I am trying to identify an anime I watched on TV in Europe during the summer or Christmas holidays of the 2010s while traveling through many different countries. I remember it aired on a channel that also showed Naruto and Bleach around 8:00 PM or 10:00 PM, likely as part of a specific programming block. I might be mixing 2-3 shows, but the ending is very specific.

The Ending (Most Vivid):

• Transformation: A male character turns into a light blue, 6-legged fox/beast (size of a fox) with dark tiger stripes.
• Action: A heroine in long clothes kisses the beast on the forehead.
• Vanishing: He runs up a small hill/rock, looks back at the party, and disappears.

Other Scenes (Might be from a different show on the same channel):

• A huge beast attacks a castle.
• Men in armor on horses attacked by tree tentacles and flying demons (bloody action).
• A transition from jungle to a desert with a huge black tower (LOTR style).
• Curse possibly from a "Demon King."

Style: Hand-drawn, medieval fantasy.

Does anyone recognize the 6-legged blue fox or the vanishing ending?
