If you believe in astrology, or you're just curious about it. Here's current (so no graduated) girls in Nogizaka by sorted their zodiac signs. Do you think your oshi fits her sign? The signs with most members are: Leo, Aquarius and Libra. Aries Taurus Gemini Cancer Leo Virgo Libra Scorpio Sagittarius Capricorn Aquarius Pisces
Chima is an aquarius, which definitely fits her. Idealistic, overthinking, clever, artistic, individualistic, independent, to name a few traits often associated with this sign. I'm an aquarius myself, maybe it's part of why I'm drawn to her.
In retrospect it should've been obvious, but I just realized Manatsu is named Manatsu because she was born in summer. “Manatsu” is usually translated “midsummer,” but it’s more like the "height of summer” or “hottest part of summer.” Although her birthday Aug. 20 seems pretty late for manatsu... So yes, whenever they mention Nogi’s Summer Tour, they are actually saying Manatsu no Zenkoku Tsuaa, “Manatsu’s National Tour.” Also, Hazuki (8/23) was probably named after the traditional Japanese calendar’s name for August, 葉月 Hazuki the month of leaves, referring to when the leaves start to fall.
