Yuudachi (a Touhou LW original) refers to a rain shower that falls on a summer afternoon. This is an apt temperament for Mike, a descendant of a legendary maneki-neko who beckoned a certain feudal lord into Goutoku Temple. Mike is endowed with Metal Phase, as she brings in fortune, and Star Essence, since inviting either money or customers would lead to the detriment of the other. The cold and silent Metal Phase resists Earth Phase, because earth bears metal, but it is weak to Fire Phase, because fire refines metal. The diverse and uncooperative Star Essence resists the cooperative and indecisive Moon Essence, but it is weak to the charming and arrogant Sun Essence.

Mike Goutokuji's ability as a maneki-neko. It is said that her ability to invite either money or customers and drive the other away is the imperfect form of a maneki-neko's ability. Attracting customers and increasing the average expenditure of each customer are essential concepts that form the basis of any business. The more customers you attract and the more they pay, the higher your profits. However, it is not easy in business to attract more customers and increase sales per customer simultaneously. It is not uncommon for one to go down when the other goes up. The former requires advertising expenses, and the latter involves research and development expenses. It would be unfortunate if the profits did not improve after paying these expenses, right? Maneki-neko are a magical sales promotion method that targets and invites customers who spend more money. It is also called targeted advertising. But Mike cannot do this. She takes it easy and repeats her usual fluctuating business methods. When many customers come, the amount spent by each customer decreases, and when she puts high-priced items on the shelves, few people will buy them. She may also have a sale once in a while. However, although the high volume of sales at low margins may look glamorous, the overall profits are markedly average. The maneki-neko at Goutoku Temple are all white cats that do not carry koban (oval gold coins). Mike seems to have had a difficult experience at Goutoku Temple because she was born a calico cat. However, Mike didn't let that get to her and learned the art of attracting customers on her own. She has now become a picture of the most commonly seen maneki-neko in Japan―a calico cat carrying a koban. There are theories that a maneki-neko's right hand attracts money and the left attracts customers, and it is also said that a maneki-neko who raises both hands brings bad luck. However, in Mike's case, the one she doesn't beckon is driven away, so perhaps she is self-taught in this area. It is generally said that maneki-neko originated from how cats were seen as lucky animals because they help exterminate rats that eat rice and silkworms. However, there is a different legend about the maneki-neko of Goutoku Temple. A cat is said to have beckoned a certain feudal lord to take shelter from the rain, which protected him from lightning strikes. Thanks to this founding maneki-neko, Goutoku Temple received a large donation and became the large and successful temple it is today. That maneki-neko was indeed a cat of good fortune that brought in luck.
