A hairstyle in which some locks of hair are tied up on both sides of the head while the rest of the person's hair hangs normally. Neither length or volume of the tied up hair nor that of the other free-flowing hair matters for tagging purposes, only that the remaining hair falls down loosely.
Not to be confused with twintails, where all of one's hair is tied up into two ponytails and nothing is left to fall freely.
Examples include Tohsaka Rin, Ultimate Madoka, Onozuka Komachi, most depictions of Kawashiro Nitori, Nena Trinity, and Souryuu Asuka Langley.
Two side up requires the back of the hair to hang freely.
These posts are twintails, not two side up. The back of the hair does not hang freely outside of the twintails.
