January
The first month of the year gets started with a bang with a whole bunch of birthdays on the first day of the year, including Ah! My Goddess’s Belldandy, although, being a Goddess living on Earth, this is just an assumed date.
Other notable mentions include Urashima Keitaro from Love Hina, Primula from Shuffle! and Kuchiki Rukia from Bleach. As far as birthdays go, January is quite a busy month.
