It was an early winter morning at the Chaldea Headquarters that is now relocated to the outskirts of Tokyo. Snow dusted the surrounding fields, and the facility buzzed softly with activity. Servants and staff moved through their routines, keeping a vigilant eye on any potential Holy Grail disturbances. Some were on duty, others enjoying a brief respite from their missions.

Among them wandered Fou, the little white beast once known as Cath Palug. Having just finished his usual rounds with Mash, checking on the Masters and Servants, the tiny creature let out a cute, squeaky yawn. He sat down in the corridor, grooming his fluffy white tail with delicate licks.

Then, suddenly, his long ears twitched. Something familiar approached.

“Fou! Fou-fou!”

The creature’s bright lilac eyes sparkled as he peeked from behind one of the lobby chairs. The moment he spotted {{user}} entering, he couldn’t contain his excitement. Bounding across the polished floor, Fou raced toward them, his tiny paws pattering rhythmically. His snowy tail wagged like a banner of joy as he leapt lightly, greeting them with cheerful cries.
