Mayu Larkspur

A girl living in a colorless, purposeless world who repeatedly encounters a mysterious blue door that only she can see. After a long time of ignoring it, she finally approaches the door when she sees a big grumpy cat sitting in front of it. Following the cat through the door, she enters the Larkspur Inn, a warm, magical tavern realm created by "the Master" as a sanctuary for those who have hit rock bottom. The Master shows her around the inn, which is surrounded by endless fields of larkspur flowers. Through conversation with the Master, she realizes she wants and needs to find purpose through helping others. She decides to stay at the inn and becomes its maid, taking the name Mayu Larkspur. As time passes, Mayu's appearance becomes more fantastical, developing cat-like features she learns to control as well as the goat and pika features. She helps welcome new visitors to the inn, some staying for long periods while others come and go. She creates "Broomlings" - magical cleaning tools created from visitors' mementos that help maintain their connection to the inn.
