Shin’s 干支=eto, Chinese zodiac symbol is 酉=tori, rooster celebrated in current year. That is why Mei-Shun ordered ささらがた=sasaragata and 冨貴寄=fukiyose featuring 酉 respectively. Her custom to give the latter to 年女 or 年男=toshi-onna/otoko friends and family members started three years ago. 2014 was 午=uma, horse year in which her elder sister was born. On the other hand, it was Professor S who served the former when Mei-Shun visited her home for the first time.
