered her up by advising her to fight ghosts her way.

When all the color was draining from the kingdom, Spiro blamed Eska, but immediately took back what she said. But, Eska still felt hurt and ran.

Spiro still cared for her by sacrificing himself to save her from Opex. When Eska did defeat Opex, she still felt upset when Spiro died in her arms. However, the magic from her wand brought him back to life, and the two became friends.

Disney Magical World: The Adventures of Eska Devereaux
In, The Ghostly Beginning, Eska chooses Spiro to be her sidekick, but it doesn't work out between the two, which causes them to argue. However, after finding out that the ghosts have a new boss, they reconcile and become not just fighting partners, but best friends.

Afterwards, the two have been on many adventures together when fighting ghosts or restoring color.
