Sweet Rein

Facing the prospect of spending the Christmas holiday entirely by herself, Kurumi Sagara decides to step out for a solitary evening walk to clear her mind. However, her quiet outing takes an unexpected turn while she is crossing the street, colliding abruptly with a mysterious young boy. Upon impact, a magical rein instantly materializes, binding the two of them together in an inexplicable connection. The overjoyed boy immediately addresses Kurumi as his master, declaring that she is destined to be his Santa Claus. Naturally, Kurumi dismisses his claims, writing him off as a lunatic with an overactive imagination. Yet, her disbelief shatters completely when the peculiar boy undergoes a sudden and astonishing transformation right before her eyes, shifting shape into a literal reindeer.
